Cybersecurity & GenAI: How to Secure Your Systems Against the New Risks of Generative AI

Cybersecurity & GenAI: How to Secure Your Systems Against the New Risks of Generative AI

Auteur n°3 – Benjamin

Content:

The rapid adoption of generative AI is transforming Swiss companies’ internal processes, boosting team efficiency and deliverable quality. However, this innovation does not intrinsically guarantee security: integrating language models into your development pipelines or business tools can open exploitable gaps for sophisticated attackers. Faced with threats such as malicious prompt injection, deepfake creation, or hijacking of autonomous agents, a proactive cybersecurity strategy has become indispensable. IT leadership must now embed rigorous controls from the design phase through the deployment of GenAI solutions to protect critical data and infrastructure.

Assessing the Risks of Generative Artificial Intelligence Before Integration

Open-source and proprietary language models can contain exploitable vulnerabilities as soon as they go into production without proper testing. Without in-depth evaluation, malicious prompt injection or authentication bypass mechanisms become entry points for attackers.

Code Injection Risks

LLMs expose a new attack surface: code injection. By carefully crafting prompts or exploiting flaws in API wrappers, an attacker can trigger unauthorized command execution or abuse system processes. Continuous Integration (CI) and Continuous Deployment (CD) environments become vulnerable if prompts are not validated or filtered before execution.

In certain configurations, malicious scripts injected via a model can automatically propagate to various test or production environments. This stealthy spread compromises the entire chain and can lead to sensitive data exfiltration or privilege escalation. Such scenarios demonstrate that GenAI offers no native security.

To mitigate these risks, organizations should implement prompt-filtering and validation gateways. Sandboxing mechanisms for training and runtime environments are also essential to isolate and control interactions between generative AI and the information system.

Deepfakes and Identity Theft

Deepfakes generated by AI services can damage reputation and trust. In minutes, a falsified document, voice message, or image with alarming realism can be produced. For a company, this means a high risk of internal or external fraud, blackmail, or disinformation campaigns targeting executives.

Authentication processes based solely on visual or voice recognition without cross-verification become obsolete. For example, an attacker can create a voice clone of a senior executive to authorize a financial transaction or amend a contract. Although deepfake detection systems have made progress, they require constant enrichment of reference datasets to remain effective.

It is crucial to strengthen controls with multimodal biometrics, combine behavioral analysis of users, and maintain a reliable chain of traceability for every AI interaction. Only a multilayered approach will ensure true resilience against deepfakes.

Authentication Bypass

Integrating GenAI into enterprise help portals or chatbots can introduce risky login shortcuts. If session or token mechanisms are not robust, a well-crafted prompt can reset or forge access credentials. When AI is invoked within sensitive workflows, it can bypass authentication steps if these are partially automated.

In one observed incident, an internal chatbot linking knowledge bases and HR systems allowed retrieval of employee data without strong authentication, simply by exploiting response-generation logic. Attackers used this vulnerability to exfiltrate address lists and plan spear-phishing campaigns.

To address these risks, strengthen authentication with MFA, segment sensitive information flows, and limit generation and modification capabilities of unsupervised AI agents. Regular log reviews also help detect access anomalies.

The Software Supply Chain Is Weakened by Generative AI

Dependencies on third-party models, open-source libraries, and external APIs can introduce critical flaws into your architectures. Without continuous auditing and control, integrated AI components become attack vectors and compromise your IT resilience.

Third-Party Model Dependencies

Many companies import generic or specialized models without evaluating versions, sources, or update mechanisms. Flaws in an unpatched open-source model can be exploited to insert backdoors into your generation pipeline. When these models are shared across multiple projects, the risk of propagation is maximal.

Poor management of open-source licenses and versions can also expose the organization to known vulnerabilities for months. Attackers systematically hunt for vulnerable dependencies to trigger data exfiltration or supply-chain attacks.

Implementing a granular inventory of AI models, coupled with an automated process for verifying updates and security patches, is essential to prevent these high-risk scenarios.

API Vulnerabilities

GenAI service APIs, whether internal or provided by third parties, often expose misconfigured entry points. An unfiltered parameter or an unrestricted method can grant access to debug or administrative functions not intended for end users. Increased bandwidth and asynchronous calls make anomaly detection more complex.

In one case, an automatic translation API enhanced by an LLM allowed direct queries to internal databases simply by chaining two endpoints. This flaw was exploited to extract entire customer data tables before being discovered.

Auditing all endpoints, enforcing strict rights segmentation, and deploying intelligent WAFs capable of analyzing GenAI requests are effective measures to harden these interfaces.

Code Review and AI Audits

The complexity of language models and data pipelines demands rigorous governance. Without a specialized AI code review process—including static and dynamic analysis of artifacts—it is impossible to guarantee the absence of hidden vulnerabilities. Traditional unit tests do not cover the emergent behaviors of generative agents.

For example, a Basel-based logistics company discovered, after an external audit, that a fine-tuning script contained an obsolete import exposing an ML pod to malicious data corruption. This incident caused hours of service disruption and an urgent red-team campaign.

Establishing regular audit cycles combined with targeted attack simulations helps detect and remediate these flaws before they can be exploited in production.

AI Agents Expand the Attack Surface: Mastering Identities and Isolation

Autonomous agents capable of interacting directly with your systems and APIs multiply intrusion vectors. Without distinct technical identities and strict isolation, these agents can become invisible backdoors.

Technical Identities and Permissions

Every deployed AI agent must have a unique technical identity and a clearly defined scope of permissions. In an environment without MFA or short-lived tokens, a single compromised API key can grant an agent full access to your cloud resources.

A logistics service provider in French-speaking Switzerland, for instance, saw an agent schedule automated file transfers to external storage simply because an overly permissive policy allowed writes to an unrestricted bucket. This incident revealed a lack of role separation and access quotas for AI entities.

To prevent such abuses, enforce the principle of least privilege, limit token lifespans, and rotate access keys regularly.

Isolation and Micro-Segmentation

Network segmentation and dedicated security zones for AI interactions are essential. An agent should not communicate freely with all your databases or internal systems. Micro-segmentation limits lateral movement and rapidly contains potential compromises.

Without proper isolation, an agent compromise can spread across microservices, particularly in micro-frontend or micro-backend architectures. Staging and production environments must also be strictly isolated to prevent cross-environment leaks.

Implementing application firewalls per micro-segment and adopting zero-trust traffic policies serve as effective safeguards.

Logging and Traceability

Every action initiated by an AI agent must be timestamped, attributed, and stored in immutable logs. Without a SIEM adapted to AI-generated flows, logs may be drowned in volume and alerts can go unnoticed. Correlating human activities with automated actions is crucial for incident investigations.

In a “living-off-the-land” attack, the adversary uses built-in tools provided to agents. Without fine-grained traceability, distinguishing legitimate operations from malicious ones becomes nearly impossible. AI-enhanced behavioral monitoring solutions can detect anomalies before they escalate.

Finally, archiving logs offline guarantees their integrity and facilitates post-incident analysis and compliance audits.

Integrating GenAI Security into Your Architecture and Governance

An AI security strategy must cover both technical design and governance, from PoC through production.
Combining modular architecture best practices with AI red-teaming frameworks strengthens your IT resilience against emerging threats.

Implementing AI Security Best Practices

At the software-architecture level, each generation module should be encapsulated in a dedicated service with strict ingress and egress controls. Encryption libraries, prompt-filtering, and token management components must reside in a cross-cutting layer to standardize security processes.

Using immutable containers and serverless functions reduces the attack surface and simplifies updates. CI/CD pipelines should include prompt fuzzing tests and vulnerability scans tailored to AI models. See our guide on CI/CD pipelines for accelerating deliveries without compromising quality, and explore hexagonal architecture and microservices for scalable, secure software.

Governance Framework and AI Red Teaming

Beyond technical measures, establishing an AI governance framework is critical. Define clear roles and responsibilities, model validation processes, and incident-management policies tailored to generative AI.

Red-teaming exercises that simulate targeted attacks on your GenAI workflows uncover potential failure points. These simulations should cover malicious prompt injection, abuse of autonomous agents, and data-pipeline corruption.

Finally, a governance committee including the CIO, CISO, and business stakeholders ensures a shared vision and continuous AI risk management.

Rights Management and Model Validation

The AI model lifecycle must be governed: from selecting fine-tuning datasets to production deployment, each phase requires security reviews. Access rights to training and testing environments should be restricted to essential personnel.

An internal model registry—with metadata, performance metrics, and audit results—enables version traceability and rapid incident response. Define decommissioning and replacement processes to avoid prolonged service disruptions.

By combining these practices, you significantly reduce risk and build confidence in your GenAI deployments.

Secure Your Generative AI with a Proactive Strategy

Confronting the new risks of generative AI requires a holistic approach that blends audits, modular architecture, and agile governance for effective protection. We’ve covered the importance of risk assessment before integration, AI supply-chain control, agent isolation, and governance structure.

Each organization must adapt these principles to its context, leveraging secure, scalable solutions. Edana’s experts are ready to collaborate on a tailored, secure roadmap—from PoC to production.

Cloud vs On-Premise Hosting: How to Choose?

Cloud vs On-Premise Hosting: How to Choose?

Auteur n°16 – Martin

In a context where digital transformation drives the pace of innovation, the choice between cloud and on-premise hosting directly impacts your agility, cost control, and data security. These hosting models differ in terms of governance, scalability, and vendor dependency. The key is to identify the configuration that will optimize your business performance while preserving your sovereignty and long-term adaptability. This article will guide you step by step through this strategic decision, outlining the key criteria, comparing the strengths and limitations of each option, and illustrating with real-world examples from Swiss companies.

Definitions and Deployment Models: Cloud vs On-Premise

Cloud and on-premise embody two diametrically opposed hosting approaches, from infrastructure management to billing. Mastering their characteristics lays the foundation for an architecture that is both performant and resilient.

Deployment Models

The cloud offers an externalized infrastructure hosted by a third-party provider and accessible via the Internet. This model often includes SaaS, PaaS, or IaaS offerings, scalable on demand and billed according to usage. Resources are elastic, and operational management is largely delegated to the provider.

In on-premise mode, the company installs and runs its servers within its own datacenter or a dedicated server room. It retains full control over the infrastructure, from hardware configuration to software patches. This independence, however, requires in-house expertise or an external partnership to administer and secure the environment.

A private cloud can sometimes be hosted on your premises, yet it’s still managed according to a specialized provider’s standards. It offers a compromise between isolation and operational delegation. Conversely, a public cloud pools resources across tenants and demands careful configuration to prevent cross-tenant conflicts.

