What is data sovereignty?

Data sovereignty is about an organisation keeping control of its data, including which laws apply to it and who can gain access to it.

Where data is stored decides which laws apply. But the location is not always enough. A supplier can be subject to another country's laws even when its servers are in Sweden.

So data sovereignty is also about who operates the system, which sub-suppliers are involved and which authorities can demand access to the data.

For the public sector and organisations with confidentiality requirements the question has become more important. It affects which cloud services can be used for which information.

In May 2026 the Swedish government adopted a cloud policy for public administration aimed at greater digital sovereignty. It stresses control over data, fewer dependencies and the ability to change supplier.

How it works

In practice, data sovereignty is tested at several points: where the data is stored and processed, who operates the system and which subcontractors have access. At each point it matters which country's laws apply. A solution in your own environment has fewer points to examine than a service with many subcontractors.

Why it matters

AI makes the question more pressing, because an assistant often reads the most valuable material, such as contracts, cases, personal data and strategic documents. For the public sector it can also involve public access and confidentiality rules, and whether disclosing data to a provider is compatible with them.

Laws that reach beyond a country's borders, such as the CLOUD Act, mean the storage location alone does not decide. That is why extraterritorial law has become part of the same assessment, including for AI services that pass questions on to another provider.

What to keep in mind

Data sovereignty is about more than geography. It also covers what happens when the contract ends, whether data can be exported and deleted, and whether the service keeps working if the provider disappears.

There are two common routes: running AI in your own environment or choosing a provider that runs a separate environment per customer and can show where everything is.

What it means for you

Ask the supplier which countries' laws apply to it, to its sub-suppliers and to its operations.

Common questions

Is it enough for data to be stored in the EU?

Not always. If the supplier is subject to another country's laws, authorities there may in some cases demand access to data. Both storage location and who controls the supplier matter.

How do we keep control when using AI?

Find out where data is processed and who can reach it. The most direct route is to run AI in your own environment.

Is a sovereign cloud the same as data sovereignty?

A sovereign cloud is one way to strengthen data sovereignty, with operations and staff in the EU. It still makes sense to ask who owns the company behind it, since the CLOUD Act turns on control.
