For years, digital sovereignty was treated as a political issue. It has now become an operational matter: where is the data stored, who can access it, under which jurisdiction, and according to what technical guarantees?

A subject that now affects all organisations

  • administrations that must guarantee non-accessibility by foreign jurisdictions;
  • healthcare providers subject to HDS;
  • financial operators subject to DORA;
  • essential entities as defined by NIS2;
  • exporting mid-caps (ETIs), subject to increasingly stringent contractual constraints.

The false comfort of hyperscale platforms

Storing data with a global cloud provider can create a sense of security. But it guarantees neither legal sovereignty nor control over data history or the ability to reproduce a past state.

Sovereignty is not merely a question of location: it is also a question of control.

The pillars of truly controlled data

  • the choice of S3 storage (sovereign, hybrid, or cloud);
  • encryption managed by the organisation;
  • provider-independent historisation;
  • unrestricted data export;
  • the absence of vendor lock-in.

KARL and practical sovereignty

KARL is designed to operate on the leading S3 implementations — whether sovereign, on-premise, or international cloud — without relying on an intermediate database or a third-party service.

This approach allows each organisation to freely choose its infrastructure while maintaining the same level of traceability, immutability, and resilience.

Sovereignty becomes what it should have always been: a choice, not a constraint.