Each model breaks down into sub-variants: for example, a hybrid cloud combines on-premise infrastructure with public cloud services to address fluctuating needs while securing critical data within the enterprise.

Technical and Architectural Implications

Adopting the cloud drives an architecture firmly oriented toward microservices and APIs, promoting modularity and horizontal scalability. Containers and orchestration (Kubernetes) often become indispensable for automated deployments.

On-premise, a well-optimized monolith can deliver solid performance, provided it’s properly sized and maintained. However, scaling up then requires investment in additional hardware or clustering mechanisms.

Monitoring and backup tools also differ: in the cloud, they’re often included in the service, while on-premise the company must select and configure its own solutions to guarantee high availability and business continuity.

Finally, security relies on shared responsibilities in the cloud, supplemented by strict internal controls on-premise. Identity, access, and patch management call for a robust operational plan in both cases.

Use Cases and Illustrations

Some organizations favor a cloud model to accelerate time-to-market, particularly for digital marketing projects or collaboration applications. Elasticity ensures smooth handling of traffic spikes.

Conversely, critical systems—such as industrial production platforms or heavily customized ERPs—often remain on-premise to guarantee data sovereignty and consistent performance without network latency.

Example: A Swiss manufacturing company partially migrated its production line monitoring to a private cloud while retaining its control system on-premise. This hybrid approach cut maintenance costs by 25% while ensuring 99.9% availability for critical applications.

This case demonstrates how a context-driven trade-off, based on data sensitivity and operational realities, shapes hybrid architectures that meet business requirements while minimizing vendor lock-in risks.

Comparison of Cloud vs On-Premise Advantages and Disadvantages

Each model offers strengths and limitations depending on your priorities: cost, security, performance, and scalability. An objective assessment of these criteria guides you to the most relevant solution.

Security and Compliance

The cloud often provides security certifications and automatic updates essential for ISO, GDPR, or FINMA compliance. Providers invest heavily in the physical and digital protection of their datacenters.

However, configuration responsibility remains shared. Misconfiguration can expose sensitive data. Companies must implement additional controls—key management, encryption, or application firewalls—even in the cloud.

On-premise, end-to-end control ensures physical data isolation, a critical factor for regulated sectors (finance, healthcare). You define access policies, firewalls, and encryption standards according to your own frameworks.

The drawback lies in the operational load: your teams must continuously patch, monitor, and audit the infrastructure. A single incident or overlooked update can cause critical vulnerabilities, highlighting the need for rigorous oversight.

Costs and Budget Control

The cloud promotes low CAPEX and variable OPEX, ideal for projects with uncertain horizons or startups seeking to minimize upfront investment. Pay-as-you-go billing simplifies long-term TCO calculation.

On-premise demands significant initial hardware investment but can lower recurring costs after depreciation. License, hardware maintenance, and personnel expenses must be forecasted over the long term.

A thorough TCO analysis must include energy consumption, cooling costs, server renewals, and equipment depreciation. For stable workloads, five-year savings often outweigh cloud expenses.

Example: A Swiss luxury group compared an IaaS offering to its internal infrastructure. After a detailed audit, it found that on-premise would be 30% cheaper by year three, thanks to server optimization and resource pooling among subsidiaries.

Flexibility and Performance

In the cloud, auto-scaling ensures immediate capacity expansion with resource allocation in seconds. Native geo-distribution brings services closer to users, reducing latency.

However, response times depend on Internet interconnections and provider coverage regions. Unanticipated traffic spikes can incur extra costs or provisioning delays.

On-premise, you optimize internal network performance and minimize latency for critical applications. Hardware customization (SSD NVMe, dedicated NICs) delivers consistent service levels.

The trade-off is reduced elasticity: in urgent capacity needs, ordering and installing new servers can take several weeks.

{CTA_BANNER_BLOG_POST}

Specific Advantages of On-Premise

On-premise offers total control over the technical environment, from hardware to network access. It also ensures advanced customization and controlled system longevity.

Control and Sovereignty

On-premise data remains physically located on your premises or in trusted datacenters. This addresses sovereignty and confidentiality requirements crucial for regulated industries.

You set access rules, firewalls, and encryption policies according to your own standards. No third-party dependencies complicate the governance of your digital assets.

This control also enables the design of disaster recovery plans (DRP) perfectly aligned with your business processes, without external availability constraints.

Total responsibility for the environment, however, demands strong in-house skills or partnering with an expert to secure and update the entire stack.

Business Adaptation and Customization

On-premise solutions allow highly specific developments fully integrated with internal processes. Business overlays and modules can be deployed without public cloud limitations.

This flexibility simplifies interfacing with legacy systems (ERP, MES) and managing complex workflows unique to each organization. You tailor server performance to the strategic importance of each application.

Example: A healthcare provider in Romandy built an on-premise patient record management platform interconnected with medical equipment. Availability and patient data confidentiality requirements necessitated internal hosting, guaranteeing sub-10 millisecond response times.

This level of customization would have been unachievable on a public cloud without significant cost increases or technical limitations.

Longevity and Performance

A well-maintained, scalable on-premise infrastructure can last over five years without significant performance loss. Hardware upgrades are scheduled by the company on its own timeline.

You plan component renewals, maintenance operations, and load tests in a controlled environment. Internal SLAs can thus be reliably met.

Detailed intervention logs, log analysis, and fine-grained monitoring help optimize availability. Traffic peaks are managed predictably, provided capacity is properly sized.

The flip side is slower rollout of new features, especially if hardware reaches its limits before replacement equipment arrives.

Decision Process and Expert Support

A structured approach and contextual audit illuminate your choice between cloud and on-premise. Partner support ensures a controlled end-to-end transition.

Audit and Diagnosis

The first step is inventorying your assets, data flows, and business requirements. A comprehensive technical audit highlights dependencies, security risks, and costs associated with each option.

This analysis covers data volumes, application criticality, and regulatory constraints. It identifies high-sensitivity areas and systems requiring local hosting.

Audit results are presented in decision matrices, weighting quantitative criteria (TCO, latency, bandwidth) and qualitative ones (control, customization).

This diagnosis forms the foundation for defining a migration or evolution roadmap aligned with your IT strategy and business priorities.

Proof of Concept and Prototyping

To validate assumptions, a proof of concept (PoC) is implemented. It tests performance, security, and automation processes in a limited environment.

The PoC usually includes partial deployment on cloud and/or on-premise, integration of monitoring tools, and real-world load simulations. It uncovers friction points and fine-tunes sizing.

Feedback from prototyping informs project governance and resource planning. It ensures a smooth scale-up transition.

This phase also familiarizes internal teams with new processes and incident management in the chosen model.

Post-Deployment Support

Once deployment is complete, ongoing follow-up ensures continuous infrastructure optimization. Key performance indicators (KPIs) are defined to track availability, latency, and costs.

Best-practice workshops are organized for operational teams, covering updates, security, and scaling. Documentation is continuously enriched and updated.

If business evolves or new needs arise, the architecture can be adjusted according to a pre-approved roadmap, ensuring controlled scalability and cost predictability.

This long-term support model lets you fully leverage the chosen environment while staying agile in the face of technical and business changes.

Choosing the Solution That Fits Your Needs

By comparing cloud and on-premise models across security, cost, performance, and control criteria, you determine the architecture best aligned with your business strategy. The cloud offers agility and pay-as-you-go billing, while on-premise ensures sovereignty, customization, and budget predictability. A contextual audit, targeted PoCs, and expert support guarantee a risk-free deployment and controlled evolution.

Whatever your role—CIO, IT Director, CEO, IT Project Manager, or COO—our experts are here to assess your situation, formalize your roadmap, and deploy the optimal solution for your challenges.

Data Sovereignty and Compliance: Custom Development vs SaaS

Data Sovereignty and Compliance: Custom Development vs SaaS

Auteur n°3 – Benjamin

In an environment where data protection and regulatory compliance have become strategic priorities, the choice between SaaS solutions and custom development deserves careful consideration. Swiss companies, subject to the new Federal Data Protection Act (nLPD) and often dealing with cross-border data flows, must ensure the sovereignty of their sensitive information while maintaining agility. This article examines the strengths and limitations of each approach in terms of legal control, technical oversight, security, and costs, before demonstrating why a tailor-made solution—aligned with local requirements and business needs—often represents the best compromise.

The Stakes of Data Sovereignty in Switzerland

Data sovereignty requires strict localization and control to meet the demands of the nLPD and supervisory authorities. Technical choices directly affect the ability to manage data flows and mitigate legal risks associated with international transfers.

Legal Framework and Localization Requirements

The recently enacted nLPD strengthens transparency, minimization, and breach-notification obligations. Companies must demonstrate that their processing activities comply with the principles of purpose limitation and proportionality.

The requirement to store certain categories of sensitive data exclusively within Swiss territory or the European Union can be restrictive. International SaaS providers hosted outside the EU or Switzerland complicate compliance, lacking effective localization guarantees.

With custom development, selecting Swiss-based data centers and infrastructure ensures data remains under local jurisdiction, simplifying audits and exchanges with supervisory authorities.

International Transfers and Contractual Clauses

Standard SaaS solutions often include transfer clauses that may not meet the specific requirements of the nLPD. Companies can find themselves bound by non-negotiable contract templates.

Standard Contractual Clauses (SCCs) are sometimes insufficient or poorly adapted to Swiss particularities. In an audit, authorities demand concrete proof of data localization and the chain of responsibility.

By developing a tailored solution, you can draft a contract that precisely controls subcontracting and server geolocation while anticipating future regulatory changes.

This configuration also makes it easier to update contractual commitments in response to legislative amendments or court rulings affecting data transfers.

Vendor Lock-in and Data Portability

Proprietary SaaS solutions can lock data into a closed format, making future migrations challenging. The provider retains the keys to extract or transform data.

Migrating off a standard platform often incurs significant reprocessing costs or manual export phases, increasing the risk of errors or omissions.

With custom development, storage formats and APIs are defined internally, guaranteeing portability and reversibility at any time without third-party dependence.

Teams design a modular architecture from the outset, leveraging open standards (JSON, CSV, OpenAPI…) to simplify business continuity and minimise exposure to provider policy changes.

Compliance Comparison: Custom Development vs SaaS

Compliance depends on the ability to demonstrate process adherence and processing traceability at all times. The technical approach dictates the quality of audit reports and responsiveness in case of incidents or new legal requirements.

Governance and Internal Controls

In a SaaS model, the client relies on the provider’s certifications and assurances (ISO 27001, SOC 2…). However, these audits often focus on infrastructure rather than organisation-specific business configurations.

