Digital sovereignty & data residency

Digital sovereignty means deciding yourself where data lives, who can access it and how replaceable providers are.

Digital sovereignty is the ability of companies and states to decide self-determinedly about their digital systems and data: where data is processed (data residency), which jurisdiction it falls under, how dependent you are on individual providers — and how quickly you could switch.

The topic has moved from political debate into procurement reality: customers, regulation and risk management increasingly ask about processing locations, third-country access possibilities and exit scenarios.

The building blocks of sovereign architectures

Data residency is the most tangible lever: EU processing regions, regional services features that confine traffic processing to EU locations, and metadata controls ensure data does not leave the chosen jurisdiction. Add encryption with your own key control and contracts under European law.

Equally important is the dependency question: open standards and interoperability instead of proprietary formats, documented exit strategies, multi-provider capability — sovereignty is measured by how realistic a switch would be, not by whether you plan one. Complete autarky is rarely the goal; managed, conscious dependency is the realistic ambition.

Assessing sovereignty practically

Know processing locations per service — including support access and metadata.
Check the providers’ jurisdiction: which authorities can demand which access?
Key control: who can decrypt — only you or the provider too?
Test exit capability: data export, format openness, parallel operation.

Frequently asked questions about Digital sovereignty & data residency

What does data residency mean concretely?

Determining in which countries or regions data is stored and processed. Modern cloud platforms offer region selection and features such as regional services that also confine the processing of traffic and metadata to defined locations.

Is sovereignty the same as a European provider?

No — origin is only one factor. What decides are processing locations, jurisdiction, key control, contract design and switchability. A global provider with EU processing, customer key control and a clean exit can be more sovereign than a local one without all that.

What role does encryption play for sovereignty?

A central one: whoever controls the keys controls access — regardless of storage location. Customer-managed keys and end-to-end encryption reduce the ability of providers and third parties to view content to the technically necessary.

How does digital sovereignty relate to NIS2 and DORA?

Both regimes demand risk management for dependencies: DORA explicitly addresses ICT third-party risk in the financial sector, NIS2 the security of the supply chain. Processing locations, exit strategies and provider assessments are thus compliance artefacts too.

What is a realistic first step?

Transparency: a register of services with processing locations, jurisdiction and degree of dependency — prioritised by criticality. The levers follow from it: activate EU regions, increase key control, document exit scenarios for the most critical services.
