Faced with increasingly sophisticated ransomware attacks, infrastructure outages and global geopolitical tensions, resilience has become a priority for executive committees. Yet one major gap remains in many business continuity plans (BCPs): the absence of digital sovereignty.
Designing for resilience without incorporating sovereignty is like building a vault whose key belongs to a third party. If a political event or an extraterritorial law blocks access to your infrastructure, your data — even if it remains intact — becomes inaccessible.
To avoid this trap, here is a practical roadmap for placing sovereignty at the heart of your resilience strategy.
Step 1: Map and classify your data by criticality
Trying to protect everything to the same level is both an economic and operational mistake. The first step is to identify where your organisation's most vital value lies.
-
The “masterpiece” principle: Just as you would protect a masterpiece differently from the rest of your furniture, you need to isolate your ultra-critical data, including customer files, intellectual property, accounting records and payroll systems. These assets underpin your sovereignty.
-
The durability assessment: Evaluate how well your current systems can withstand physical failure or the silent degradation of hard drives, known as bit rot. Require your providers to make a clear, measurable commitment regarding data durability.
Step 2: Audit the legal and human dependencies across your ecosystem
Overall business resilience depends not only on your own servers, databases and applications, but also on your entire interconnected ecosystem.
Legal dependency and extraterritoriality
Requiring your data to be physically located in a data centre in France is not enough if the operator is a subsidiary of a group subject to the US CLOUD Act. Your audit must confirm that your partner's code, infrastructure and ownership structure are governed exclusively by European law.
Human dependency and technology choices
Avoid building your resilience on highly complex, “raw” open-source solutions with no vendor support. If two or three key people leave your IT department, you may lose control of your systems. Give preference to Open Composability — open, transparent and transferable code — backed by a sovereign partner capable of ensuring continuity of expertise.
Step 3: Deploy the technical triad of sovereign backup
To ensure that neither a hacker nor an external geopolitical decision can paralyse your recovery operations, your storage architecture must incorporate three fundamental security safeguards, ideally operated in partnership with trusted providers:
-
Immutability (S3 Object Storage): Your backups are locked. Even in the event of a major intrusion involving privilege escalation, an attacker cannot alter or delete your data.
-
Air Gap: A second copy of your data is stored in a completely sealed and isolated environment that is invisible from your primary network.
-
Green Room (recovery environment): In a crisis, you must be able to rapidly rebuild your critical applications — such as payroll or sales management — on dedicated, sovereign and ready-to-use cloud infrastructure.
Step 4: Protect data processing in the age of AI
Artificial intelligence is profoundly transforming resilience. It is both a powerful ally — capable of analysing backup volumes to detect dormant malware before restoration — and a new attack vector.
However, integrating AI into your resilience strategy requires even greater vigilance regarding sovereignty. If strategic business data is sent for processing by non-sovereign AI algorithms, you lose control of your intellectual property. Tomorrow's sovereignty will depend not only on where data is stored, but also on where it is processed.
Step 5: Move from theory to crisis exercises
A business continuity plan that is merely written down and stored in a workspace will be of no use if, when a crisis occurs, no one knows where to find it, how to contact external partners or which actions must be taken and prioritised in coordination with the organisation's business teams.
-
Immersive role-playing: Bring executive management, IT and business teams together for two to three hours. Define a realistic scenario inspired by a current cyber threat and test how effectively everyone responds.
-
Employee training: Every employee should receive pragmatic training in essential response procedures. How should they handle a suspicious email? What should they do if their collaboration platform suddenly becomes unavailable?
Sovereignty as a driver of growth
To keep creating value, organisations must also protect the assets that generate that value from destruction. Integrating sovereignty into your resilience strategy is no longer simply a regulatory obligation — such as complying with the requirements of the NIS2 Directive or DORA — but a winning business strategy. It is how you assure customers, employees and shareholders that your organisation remains in control of its technological future and can withstand both cyber crises and geopolitical storms.