Internal controls depend on the configuration options of the standard solution. Some logging or access-management features may be unavailable or non-customisable.

With bespoke development, each governance requirement translates into an integrated feature: strong authentication, contextualised audit logs, and validation workflows tailored to internal processes.

This flexibility ensures full coverage of business and regulatory needs without compromising control granularity.

Updates and Regulatory Evolution

SaaS vendors deploy global updates regularly. When they introduce new legal obligations, organisations may face unplanned interruptions or changes.

Testing and approval cycles can be constrained by the provider’s schedule, limiting the ability to assess impacts on internal rules or existing integrations.

Opting for custom development treats regulatory updates as internal projects, with planning, testing, and deployment managed by your IT team or a trusted partner.

This control ensures a smooth transition, minimising compatibility risks and guaranteeing operational continuity.

Auditability and Reporting

SaaS platforms often offer generic audit dashboards that may lack detail on internal processes or fail to cover all sensitive data processing activities.

Exportable log data can be truncated or encrypted in proprietary ways, complicating analysis in internal BI or SIEM tools.

With custom development, audit reports are built in from the start, integrating key compliance indicators (KPIs), control status, and detected anomalies.

Data is available in open formats, facilitating consolidation, custom dashboard creation, and automated report generation for authorities.

{CTA_BANNER_BLOG_POST}

Security and Risk Management

Protecting sensitive data depends on both the chosen architecture and the ability to tailor it to cybersecurity best practices. The deployment model affects the capacity to detect, prevent, and respond to threats.

Vulnerability Management

SaaS providers generally handle infrastructure patches, but the application surface remains uniform for all customers. A discovered vulnerability can expose the entire user base.

Patch deployment timelines depend on the vendor’s roadmap, with no way to accelerate rollout or prioritise by module criticality.

In custom development, your security team or partner implements continuous scanning, dependency analysis, and remediation based on business priorities.

Reaction times improve, and patches can be validated and deployed immediately, without waiting for a general product update.

Example: A Swiss industrial group integrated a bespoke SAST/DAST scanner for its Web APIs at production launch, reducing the average time from vulnerability discovery to fix by 60%.

Access Control and Encryption

SaaS offerings often include encryption at rest and in transit. However, key management is sometimes centralised by the provider, limiting client control.

Security policies may not allow for highly granular access controls or business-attribute-based enforcement.

With custom development, you can implement “bring your own key” (BYOK) encryption and role-based, attribute-based, or contextual access mechanisms (ABAC).

These choices bolster confidentiality and compliance with strictest standards, especially for health or financial data.

Disaster Recovery and Business Continuity

SaaS redundancy and resilience rely on the provider’s service-level agreements (SLAs). Failover procedures can be opaque and beyond the client’s control.

In a major outage, there may be no way to access a standalone or on-premise version of the service to ensure minimum continuity.

Custom solutions allow you to define precise RPO/RTO targets, implement regular backups, and automate failover to Swiss or multi-site data centers.

Documentation, regular tests, and recovery drills are managed in-house, ensuring better preparedness for crisis scenarios.

Flexibility, Scalability, and Cost Control

TCO and the ability to adapt the tool to evolving business needs are often underestimated in the SaaS choice. Custom development offers the freedom to evolve the platform without recurring license fees or functional limits.

Adaptability to Business Needs

SaaS solutions aim to cover a broad use case spectrum, but significant customization often requires limited configurations or paid add-ons.

Each new requirement can incur additional license fees or extension purchases, with no long-term maintenance guarantee.

With bespoke development, features are built “off-the-shelf” to match exact needs, avoiding bloat or unnecessary functions.

The product roadmap is steered by your organisation, with development cycles aligned to each new business priority.

Hidden Costs and Total Cost of Ownership

SaaS offerings often advertise an attractive monthly fee, but cumulative license, add-on, and integration costs can balloon budgets over 3–5 years.

Migration fees, scale-up charges, extra storage, or additional API calls all impact long-term ROI.

Custom development requires a higher initial investment, but the absence of recurring licenses and control over updates reduce the overall TCO.

Costs become predictable—driven by evolution projects rather than user counts or data volume.

Technology Choice and Sustainability

Choosing SaaS means adopting the provider’s technology stack, which can be opaque and misaligned with your internal IT strategy.

If the vendor discontinues the product or is acquired, migrating to another platform can become complex and costly.

Custom solutions let you select open-source, modular components supported by a robust community while integrating innovations (AI, microservices) as needed.

This approach ensures an evolving, sustainable platform free from exclusive vendor dependency.

Example: A Swiss pharmaceutical company deployed a clinical trial management platform based on Node.js and PostgreSQL, ensuring full modularity and complete independence from external vendors.

Ensure Sovereignty and Compliance of Your Data

Choosing custom development—grounded in open-source principles, modularity, and internally driven evolution—optimally addresses sovereignty, compliance, and security requirements.

By controlling architecture, contracts, and audit processes, you minimise legal risks, optimise TCO, and retain complete agility to innovate.

Cloud, VPS, Dedicated Hosting in Switzerland – Complete Guide

Cloud, VPS, Dedicated Hosting in Switzerland – Complete Guide

Auteur n°2 – Jonathan

In an environment where data sovereignty, operational resilience and regulatory requirements are more crucial than ever, choosing a local hosting provider is a strategic advantage for businesses operating in Switzerland. Hosting cloud, VPS or dedicated infrastructures on Swiss soil ensures not only better performance but also strengthened control over sensitive data, while complying with high security and privacy standards. This comprehensive guide presents the various available offerings, highlights the ethical and eco-responsible challenges—especially through Infomaniak’s model—and provides practical advice to select the hosting solution best suited to your business needs.

Why Host Your Company’s Data in Switzerland?

Hosting in Switzerland provides a strict legal framework and full sovereignty over hosted data. Using a local data center reduces latency and enhances the reliability of critical services.

Data Security and Sovereignty

On Swiss soil, data centers comply with the Federal Act on Data Protection (FADP) as well as ISO 27001 and ISO 22301 standards. This regulatory framework gives organizations optimal legal and technical control over data location and processing. Regular audit mechanisms and independent certifications guarantee full transparency in security and privacy practices. Consequently, the risks of unauthorized transfer or illicit access to information are greatly reduced.

Local operators implement multiple physical and logical protection measures. Access to server rooms is strictly controlled via biometric systems and surveillance cameras, while encryption of data at rest and in transit ensures robustness against intrusion attempts. Isolation of virtual environments into dedicated clusters also limits the spread of potential vulnerabilities between clients. Finally, periodic third-party compliance audits reinforce trust in the infrastructure.

Identity and access management (IAM) policies are often enhanced by privilege-separation mechanisms and cryptographic key encryption. This granularity ensures that only authorized personnel can interact with specific segments of the infrastructure. A full audit trail accompanies this, providing exhaustive tracking of every access event.

Regulatory Compliance and Privacy

Swiss legal requirements for privacy protection are among the strictest in Europe. They include mandatory breach notification and deterrent penalties for non-compliant entities. Companies operating locally gain a competitive edge by demonstrating full compliance to international partners and regulatory authorities.

Geographical data storage rules apply especially in healthcare and finance, where Swiss jurisdiction represents neutrality and independence. Incorporating these constraints from the application design phase avoids downstream compliance costs. Moreover, the absence of intrusive extraterritorial legislation strengthens Swiss organizations’ autonomy over their data usage.

Implementing privacy by design during development reinforces adherence to data minimization principles and limits risks in case of an incident. Integrated compliance audits in automated deployment pipelines guarantee that every update meets legal criteria before going into production.

Latency and Performance

The geographical proximity of Swiss data centers to end users minimizes data transmission delays. This translates into faster response times and a better experience for employees and clients. For high-frequency access applications or large file transfers, this performance gain can be decisive for operational efficiency.

Local providers offer multiple interconnections with major European Internet exchange points (IXPs), ensuring high bandwidth and resilience during congestion. Hybrid architectures, combining public cloud and private resources, leverage this infrastructure to maintain optimal service quality even during traffic spikes.

Example: A Swiss fintech migrated its trading portal to a Swiss host to reduce latency below 20 milliseconds for its continuous pricing algorithms. The result: a 15 % increase in transaction responsiveness and stronger trust from financial partners, without compromising compliance or confidentiality.

Cloud, VPS, or Dedicated Server: Which Hosting Solution to Choose?

The Swiss market offers a wide range of solutions, from public cloud to dedicated servers, tailored to various business needs. Each option has its own trade-offs in terms of flexibility, cost, and resource control.

Public and Private Cloud

Public cloud solutions deliver virtually infinite elasticity through shared, consumption-based resources. This model is ideal for projects with highly variable loads or for development and testing environments. Local hyperscalers also provide private cloud options, ensuring complete resource isolation and in-depth network configuration control.

Private cloud architectures allow deployment of virtual machines within reserved pools, offering precise performance and security control. Open APIs and orchestration tools facilitate integration with third-party services and automated deployment via CI/CD pipelines. This approach naturally aligns with a DevOps strategy and accelerates time-to-market for business applications.

Partnerships between Swiss hosts and national network operators guarantee prioritized routing and transparent service-level agreements. These alliances also simplify secure interconnection of distributed environments across multiple data centers.

Virtual Private Servers (VPS)

A VPS strikes a balance between cost and control. It is a virtual machine allocated exclusively to one customer, with no sharing of critical resources. This architecture suits mid-traffic websites, business applications with moderate configuration needs, or microservices requiring a dedicated environment.

Swiss VPS offerings often stand out with features like ultra-fast NVMe storage, redundant networking, and automated backups. Virtualized environments support rapid vertical scaling (scale-up) and can be paired with containers to optimize resource usage during temporary load peaks.

Centralized management platforms include user-friendly interfaces for resource monitoring and billing. They also enable swift deployment of custom Linux or Windows distributions via catalogs of certified images.

Dedicated Servers

For highly demanding workloads or specific I/O requirements, dedicated servers guarantee exclusive access to all hardware resources. They are preferred for large-scale databases, analytics applications, or high-traffic e-commerce platforms. Hardware configurations can be bespoke and include specialized components such as GPUs or NVMe SSDs.

Additionally, Swiss hosts typically offer advanced support and 24/7 monitoring options, ensuring rapid intervention in case of incidents. Recovery time objective (RTO) and recovery point objective (RPO) guarantees meet critical service requirements and aid in business continuity planning.

