EU Data Sovereignty: Now Available at Ardoq

Written by Nicholas Boyd | Oct 27, 2026, 2:55:05 PM

Ardoq now offers EU data sovereignty as an option for organizations that need it: hosting on an EU-owned sovereign cloud, built for teams that need their enterprise architecture data under European legal control, not just stored on European soil. It sits alongside our existing EU hosting on AWS and Azure, so you choose what fits your requirements. Here is what is live, what it covers, and how to talk to us about it.

Sovereignty Is Becoming a Buying Requirement

Control over data is a boardroom concern, not just an IT one. Across Europe, public sector organizations are increasingly expected to run software on locally owned clouds rather than on infrastructure controlled by non-EU providers. The driver is geopolitical: unease about how much leverage foreign governments hold over the platforms that run critical systems.

It no longer stops at government. Financial services, insurance, and other highly regulated industries are asking the same question: whose laws govern our data?

"Customers used to ask where their data lives. Now they ask whose laws apply to it. With EU data sovereignty, we can answer that directly."

Bo Kristoffersen, VP of Sales, EU

Residency and Sovereignty Are Different Questions

  • Data residency is about location: The physical region where your data is stored and processed.
  • Data sovereignty is about jurisdiction: Whose legal system ultimately governs that data and who can compel its disclosure.

Under legislation such as the US CLOUD Act, a provider within US jurisdiction can be compelled to produce data even when it is held outside the United States. This means data sitting in a European data center can still be subject to foreign jurisdiction if it's held by a non-EU provider. A wholly European-owned provider with no non-EU parent closes off that potential exposure.

EU Sovereignty in Ardoq: Live Today

Customers who need it can now run their Ardoq environment in an EU data center operated by OVHcloud, with primary hosting in France. They get access to the same enterprise-grade platform, on infrastructure designed to keep it within European jurisdiction.

  • The Ardoq platform, tested end-to-end in the region.
  • Data stored and backed up within the European Union
  • Available now for proofs of concept as well as production.

 

"Keeping data in Europe isn’t enough if the servers storing it are owned overseas. We built this region for European organizations that need complete control over where their core data lives: EU-owned infrastructure, local backups, and strict legal independence for their data at rest."

Øystein Ellingbø, CTO

 

What We Commit To

Sovereignty is only as strong as what a provider does when tested. Where legally permitted, we will:

  • Notify you of any government or law enforcement request for your data.
  • Redirect requests to you as the data owner in the first instance.
  • Challenge requests that are unlawful, overbroad, or improperly served.
  • Disclose only what we are legally compelled to disclose, and never grant standing or backdoor access.

How This Compares With Other Enterprise Architecture Tools

Not every enterprise architecture platform answers the sovereignty question the same way. Some run on proprietary clouds: independent of the major non-EU hyperscalers, but closed and controlled by a single vendor. Others run on US-owned hyperscalers, which can offer European residency but leave the jurisdiction question open.

Ardoq now gives you the choice: EU residency on AWS and Azure, or, for customers who need it, an EU-owned sovereign cloud located and governed in Europe. For organizations where jurisdiction is a hard requirement, that difference decides which tools are even viable.
