Sovereign cloud: data, keys and operations under your own jurisdiction
The sovereign cloud is a cloud offering designed to guarantee that data, encryption keys and operations remain under a specific jurisdiction —usually the EU— and isolated from foreign access, with local governance and operation. It addresses data residency, protection against extraterritorial legislation and digital sovereignty, all increasingly present in banking, insurance and the public sector.
What it guarantees
- Data residency — data is stored and processed within the required jurisdiction, with no replicas outside it.
- Key control — the institution or a local third party holds the encryption keys, so the provider cannot decrypt the data.
- Local operation — administration and support by staff subject to the applicable law, with no access from outside the jurisdiction.
- Legal isolation — contractual and technical barriers against requests from foreign authorities.
Why it matters in banking and insurance
The risk the sovereign cloud addresses is extraterritorial access: third-country legislation that can compel a provider to hand over data hosted on its infrastructure, even if that data is physically in the EU. For a financial institution that is direct regulatory and reputational exposure. Within the DORA framework, the sovereign cloud is also a response to concentration risk: it reduces dependence on hyperscalers outside the jurisdiction and strengthens the ability to demonstrate control over critical data.