Example: A manufacturing company in Romandy chose a dedicated server cluster to host its real-time monitoring system. With this infrastructure, application availability reached 99.99 %, even during production peaks, while retaining full ownership of sensitive manufacturing data.

Ethical and Eco-Responsible Hosting Providers

Ethics and eco-responsibility are becoming key criteria when selecting a hosting provider. Infomaniak demonstrates how to reconcile performance, transparency and reduced environmental impact.

Data Centers Powered by Renewable Energy

Infomaniak relies on a 100 % renewable, locally sourced energy mix, drastically reducing its infrastructure’s carbon footprint. Its data centers are also designed for passive cooling optimization to limit air-conditioning use.

By employing free-cooling systems and heat-recovery techniques, dependence on active cooling installations is reduced. This approach lowers overall power consumption and makes use of waste heat to warm neighboring buildings.

Example: A Swiss NGO focused on research entrusted Infomaniak with hosting its collaborative platforms. As a result, the organization cut its digital estate’s energy consumption by 40 % and gained a concrete CSR indicator for its annual report.

Transparency in Practices and Certifications

Beyond energy sourcing, Infomaniak publishes regular reports detailing power consumption, CO₂ emissions and actions taken to limit environmental impact. This transparency builds customer trust and simplifies CSR reporting.

ISO 50001 (energy management) and ISO 14001 (environmental management) certifications attest to a structured management system and continual improvement of energy performance. Third-party audits confirm the rigor of processes and the accuracy of reported metrics.

Clients can also enable features like automatic idle instance shutdown or dynamic scaling based on load times, ensuring consumption tailored to actual usage.

Social Commitment and Responsible Governance

Infomaniak also embeds responsible governance principles by limiting reliance on non-European subcontractors and ensuring a local supply chain. This policy supports the Swiss ecosystem and reduces supply-chain security risks.

Choosing recyclable hardware and extending equipment lifecycles through refurbishment programs helps minimize overall environmental impact. Partnerships with professional reintegration associations illustrate social commitment across all business dimensions.

Finally, transparency in revenue allocation and investments in environmental projects displays clear alignment between internal values and concrete actions.

Which Swiss Host and Offering Should You Choose?

A rigorous methodology helps select the host and plan that best match your business requirements. Key criteria include scalability, security, service levels and local support capabilities.

Defining Needs and Project Context

Before choosing, it’s essential to qualify workloads, data volumes and growth objectives. Analyzing application lifecycles and traffic peaks helps define a consumption profile and initial sizing.

The nature of the application—transactional, analytical, real-time or batch—determines whether to opt for cloud, VPS or dedicated server. Each option presents specific characteristics in scaling, latency and network usage that should be assessed early on.

Examining software dependencies and security requirements also guides the hosting format. For instance, excluding public third parties in high-risk environments may require a private cloud or an isolated dedicated server.

Technical Criteria and Service Levels (SLA)

The guaranteed availability (SLA) must match the criticality of hosted applications. Offers typically range from 99.5 %, 99.9 % to 99.99 % availability, with financial penalties for downtime.

Incident response times (RTO) and recovery point objectives (RPO) must align with your organization’s interruption tolerance. A local support team available 24/7 is a key differentiator.

Opportunities for horizontal (scale-out) and vertical (scale-up) scaling, along with granular pricing models, help optimize cost-performance ratios. Available administration interfaces and APIs facilitate integration with monitoring and automation tools.

Multi-Site Backups and Redundancy Strategy

A distributed backup policy across multiple data centers ensures data durability in case of a local disaster. Geo-redundant backups enable rapid restoration anywhere in Switzerland or Europe.

Choosing between point-in-time snapshots, incremental backups or long-term archiving depends on data change frequency and storage volumes. Restoration speed and granularity also influence your disaster-recovery strategy.

Finally, conducting periodic restoration tests verifies backup integrity and validates emergency procedures. This process, paired with thorough documentation, forms a pillar of operational resilience.

Secure Your Digital Infrastructure with a Swiss Host

Opting for local hosting in Switzerland guarantees data sovereignty, regulatory compliance and optimized performance through reduced latency. Offerings range from public cloud to dedicated servers and VPS to meet diverse scalability and security needs. Ethical and eco-responsible commitments by providers like Infomaniak help reduce carbon footprints and promote transparent governance. Lastly, a methodical selection approach—incorporating SLAs, load analysis and multi-site redundancy—is essential to align infrastructure with business objectives.

Banking Cybersecurity: Preparing Today for Tomorrow’s Quantum Threat

Banking Cybersecurity: Preparing Today for Tomorrow’s Quantum Threat

Auteur n°2 – Jonathan

As quantum computing approaches practical deployment, today’s encryption methods, once considered robust, are becoming vulnerable. In this context, the banking sector—with its SWIFT, EBICS, SIC SASS networks and multi-year IT investment cycles—must anticipate a major disruption. FINMA 2018/3, FINMA 2023/1 and DORA regulations are increasing pressure on CIOs and CISOs to assess their exposure to “harvest now, decrypt later” and plan a transition to post-quantum cryptography. This article provides an analysis of the risks specific to financial infrastructures and a step-by-step roadmap to manage the quantum threat.

The Stakes of the Quantum Threat for Banking Cryptography

The rise of quantum computing calls into question the security of asymmetric cryptography used by banks. Sensitive traffic—whether transmitted via SWIFT, Open Banking or banking cloud—is now exposed to a future mass-accelerated decryption capability.

Impact on Asymmetric Cryptography

Public-key algorithms like RSA or ECC are based on the difficulty of factorization or the discrete logarithm problem. A sufficiently powerful quantum computer could leverage Shor’s algorithm to reduce these complexities to polynomial time, effectively breaking their security. Keys of 2048 or 3072 bits, considered secure today, would become obsolete once confronted with just a few thousand stable qubits.

In a banking environment where confidentiality and integrity of transactions are paramount, this evolution directly threatens guarantees of non-repudiation and authentication. Electronic signatures, SSL/TLS certificates, and encrypted API exchanges could be compromised.

The vulnerability is not theoretical: malicious actors can already collect and store encrypted traffic for future decryption, as soon as the necessary quantum power is available. This is the so-called “harvest now, decrypt later” strategy, which is particularly concerning for long-lived or regulated data.

The “Harvest Now, Decrypt Later” Phenomenon

In the “harvest now, decrypt later” scenario, an attacker intercepts and stores large volumes of encrypted communications today in anticipation of future quantum capabilities. Once the technology is available, they can retroactively decipher sensitive data, including historical records or archived information.

Banks often maintain transaction archives spanning decades for compliance, audit or reporting purposes. These datasets represent prime targets for future decryption, with serious regulatory and reputational consequences.

The absence of a migration plan to quantum-resistant algorithms therefore exposes financial institutions to risks that cannot be mitigated by late updates, given the lengthy IT project timelines in this sector.

Specific Banking Constraints

Banks operate in a complex ecosystem: SWIFT messaging, ISO20022 standards, EBICS connections, national payment rails like SIC SASS, and Banking-as-a-Service offerings. Each component uses proprietary or shared infrastructures and protocols, making cryptographic overhauls particularly challenging.

Validation cycles, regression testing, and regulatory approvals can span several years. Modifying the cryptographic stack involves a complete review of signing chains, HSM appliances, and certificates, coordinated with multiple partners.

Furthermore, the growing adoption of banking cloud raises questions about key management and trust in infrastructure providers. The quantum migration will need to rely on hybrid architectures, orchestrating on-premise components with cloud services while avoiding vendor lock-in.

Example: A large bank identified all its SWIFT S-FIN and ISO20022 flows as priorities for a quantum assessment. After mapping over 2,000 certificates, it initiated a feasibility study to gradually replace ECC algorithms using nistp-256 with post-quantum alternatives within its HSM appliances.

Assessing Your Exposure to Quantum Risks

Rigorous mapping of critical assets and data flows identifies your quantum vulnerability points. This analysis must encompass SWIFT usage, Open Banking APIs and your entire key lifecycle management, from creation through to archival.

Mapping Sensitive Assets

The first step is to inventory all systems relying on asymmetric cryptography. This includes payment servers, interbank APIs, strong authentication modules, and encrypted data-at-rest databases. Each component must be catalogued with its algorithm, key size and validity period.

This process is based on contextual analysis: an internal reporting module handling historical data may pose a greater risk than a short-lived notification service. Priorities should be set according to business impact and retention duration.

A comprehensive inventory also distinguishes between “live” flows and archives, identifying backup media and procedures. This way, data collected before the implementation of quantum-safe encryption can already be subject to a re-encryption plan.

Analysis of SWIFT and ISO20022 Flows

As SWIFT messages rely on heterogeneous and shared infrastructures, regulatory update timelines apply. Secure gateways such as Alliance Access or Alliance Lite2 may require specific patches and HSM reconfigurations.

For ISO20022 flows, the more flexible data schemas sometimes permit additional signature metadata, facilitating the integration of post-quantum algorithms via encapsulation. However, compatibility with counterparties and clearing infrastructures must be validated.

This analysis should be conducted closely with operational teams and messaging providers, as SWIFT calendars form a bottleneck in any cryptographic overhaul project.

Investment Cycle and Quantum Timeline

Bank IT departments often plan investments over five- or ten-year horizons. Yet, quantum computers with disruptive capabilities could emerge within 5 to 10 years. It is crucial to align the cryptographic roadmap with the renewal cycles of appliances and the HSM fleet.

One approach is to schedule pilot phases as part of the next major upgrade, allocating budget slots for post-quantum PoCs. These initiatives will help anticipate costs and production impacts without waiting for the threat to become widespread.

Planning must also integrate FINMA 2023/1 requirements, which strengthen cryptographic risk management, and DORA obligations on operational resilience. These frameworks encourage the documentation of migration strategies and demonstrable mastery of quantum risk.

{CTA_BANNER_BLOG_POST}

A Progressive Approach to Post-Quantum Cryptography

An incremental strategy based on proofs of concept and hybrid environments limits risk and cost. It combines quantum-safe solution testing, component modularity and team skill development.

Testing Quantum-Safe Solutions

Several families of post-quantum algorithms have emerged: lattice-based (CRYSTALS-Kyber, Dilithium), code-based (McEliece) or isogeny-based (SIKE). Each solution presents trade-offs in key size, performance and implementation maturity.

PoCs can be deployed in test environments, alongside existing RSA or ECC encryption. These experiments validate compatibility with HSM appliances, computation times, and transaction latency impact.

