Sovereign Cloud Is Not a Sticker – It’s a Structural Choice

As digital sovereignty gains momentum in Europe — with political urgency and new procurement demands — more and more vendors are claiming to offer a “sovereign cloud.” But what does that actually mean? When is a cloud truly sovereign, and when is it just marketing?

At Soverin, we believe sovereignty should be measurable. So we created a simple benchmark with 10 critical questions — covering data location, legal control, open standards, transparency, and the ability to exit freely.

Here’s the Sovereign Cloud Checklist, with Soverin’s position filled in:

Category	Key Question	Soverin
Data Location	Are all data stored physically in Europe?	Yes – Netherlands-based
Jurisdiction	Is the full infrastructure governed by EU law (no CLOUD Act exposure)?	Yes – Fully EU-owned and operated
Open Standards	Does it use open protocols (IMAP, SMTP, etc.) and avoid vendor lock-in?	Yes – 100% open standards
Stack Transparency	Can customers inspect or audit the stack?	Yes – Built on open components
Data Ownership	Does the customer retain full control over their data and identity?	Yes – Customer-owned, no lock-in
Identity Infrastructure	Is identity/authentication managed under European control?	Yes – Fully European stack
Interoperability	Is it easy to migrate out using standard tools?	Yes – Migration and export tools
Accessibility	Is it suitable for public sector and SMEs without complex dependencies?	Yes – Simple service, also white-label
Policy Alignment	Is it aligned with EU policy (Data Act, SECA, EuroStack)?	Yes – Active supporter of EuroStack
Sustainability	Does it run on green, energy-efficient infrastructure?	Yes – Green-powered data centers

What We’re Seeing in the Market

Many vendors fall short once we ask the tough questions — especially about:

• Legal jurisdiction (are you really outside the reach of the CLOUD Act?),

• Identity services (can you control your digital keys independently?),

• or Exit options (can you actually leave without rebuilding?).

Where Soverin Stands

At Soverin, we don’t outsource sovereignty. We build for it:

• Our infrastructure is 100% European.

• We use open standards and interoperable formats.

• Customers own their data, identities, and communications.

We focus on email and identity — two core layers of any cloud infrastructure that often get overlooked. But they matter most. Because without sovereign communication, there is no sovereign cloud.

Sovereignty isn’t a sticker. It’s a structural choice.

Ask your provider these 10 questions. If they can’t answer clearly — they may not be as sovereign as they claim.