An open and evolving reference framework should guide these trials. It integrates open-source libraries, avoids vendor lock-in and guarantees portability of prototypes across on-premise and cloud environments.
PoC

Hybrid Migration and Modularity

The recommended hybrid architectures use modular encryption layers. A microservice dedicated to key management can integrate a quantum-safe agent without disrupting the main business service. This isolation simplifies testing and scalable rollout.

Using containers and Kubernetes orchestrators enables side-by-side deployment of classical and post-quantum instances, ensuring controlled switchover. APIs remain unchanged, only the encryption connectors evolve.

This approach aligns with an open-source and contextual methodology: each bank adjusts its algorithm catalog based on internal requirements, without hardware or software lock-in.

Proof-of-Concept Management

A quantum PoC involves setting up an isolated environment that replicates critical processes: SWIFT sending and receiving, ISO20022 data exchanges, secure archiving. Teams learn to orchestrate post-quantum key generation, signing and verification cycles.

The PoC enables encryption and decryption volume tests, measurement of CPU/HSM consumption and assessment of SLA impact. Results feed into the business case and the technical roadmap.

This pilot delivers an internal best-practice guide, facilitates regulatory dialogue and reassures senior management about the migration’s viability.

Integration into Your Infrastructures and Regulatory Compliance

Integrating post-quantum cryptography into your systems requires a robust hybrid architecture and adapted governance processes. Compliance with FINMA and DORA standards is a prerequisite for the validity of your transition plan and proof of operational resilience.

Interoperability and Hybrid Architectures

Quantum-safe solutions must coexist with existing infrastructures. The hybrid architecture relies on encryption microservices, PKCS#11-compatible HSM adapters and standardized APIs. Exchanges remain compliant with SWIFT and ISO20022 protocols, while encapsulating the new cryptography.

This modularity decouples cryptographic appliance updates from the application core. Operational teams can manage independent releases, reducing regression risk and accelerating deployment cycles.

Using containers and cloud-agnostic orchestrators enhances scalability and avoids vendor lock-in. Best-in-class open-source tools are favored for encryption orchestration, key management and monitoring.

Meeting FINMA and DORA Requirements

FINMA 2018/3 introduced IT risk management, and Circular 2023/1 increases focus on emerging technologies. Banks must document their exposure to quantum threats and the robustness of their migration strategy.

DORA, currently being implemented, mandates resilience tests, incident scenarios and regular reporting. Including the quantum threat in business continuity and crisis exercises becomes imperative.

Proofs of concept, independent audits and cryptographic risk dashboards are key components of the compliance dossier. They demonstrate control over the transition to quantum-safe and the institution’s ability to maintain critical services.

Monitoring and Continuous Updates

Once deployed, post-quantum cryptography must be subject to ongoing monitoring. Monitoring tools trigger alerts for HSM performance degradation or anomalies in encryption cycles.

Automated regression tests validate new algorithms on each release. Centralized reports track key usage and the evolution of the classical/post-quantum blend, ensuring traceability and visibility for IT steering committees.

Finally, a technology watch program, combined with an open-source community, ensures continuous adaptation to NIST recommendations and advancements in quantum-safe solutions.

Anticipate the Quantum Threat and Secure Your Data

The quantum threat is fundamentally transforming the asymmetric encryption methods used by Swiss and European banks. Mapping your assets, testing post-quantum algorithms and building a contextualized hybrid architecture are key steps for a controlled transition. Integrating FINMA and DORA compliance into your governance ensures resilience and stakeholder trust.

Whatever your maturity level, our experts are by your side to assess your exposure, define a pragmatic roadmap and manage your quantum-safe proofs of concept. Together, let’s build a robust, scalable strategy aligned with your business objectives.

Kubernetes: Why Businesses Need It and How to Use It?

Kubernetes: Why Businesses Need It and How to Use It?

Auteur n°2 – Jonathan

Containerization and microservices orchestration have profoundly transformed how businesses build and maintain their applications. Faced with the growing complexity of distributed architectures, Kubernetes has become the de facto standard for automating deployment and management of large-scale environments. By streamlining scaling, high availability, and resilience, it enables IT teams to focus on innovation rather than operations. In this article, we’ll explore why Kubernetes is essential today, how to adopt it via managed or hybrid offerings, and which organizational and security best practices to anticipate in order to fully leverage its benefits.

Why Kubernetes Has Become the Standard for Modern Application Deployment

Kubernetes provides a unified abstraction layer for orchestrating your containers and managing your services. It ensures portability and consistency across environments, from development to production.

Standardized Containerization and Orchestration

Containerization isolates each application component in a lightweight, reproducible environment that’s independent of the host system. Kubernetes orchestrates these containers by grouping them into Pods, automatically handling replication and placement to optimize resource usage.

Thanks to this standardization, teams can deploy applications identically across different environments—whether development workstations, public clouds, or on-premise clusters—greatly reducing the risk of inconsistencies throughout the lifecycle.

Kubernetes’ labels and selectors mechanism offers a powerful way to target and group workloads based on business criteria. You can apply updates, patches, or horizontal scaling to specific sets of containers without disrupting the entire platform.

Built-in Deployment Automation

Kubernetes includes a deployment controller that natively manages rollouts and rollbacks. You declare the desired state of your applications, and the platform smoothly transitions to that state without service interruptions.

Liveness and readiness probes continuously check container health and automatically shift traffic to healthy instances in case of failure. This automation minimizes downtime and enhances the user experience.

By integrating Kubernetes with CI/CD pipelines, every commit can trigger an automated deployment. Tests and validations run before production rollout, ensuring rapid feedback and more reliable releases.

Extensible, Open Source Ecosystem

Scalable and modular, Kubernetes benefits from a strong open source community and a rich ecosystem of extensions. Helm, Istio, Prometheus, and cert-manager are just a few building blocks that easily integrate to extend core functionality—from certificate management to service mesh.

This diversity lets you build custom architectures without vendor lock-in. Standardized APIs guarantee interoperability with other tools and cloud services, limiting reliance on any single provider.

Kubernetes Operators simplify support for databases, caches, or third-party services by automating their deployment and updates within the cluster. The overall system becomes more coherent and easier to maintain.

For example, a Swiss semi-public services company migrated part of its monolithic infrastructure to Kubernetes, using Operators to manage PostgreSQL and Elasticsearch automatically. In under three months, it cut update time by 40% and gained agility during seasonal demand peaks.

Key Advantages Driving Enterprise Adoption of Kubernetes

Kubernetes delivers unmatched availability and performance guarantees through advanced orchestration. It enables organizations to respond quickly to load variations while controlling costs.

High Availability and Resilience

By distributing Pods across multiple nodes and availability zones, Kubernetes ensures tolerance to hardware or software failures. Controllers automatically restart faulty services to maintain continuous operation.

Rolling update strategies minimize downtime risks during upgrades, while probes guarantee seamless failover to healthy instances without perceptible interruption for users.

This is critical for services where every minute of downtime has significant financial and reputational impacts. Kubernetes empowers the infrastructure layer to deliver robust operational SLAs.

Dynamic Scalability and Efficiency

Kubernetes can automatically adjust replica counts based on CPU, memory, or custom metrics. This horizontal autoscaling capability lets you adapt in real time to workload fluctuations without over-provisioning resources.

Additionally, the cluster autoscaler can add or remove nodes according to demand, optimizing overall data center or cloud usage. You pay only for what you actually need.

This flexibility is essential for handling seasonal peaks, marketing campaigns, or new high-traffic services, while maintaining tight control over resources and costs.

Infrastructure Cost Optimization

By co-hosting multiple applications and environments on a single cluster, Kubernetes maximizes server utilization. Containers share the kernel, reducing memory footprint and simplifying dependency management.

Bin-packing strategies pack Pods optimally, and resource quotas and limits ensure no service exceeds its allocated share, preventing resource contention.

This translates into lower expenses for provisioning virtual or physical machines and reduced operational load for maintenance teams.

For instance, a Geneva‐based fintech moved its critical workloads to a managed Kubernetes cluster. By right-sizing and enabling autoscaling, it cut cloud spending by 25% while improving service responsiveness during peak periods.

How to Leverage Kubernetes Effectively on Managed Cloud and Hybrid Infrastructures

Adopting Kubernetes via a managed service simplifies operations while retaining necessary flexibility. Hybrid architectures combine the best of public cloud and on-premise.

Managed Kubernetes Services

Managed offerings (GKE, EKS, AKS, or Swiss equivalents) handle control plane maintenance, security updates, and node monitoring. This delivers peace of mind and higher availability.

These services often include advanced features like integration with image registries, automatic scaling, and enterprise directory-based authentication.

IT teams can focus on optimizing applications and building CI/CD pipelines without worrying about low-level operations.

Hybrid and On-Premise Architectures

To meet sovereignty, latency, or regulatory requirements, you can deploy Kubernetes clusters in your own data centers while interconnecting them with public cloud clusters.

Tools like Rancher or ArgoCD let you manage multiple clusters from a single control plane, standardize configurations, and synchronize deployments.

This hybrid approach offers the flexibility to dynamically shift workloads between environments based on performance or cost needs.

Observability and Tooling Choices

Observability is crucial for operating a Kubernetes cluster. Prometheus, Grafana, and the ELK Stack are pillars for collecting metrics, logs, and traces, and for building tailored dashboards.

SaaS or open source solutions provide proactive alerts and root-cause analysis, speeding up incident resolution and performance management.

Tooling choices should align with your data volume, retention needs, and security policies to balance cost and operational efficiency.

Anticipating Organizational, Security, and DevOps Best Practices

A successful Kubernetes project goes beyond technology: it relies on DevOps processes and a tailored security strategy. Organization and training are key.

Governance, Organization, and DevOps Culture

Establishing a DevOps culture around Kubernetes requires close collaboration between developers, operations, and security teams. Responsibilities—especially around cluster access—must be clearly defined.

GitOps practices, storing declarative configurations in Git, facilitate code reviews, manifest versioning, and change audits before deployment.

Rituals like configuration reviews and shared operations teams ensure consistent practices and accelerate feedback loops.

Security, Compliance, and Continuous Updates

Kubernetes security demands fine-grained role and permission management via RBAC, workload isolation with Network Policies, and pre-deployment image scanning.

Control plane and node security patches must be applied regularly, ideally through automated processes. Production vulnerabilities should be addressed swiftly to mitigate risks.

Continuous monitoring is essential for meeting regulatory requirements and passing internal audits, especially in banking, healthcare, and industrial sectors.

CI/CD Integration and Deployment Pipelines

CI/CD pipelines orchestrate image builds, unit and integration tests, then deploy to Kubernetes after validation. They ensure traceability and reproducibility of every release.

Tools like Jenkins, GitLab CI, or ArgoCD manage the entire flow from commit to cluster, with automated checks and instant rollback options.

Implementing end-to-end tests and failure-injection drills improves application robustness and prepares teams to handle production incidents.

Optimize Your Infrastructure with Kubernetes

The power of Kubernetes lies in unifying deployment, scaling, and management of containerized applications, while offering open source extensibility and controlled cost management.

Whether you choose a managed service, a hybrid architecture, or an on-premise cluster, the key is to anticipate organizational structure, security, and DevOps processes for successful adoption.

Cloud Migration: What You’re Really Paying (and How to Optimize Your Budget)

Cloud Migration: What You’re Really Paying (and How to Optimize Your Budget)

Auteur n°16 – Martin

Many organizations consider cloud migration simply a cost‐reduction lever. However, bills can quickly become opaque and exceed forecasts, especially when tackling a strategic project without a consolidated view of expenses. Anticipating the different phases, identifying invisible cost items and rigorously governing usage are essential to turn this transition into a sustainable competitive advantage. IT and financial decision-makers must therefore treat cloud migration as a comprehensive undertaking—combining audit, technological adaptation and post-deployment governance—rather than a purely technical shift.

The Three Major Phases of a Cloud Migration and Their Associated Cost Items

A cloud migration is divided into three key stages, each generating direct and indirect costs. Thorough planning from the preparation phase onwards helps curb budget overruns. Mastering these critical cost items is the sine qua non of a project aligned with performance and profitability goals.

Migration Preparation

The preparation phase encompasses auditing existing infrastructure and evaluating the target architecture. This step often engages internal resources as well as external consultants to identify dependencies, map data flows and estimate the required effort.

Beyond the audit, you must budget for training teams on cloud tools and associated security principles. Upskilling sessions can represent a significant investment, especially if you aim to gradually internalize the operation of new platforms.

Finally, developing a migration strategy—single-cloud, multi-cloud or hybrid cloud—requires modeling cost scenarios and anticipated gains. A superficial scoping can lead to late changes in technical direction and incur reconfiguration fees.

Technical Migration

During this stage, the choice of cloud provider directly affects resource pricing (compute instances, storage, bandwidth) and billing models (hourly, usage-based or subscription). Contracts and selected options can significantly alter the monthly invoice.

Adapting existing software—rewriting scripts, containerizing workloads, managing databases—also incurs development and testing costs. Each service to be migrated may require refactoring to ensure compatibility with the target infrastructure.

Engaging a specialized integrator represents an additional expense, often proportional to the complexity of interconnections. External experts orchestrate the decompositions into microservices, configure virtual networks and automate deployments.

Post-Migration

Once the cut-over is complete, operational costs do not vanish. Resource monitoring, patch management and application maintenance require a dedicated organizational setup.

Operational expenditures cover security fees, component updates and ongoing performance optimization to prevent over-provisioning or under-utilization of instances.

Finally, usage governance—managing access, defining quotas, monitoring test and production environments—must be institutionalized to prevent consumption overruns.

Use Case: A Swiss Company’s Cloud Migration

A Swiss industrial SME executed its application migration in three stages. During the audit, it uncovered undocumented cross-dependencies, resulting in a 20% cost overrun in the preparation phase.

The technical migration phase engaged an external integrator whose hourly rate was 30% higher than anticipated due to containerization scripts misaligned with DevOps best practices.

After deployment, the lack of a FinOps follow-up led to systematic over-provisioning of instances, increasing the monthly bill by 15%. Implementing a consumption dashboard subsequently cut these costs by more than half.

Often-Overlooked Costs in Cloud Migration

Beyond obvious fees, several hidden cost items can bloat your cloud invoice. Overlooking them exposes you to untracked and recurring expenses. Heightened vigilance on these aspects ensures budget control and avoids mid-term surprises.

Over-Provisioned Compute Resources

Initial sizing can be overestimated “just in case,” leading to billed servers or containers that are almost idle. Without regular adjustment, these resources become an unjustified fixed cost.

Instances left running after tests and development environments left active generate continuous consumption. This issue is hard to detect without proper monitoring tools.

Without configured autoscaling, manual resizing is time-consuming and prone to human error, occasionally doubling invoices during intensive testing periods.

Forgotten or Under-Utilized Licenses

Many vendors bill licenses per instance or user. When migrating to a new platform, paid features may be activated without measuring their actual usage.

Dormant licenses weigh on the budget without delivering value. It is therefore essential to regularly inventory real usage and disable inactive modules.

Otherwise, new monthly costs from unused subscriptions can quickly undermine server consumption optimization efforts.

Shadow IT and Parallel Services

When business teams deploy cloud services themselves—often through non-centralized accounts—the IT department loses visibility over associated expenses.

These rogue usages generate costly bills and fragment the ecosystem, complicating cost consolidation and the implementation of uniform security policies.

Governance must therefore include a single service request repository and an approval process to limit the proliferation of parallel environments.

Incomplete Migrations and Partial Integrations

A partial migration, with some services remaining on-premise and others moved to the cloud, can create technical friction. Hybrid interconnections incur data transfer and multi-domain authentication fees.

These hidden costs are often underestimated in the initial budget. Maintaining synchronization tools or Cloud-to-OnPremise gateways complicates management and drives operational expenses higher.

In one recent case, a Swiss financial services firm retained its on-premise directory without a prior audit. Connection fees between local and cloud environments resulted in an 18% overrun on the original contract.

{CTA_BANNER_BLOG_POST}

Concrete Cloud Spending Scenarios

Cost trajectories vary widely depending on the level of preparation and the FinOps discipline applied. Each scenario illustrates the impact of organizational and governance choices. These examples help you understand how to avoid overruns and leverage the cloud sustainably.

Scenario 1: Rationalizing a CRM in the Cloud

A company decides to transfer its on-premise CRM to a managed cloud solution. By analyzing usage, it adjusts database sizes and reduces the architecture to two redundant nodes.

By combining reserved instances with on-demand servers during peaks, it halves its total infrastructure cost in the first year.

This success relies on fine-tuned resource management and automated alerts for consumption threshold breaches.

Scenario 2: Unplanned Migration and Budget Drift

Skipping the audit phase leads to a rushed migration. Applications are moved “as-is,” without refactoring, and allocated instances remain oversized.

The monthly cost quickly doubles as unused services continue running and unanticipated data transfer fees appear.

After six months, the organization implements monitoring, makes adjustments and stabilizes spending, but the budget has already suffered a cumulative 40% increase.

Scenario 3: Implementing a FinOps Approach

From project inception, a cross-functional team assigns clear responsibilities among IT, finance and business units. A weekly cost-per-service report is generated automatically.

Optimization processes are established to identify savings opportunities—decommissioning idle volumes, shifting to spot or reserved instances, powering down outside business hours.

Thanks to this governance, operational ROI is achieved in under twelve months without degrading user performance.

How to Control and Optimize Your Cloud Costs?

The combination of a FinOps approach, modular architecture and strict governance is the foundation of budget optimization. These levers enable real-time spending control and resource adjustment according to needs. Guidance from a contextual expert ensures pragmatic implementation aligned with business objectives.

Implement a FinOps Practice

The FinOps approach relies on collecting and allocating costs by functional domain. Implementing summary dashboards enhances visibility and decision-making.

Automated alerts notify you when consumption thresholds are exceeded, allowing immediate instance adjustments or planned scale-ups.

Budget management thus becomes collaborative, making each team accountable for its cloud footprint and fostering a culture of continuous optimization.

Adopt a Modular, Scalable Architecture

The granularity of cloud services—microservices, containers or serverless functions—allows precise sizing. Each component can scale independently.

With orchestration by Kubernetes or a managed service, resources can scale automatically according to load, avoiding any over-provisioning.

Modularity also reduces the risk of a global outage, as an incident on an isolated module does not affect the entire platform.

Train Teams and Govern Usage

The best architecture remains vulnerable if teams lack cloud tool proficiency. A continuous training program and best-practice guides are indispensable.

Defining quotas per project, centralizing requests and systematically approving new services guarantee controlled consumption.

Shared documentation and regular expenditure reviews reinforce transparency and stakeholder buy-in.

Concrete Case: Choosing Comprehensive, Contextual Support

A large Swiss financial enterprise, for example, engaged an expert partner to oversee the entire cloud lifecycle. The approach covered audit, migration, FinOps and post-migration governance.

This collaboration reduced vendor lock-in, optimized storage costs and automated updates while ensuring a high level of security.

After eighteen months, the organization had stabilized spending, improved time-to-market and established a virtuous performance cycle.

Turn Your Cloud Migration into a Strategic Advantage

Cloud migration is not just a cost-reduction lever; it’s an opportunity to rethink your IT architecture and establish a lasting FinOps culture. By anticipating each phase, avoiding hidden expenses and adopting agile governance, you secure your budget and enhance agility.

Guide: Designing an Effective DRP/BCP Step by Step

Guide: Designing an Effective DRP/BCP Step by Step

Auteur n°16 – Martin

The implementation of a Disaster Recovery Plan (DRP) and a Business Continuity Plan (BCP) is a major priority for organizations whose IT underpins their value creation. An uncontrolled outage can cause immediate financial losses, damage customer relationships, and weaken reputation. Yet building a solid DRP/BCP requires combining technical expertise, an understanding of business processes, and anticipation of crisis scenarios. This guide details, step by step, the approach to design a resilience strategy tailored to each context, while highlighting key points of vigilance at each phase. By following these recommendations, you will have a methodological foundation to build a robust and scalable solution.

Understanding DRP and BCP: Definitions and Stakes

The DRP outlines the actions to take after an incident to restore your critical services. The BCP, meanwhile, aims to maintain essential operations continuously during and after a crisis.

What Is a Disaster Recovery Plan (DRP)?

The Disaster Recovery Plan (DRP) focuses on the rapid restoration of systems and data after a major outage or disaster. It defines the technical procedures, responsibilities, and tools needed to resume operations within a predetermined timeframe.

In its most complete form, a DRP covers backup processes, failover to standby infrastructure, and restoration verification. This roadmap often specifies, by scenario, the recovery steps from activation to restoration validation.

Beyond simple restoration, the DRP must ensure the security of restored data to prevent corruption or alteration during production resumption.

What Is a Business Continuity Plan (BCP)?

The BCP complements the DRP by focusing on the continuity of business processes even when primary systems are unavailable. It incorporates workarounds to guarantee a minimum service level, often called the “continuity threshold.”

These may include external services (recovery centers or cloud providers), temporary manual procedures, or alternative applications. The goal is to ensure that priority activities are never completely interrupted.

The BCP also defines operational responsibilities and communication channels during a crisis, to coordinate IT teams, business units, and senior management.

Why These Plans Are Crucial for Companies

In an environment where digital service delivery often drives significant revenue, every minute of downtime translates into direct financial impact and growing customer dissatisfaction.

Regulatory requirements—particularly in financial services and healthcare—also mandate formal mechanisms to ensure critical systems’ continuity and resilience.

Beyond compliance, these plans strengthen organizational resilience, limit operational risks, and demonstrate a proactive stance toward potential crises.

Example: A training center had planned a DRP relying solely on off-site backups without testing restorations. When an electrical failure struck, restoration took over 48 hours, causing critical delivery delays and contractual penalties. They reached out to us, and a full BCP overhaul—including a virtual recovery site and automated failover procedures—reduced the RTO to under two hours.

The Challenges of Implementing a DRP/BCP

Adapting a DRP/BCP to a complex hybrid architecture requires precise mapping of interdependencies between systems and applications. Regulatory and business requirements add further complexity.

Modern IT environments often span data centers, public cloud, and on-premises solutions. Each component has distinct recovery characteristics, making the technical dimension particularly demanding.

A high-level diagram is not enough: it’s essential to delve into data flows, interconnections, and security mechanisms to ensure plan consistency.

This technical complexity must be paired with a deep understanding of business processes in order to prioritize recovery in line with operational and financial stakes.

Complexity of Hybrid Architectures

Organizations combining internal data centers, cloud environments, and microservices must manage availability SLAs that vary widely. Replication and redundancy mechanisms differ depending on the hypervisor, cloud provider, or network topology.

Implementing a DRP requires a detailed vulnerability analysis: Which links are critical? Where should failover points be located? How can data consistency be guaranteed across systems?

Technical choices—such as cross-region replication or multi-zone clusters—must align with each application’s unique recovery requirements.

Regulatory and Business Constraints

Standards like ISO 22301, along with sector-specific regulations (Basel III for banking, cantonal directives for healthcare), often require periodic testing and proof of compliance. Associated documentation must remain up-to-date and comprehensive.

Highly regulated industries demand granular RTO/RPO definitions and restoration traceability to demonstrate the ability to resume operations within mandated timeframes.

These business requirements integrate with operational priorities: tolerated downtime, critical data volumes, and expected service levels.

Stakeholder Coordination

A DRP/BCP’s effectiveness depends on alignment among IT, business teams, operations, and executive management. Project governance should be clearly defined, with a multidisciplinary steering committee.

Every role—from the backup administrator to the business lead ensuring process continuity—must understand their responsibilities during an incident.

Internal and external communications—to clients and suppliers—are integral to the plan to avoid misunderstandings and maintain coherent crisis management.

Key Steps to Plan and Prepare Your DRP/BCP

The design phase relies on a precise risk assessment, an inventory of critical assets, and the definition of recovery objectives. These foundations ensure a tailored plan.

The first step is identifying potential threats: hardware failures, cyberattacks, natural disasters, human error, or third-party service disruptions. Each scenario must be evaluated for likelihood and impact.

From this mapping, priorities are set based on business processes, distinguishing indispensable services from those whose recovery can wait.

This risk analysis enables the establishment of quantitative targets: RTO (Recovery Time Objective) and RPO (Recovery Point Objective), which will drive backup and replication strategy.

Risk and Impact Assessment

The initial assessment requires gathering data on past incidents, observed downtime, and each application’s criticality. Interviews with business stakeholders enrich the analysis with tangible feedback.

Identified risks are scored by occurrence probability and financial or operational impact. This scoring focuses efforts on the most critical vulnerabilities.

The resulting diagnosis also provides clarity on system dependencies, essential for conducting restoration tests without major surprises.

Inventory of Critical Assets

Cataloging all servers, databases, third-party applications, and cloud services covered by the plan is a methodical task that typically uses a CMDB tool or dedicated registry. Each asset is tagged with its criticality level.

It’s also necessary to specify data volumes, update frequency, and information sensitivity, particularly for personal or strategic data.

This asset repository directly informs redundancy architecture choices and restoration procedures: incremental backup, snapshot, synchronous or asynchronous replication.

Defining Target RTO and RPO

RTOs set the maximum acceptable downtime for each service. RPOs define the maximum age of restored data. Each RTO/RPO pairing determines the technical approach: daily backups, daily + continuous backups, or real-time replication.

Setting these objectives involves balancing cost, technical complexity, and business requirements. The tighter the RTO and RPO targets, the more sophisticated the recovery infrastructure and backup mechanisms must be.

A clear priority ranking helps allocate budget and resources, focusing first on the highest impacts to revenue and reputation.

Example: A Swiss retailer defined a 15-minute RPO for its online payment services and a two-hour RTO. This led to synchronous replication to a secondary data center, complemented by an automated failover process tested quarterly.

Deploying, Testing, and Maintaining Your DRP/BCP

The technical rollout integrates backups, redundancy, and automation. Frequent tests and ongoing monitoring ensure the plan’s effectiveness.

After selecting suitable backup and replication solutions, installation and configuration must follow security and modularity best practices. The goal is to evolve the system without a complete rebuild.

Failover (switch-over) and failback (return-to-production) procedures should be automated as much as possible to minimize human error.

Finally, technical documentation must remain up to date and easily accessible for operations and support teams.

Technical Implementation of Backups and Redundancy

Tool selection—whether open-source solutions like Bacula or native cloud services—should align with RTO/RPO targets while avoiding excessive costs or vendor lock-in.

Next, install backup agents or configure replication pipelines, accounting for network constraints, encryption, and secure storage.

A modular design allows replacing one component (e.g., object storage) without redesigning the entire recovery scheme.

Regular Testing and Simulation Exercises

Crisis simulations—including data center outages or database corruption—are scheduled regularly. The goal is to validate procedures and team coordination.

Each exercise ends with a formal report detailing gaps and corrective actions. These lessons feed the plan’s continuous improvement.

Tests also cover backup restoration and data integrity verification to avoid unwelcome surprises during a real incident.

Monitoring and Plan Updates

Key metrics (backup success rates, failover times, replication status) should be monitored automatically. Proactive alerts enable rapid correction of issues before they threaten the DRP/BCP.

An annual plan review, combined with updates to risk and asset registries, ensures the solution stays aligned with infrastructure changes and business requirements.

Maintaining the plan also involves ongoing team training and integrating new technologies to enhance performance and security.

Turn Your IT Infrastructure into a Sustainable Advantage

A well-designed DRP/BCP rests on rigorous risk analysis, accurate critical-asset mapping, and clear RTO/RPO objectives. Technical implementation, regular testing, and automated monitoring guarantee plan robustness.

Every organization has a unique context—business needs, regulatory constraints, existing architectures. It’s this contextualization that separates a theoretical plan from a truly operational strategy.

Edge Computing: Serving as Close as Possible to the User

Edge Computing: Serving as Close as Possible to the User

Auteur n°14 – Daniel

The exponential growth of connected devices and the widespread adoption of 5G are fundamentally reshaping IT architectures. To meet stringent latency, bandwidth, and sovereignty requirements, processing can no longer always flow through a centralized cloud. Edge computing offers a pragmatic solution: process and analyze data as close as possible to its source, where it’s generated. This hybrid approach combines agility, robustness, and security, while equipping businesses to leverage new real-time services.

Understanding Edge Computing and Its Foundations

Edge computing shifts processing closer to data sources to reduce latency and optimize bandwidth. It leverages edge servers, microservices, and modular components to deliver local performance without relying on a centralized cloud.

Definition and Key Principles

Edge computing involves running IT services on equipment located at the network’s edge, near sensors, IoT devices, or business terminals. The goal is to minimize dependence on remote data centers and cut processing delays.

This distribution of workloads relies on nodes known as “edge nodes” or “edge servers,” capable of hosting microservices, containerized functions, or AI algorithms. Each node operates autonomously and can synchronize its results with a cloud or central data center.

By using open-source technologies like Kubernetes or Docker, organizations ensure maximum modularity and portability. New services can be deployed without risk of vendor lock-in, guaranteeing a seamless evolution of the IT ecosystem.

Architectures and Essential Components

A typical edge architecture includes sensors, IoT devices, edge servers, and one or more cloud consolidation points. Sensors collect raw data, edge nodes perform initial filtering and preprocessing, and relevant insights are then forwarded to the cloud for deeper analysis.

Software components are usually packaged as lightweight microservices, orchestrated by container platforms. This model enables horizontal scalability and fault isolation, with each service redeployable independently.

Edge nodes can be hosted in industrial facilities, operator boxes, or dedicated micro-data centers. They employ advanced security mechanisms (encryption, mutual authentication, microsegmentation) to protect sensitive data from the point of capture.

Comparison with Traditional Cloud

Unlike public cloud environments—where all processing occurs in centralized data centers—edge computing prioritizes proximity. This distinction dramatically reduces latency, often by a factor of ten or twenty, and conserves bandwidth by avoiding continuous transmission of massive data volumes.

The cloud still plays a strategic role for long-term storage, global data aggregation, and large-scale AI model training. Edge computing doesn’t replace the cloud; it extends its capabilities by intelligently distributing workloads.

For example, a Swiss pharmaceutical company deployed edge gateways to analyze air quality and production flows in its clean rooms in real time. This setup cut false alerts by 65% while maintaining regulatory compliance.

Meeting the Demands of Critical Environments

Edge computing excels where near-zero latency and maximum availability are essential. It addresses bandwidth, sovereignty, and resilience requirements in sectors such as Industry 4.0, retail, and healthcare.

Low Latency for Industry 4.0

In smart factories, every millisecond counts for production line control and defect prevention. Edge computing processes data locally from programmable logic controllers and sensors, ensuring real-time control loops.

Machine learning algorithms can be deployed at the edge to automatically detect anomalies without waiting for cloud processing. This responsiveness prevents costly production halts and improves product quality.

A modular approach simplifies system upgrades: each new algorithm version is distributed as an independent container. Teams benefit from rapid deployment cycles and streamlined maintenance.

Service Continuity in Connected Retail

For multi-site retailers, edge computing ensures critical applications remain available even during network outages. Point-of-sale and inventory systems continue functioning without relying on the central data center.

Edge nodes store and sync customer and inventory data locally, then replicate updates to the cloud once connectivity is restored. This hybrid model prevents revenue losses from downtime and enhances the user experience.

By processing sensitive data at the edge, retailers also meet data sovereignty and protection requirements without relying exclusively on external data centers.

Sovereignty and Security in Healthcare

Hospitals and clinics must comply with stringent privacy regulations. Edge computing enables sensitive medical data to be processed directly on-premises, without transferring it to uncertified external infrastructures.

Medical images, vital signs, and patient records can be analyzed locally via edge servers, reducing the risk of data breaches and ensuring continuous availability during network incidents.

A hospital in French-speaking Switzerland adopted this solution for its MRI scanners. Initial diagnoses are performed on site, and aggregated data is then sent to the institution’s secure cloud for archiving and specialist collaboration.

Seamless Integration with Cloud and Hybrid Architectures

Edge computing complements cloud and hybrid environments rather than replacing them. It enables intelligent, local data processing while leveraging the power and flexibility of public or private clouds.

Hybrid Integration Scenarios

Multiple models coexist based on business needs. In a “cloud-first” scenario, the central cloud orchestrates deployments and data consolidation, while edge nodes handle local preprocessing and filtering.

Conversely, an “edge-first” approach prioritizes edge processing, with the cloud serving as backup and aggregation. This configuration suits environments with intermittent connections or strict bandwidth constraints.

Hybrid architectures provide the agility to tailor data processing to operational contexts, while ensuring disaster recovery and service redundancy.

Modularity and Microservices at the Edge

Fragmentation into microservices makes each component independent, simplifying updates and scaling. Edge nodes deploy only the services required for their use cases, reducing the software footprint.

Security and functional updates can be orchestrated granularly via CI/CD pipelines. This ensures each component stays up to date without redeploying the entire infrastructure.

By combining proven open-source modules with custom developments, each deployment remains contextual and aligned with business objectives, avoiding excessive dependencies.

Distributed Data Management

Data can be partitioned across multiple edge sites, then synchronized using asynchronous or event-driven replication. This ensures sufficient consistency while maximizing resilience.

Microsegmentation and encrypted data flows protect information in transit. Keys can be managed locally to meet sovereignty requirements.

A Swiss logistics company deployed edge nodes to process transport orders in real time. Stock levels are first updated locally, then batched to the cloud—optimizing performance without sacrificing reliability.

Boosting System Agility, Robustness, and Autonomy

Edge computing delivers enhanced operational agility, resilience to failures, and local processing autonomy. These benefits translate into accelerated innovation and reduced IT risk.

Operational Responsiveness

By bringing processing closer to devices, reaction times to critical events become virtually instantaneous. Process adjustments or automated actions execute with imperceptible delay.

This speed enables faster service rollouts and more effective responses to demand shifts or technical contingencies.

Operations teams gain access to more responsive tools and real-time feedback, fostering confidence in systems and freeing resources for innovation.

Enhanced Security and Data Control

Processing sensitive data on localized nodes minimizes attack surfaces. Critical data flows traverse fewer external network segments, reducing compromise risks.

Automated update and patching processes ensure each edge node remains protected against known vulnerabilities.

A hybrid approach allows organizations to apply encryption and governance policies compliant with each jurisdiction’s regulations while maintaining centralized visibility.

Scalability and Optimized Resource Utilization

Edge nodes can be precisely sized according to location and expected load. This granularity ensures compute and storage capacity align with needs, avoiding massive overprovisioning.

Horizontal scaling permits dynamic node additions or removals based on seasonality, traffic peaks, or one-off requirements.

Modular open-source architectures combined with automated pipelines deliver optimized operations, cutting OPEX and simplifying long-term maintenance.

Edge Computing: Catalyze Your Operational Efficiency

Deploying an edge architecture delivers low latency, resilience, and data control, while integrating seamlessly with public and private clouds. Businesses gain agility and autonomy, reduce downtime risks, and future-proof their infrastructure for real-time use cases.

How NGOs and International Organizations Can Secure Their Data

How NGOs and International Organizations Can Secure Their Data

Auteur n°3 – Benjamin

NGOs and international organizations handle extremely sensitive information every day: medical data, geographic coordinates of vulnerable populations, religious or political affiliations. Yet 86% of them lack a formal cybersecurity plan, exposing this data to major risks. In the face of growing targeted attacks, it is imperative to quickly adopt a structured approach, even with limited resources. This article offers concrete priorities for securing your critical assets and explains how a specialized partnership can provide an adaptable, scalable framework aligned with field realities and regulatory requirements.

NGOs: Easy Targets with Critical Stakes

Humanitarian organizations hold highly sensitive and strategic data. Cybercriminals perceive them as vulnerable targets.

Stakes of Sensitive Data

NGOs manage personal information related to identity, health, location, or ideological affiliations of populations in fragile situations. Any data leak or manipulation can endanger beneficiaries’ lives and damage the organization’s credibility.

Donors and partners expect rigorous protection of financial data, whether it concerns bank transfers or mobile payments in unstable zones. A breach can lead to direct financial losses and shatter international trust.

The absence of a security framework also exposes field staff to retaliation. If their contact details or incident reports are disclosed, they can become targets of hostile groups.

Perception of Weak Targets

Many NGOs operate with tight budgets and often limited IT resources, reinforcing the idea that they lack adequate protection. This perception encourages attackers to favor these organizations over better-equipped corporate entities.

Cybercriminals employ phishing techniques tailored to the humanitarian sector, posing as donors or funding agencies. These methods exploit the natural trust placed in messages related to charitable causes.

State-sponsored hacker groups also exploit these vulnerabilities to gather intelligence. NGOs working in geopolitically sensitive areas are particularly targeted, as their information is valuable for intelligence operations.

Consequences of a Breach

If unauthorized access occurs, database manipulation can cause beneficiaries to flee, fearing for their safety, thus undermining humanitarian program effectiveness. Vulnerable populations are then deprived of vital support.

Major security incidents can lead to regulatory investigations and sanctions, especially when NGOs process data of European citizens and may be subject to the nLPD and GDPR. The financial and legal stakes become considerable.

For example, a hypothetical Geneva-based association was hit by ransomware that paralyzed its beneficiary management system for a week. Extended response times delayed emergency aid distribution and incurred several tens of thousands of francs in recovery costs.

Map and Classify Sensitive Data

The first step is to inventory all flows and locations of your critical information. This mapping allows you to adjust protection levels according to sensitivity.

Inventory of Systems and Flows

You need to take stock of applications, databases, and file exchanges. Every channel must be identified, from field collection to cloud storage or internal servers.

Details include users, access profiles, and external connections. This overview helps spot outdated configurations or practices that don’t meet security best practices.

One public-health NGO discovered unencrypted file shares between its local office and overseas collaborators. This lack of encryption exposed detailed medical reports.

Classification by Criticality

Once data is located, define sensitivity levels: public, internal, confidential, or strictly secret. This categorization guides the choice of protection measures to apply.

Donor and beneficiary banking data are classified as “strictly secret,” requiring strong encryption and enhanced access controls. External communication documents can remain at the “internal” level.

Classification should be dynamic and regularly reviewed, especially after organizational changes or the addition of new systems.

Dynamic Mapping and Regular Review

Beyond a one-off inventory, mapping must evolve with changes: new applications, partner integrations, or modifications in business processes. Continuous monitoring helps anticipate risks.

Open-source tools can automate detection of newly exposed services and generate evolution reports. This approach minimizes manual work and reduces blind spots.

Mapping also serves as the basis for targeted penetration tests (pentests), validating the real-world robustness of defenses.

Implement Essential Basic Protections

Several elementary, often low-cost measures provide significant security. They form the foundation of any cybersecurity strategy.

Strong Authentication and Access Management

Deploying MFA (multi-factor authentication) drastically reduces the risk of critical account takeover, even if passwords are compromised. This measure is simple to enable on most systems.

It’s essential to limit rights to the actual needs of each role: the principle of least privilege. Administrator accounts should be dedicated and reserved for maintenance or configuration tasks.

For example, a Swiss para-public institution implemented quarterly user rights reviews. This process immediately removed over 60 inactive accounts with elevated privileges.

Securing Data in Transit and at Rest

Encrypting databases and cloud storage prevents unauthorized access to sensitive files. TLS/HTTPS protocols protect Internet exchanges, and VPNs secure inter-office links.

DLP (Data Loss Prevention) solutions can identify and block the exfiltration of critical data via email or file transfer. They provide real-time filtering and alerts for suspicious behavior.

These often open-source tools integrate into modular architectures without vendor lock-in and can scale with organizational growth.

Password Policy and Pseudonymization

A strict policy enforces strong passwords, regular rotation, and prohibits reuse. Centralized password management tools simplify compliance with this policy.

Pseudonymizing critical data separates real beneficiary identifiers from processing files. This technique limits the impact of a breach and directly draws on nLPD and GDPR guidelines.

The combination of strong authentication, systematic encryption, and pseudonymization provides a robust barrier against internal and external threats.

Deploy a Proportional and Progressive Strategy

Protection should be tailored to data criticality and integrated from system design. A phased plan ensures concrete, achievable actions.

Security by Design and Modularity

Embedding cybersecurity into the design phase avoids extra costs and unreliable workarounds. The architecture should be modular, favoring proven open-source building blocks.

Microservices can segment critical functions, limiting the impact of a compromise to a restricted perimeter. Integrating secure containers further reinforces component isolation.

This contextual approach aligns with Edana’s philosophy: no one-size-fits-all recipe, but choices adapted to each use case.

Framework Inspired by nLPD and GDPR

Data protection regulations propose a clear methodology for managing personal data: processing registers, impact analyses, explicit consent, and the right to be forgotten. NGOs can apply these best practices to all their sensitive data.

Even if some organizations have no direct legal obligation, referring to European standards demonstrates rigor and eases compliance in international partnerships.

This framework provides a reference to define governance processes and risk-tracking indicators.

Progressive Approach with a Specialized Partner

Even with limited means, you can plan priority projects in the short, medium, and long term. An initial security audit identifies high-impact immediate actions and future investment needs.

A specialized partner can bring proven methodology, open-source tools, and targeted training for IT teams and compliance officers. This support is delivered in successive cycles, adapted to budgetary constraints.

Gradually building internal team expertise ensures growing autonomy and the sharing of best practices within the organization.

Protect Your Data, Safeguard Your Mission

Securing sensitive data is not a luxury but a sine qua non to ensure the sustainability and impact of NGOs and international organizations. By identifying, classifying, and locating your critical information, you can apply high-yield basic measures, then develop a proportional, resilient strategy.

These actions, aligned with a clear framework and deployed progressively with an expert partner, ensure robust protection while remaining feasible with limited resources.
