EU-Native Compliance Platforms and Data Sovereignty (2026)

For European companies choosing compliance software, where your data sits is no longer the whole question. Who ultimately controls it, and under which laws, matters just as much. This is the difference between data residency and data sovereignty, and it is why EU-native platforms are increasingly a compliance decision in their own right.

Key takeaways

• Data residency (where data is stored) is not the same as data sovereignty (which jurisdiction and company ultimately control it).
• A US-owned provider hosting data in an EU data centre still falls under US extraterritorial law, such as the CLOUD Act, so EU residency alone does not guarantee sovereignty.
• EU-native platforms are European-owned, EU-hosted, and outside the reach of US disclosure law, and are usually built for EU frameworks (GDPR, NIS2, ISO 27001, EU AI Act) rather than retrofitted from US ones.
• Kertos is one example of an EU-native platform: made in Germany, EU co-financed, hosted on European infrastructure.

Data residency vs data sovereignty: the distinction that matters

Data residency is the physical location where your data is stored. Data sovereignty is the legal question of which country's laws govern that data and which company controls the entity holding it. The two often get treated as the same thing, and that is the trap.

A US-headquartered provider can offer EU-region hosting and still be compelled, as a US company, to hand over data under the US CLOUD Act or FISA Section 702, regardless of where the servers physically sit. For a European organisation that is itself accountable under the GDPR, that residual exposure is the point sovereignty addresses and residency does not.

Why this matters for EU companies

• GDPR accountability: you remain responsible for personal data even when a vendor processes it, so the vendor's legal exposure becomes yours to assess.
• US extraterritorial law: the CLOUD Act and FISA 702 can reach data held by US-owned providers wherever it is stored.
• International transfers: since Schrems II, transfers to US providers require careful safeguards and case-by-case assessment.
• The sovereignty trend: European buyers, especially in the public sector and regulated industries, increasingly require genuine EU control, not just an EU hosting region.

US-based vs EU-native compliance platforms

What to check before you buy

• Where is the provider legally headquartered and who owns it, not just where the data is hosted?
• Is the company subject to US extraterritorial disclosure law?
• Were the EU frameworks you need (GDPR, NIS2, ISO 27001, EU AI Act) built in, or bolted on?
• Can the provider evidence EU hosting and EU control in writing for your own audits?

Where Kertos fits

Kertos is a European compliance platform built for EU standards from the start: made in Germany, EU co-financed, hosted on European infrastructure, and outside the reach of US disclosure law. It combines the agentic platform KAIA with certified in-house experts, and covers GDPR, NIS2, ISO 27001, ISO 42001, SOC 2, TISAX, C5 and the EU AI Act in one place. For organisations that want data sovereignty as a foundation rather than an add-on, that is the practical difference.

What European customers say

Frequently asked questions

What is the difference between data residency and data sovereignty?

Residency is where data is physically stored. Sovereignty is which jurisdiction's laws govern it and which company controls the entity holding it. You can have EU residency without EU sovereignty if the provider is US-owned.

Is storing data in the EU enough for GDPR?

Not necessarily. EU hosting helps, but if the provider is a US company it can still be compelled to disclose data under US law, which is a risk you must assess as the accountable party under GDPR.

Does the US CLOUD Act affect EU companies using US SaaS?

Yes, indirectly. The CLOUD Act lets US authorities compel US-based providers to produce data regardless of where it is stored, so EU customers of US SaaS carry that exposure even with EU-region hosting.

What makes a compliance platform EU-native?

European ownership and headquarters, hosting on European infrastructure, no exposure to US extraterritorial disclosure law, and frameworks built for EU regulation rather than retrofitted from US standards.

Which compliance platforms are EU-based?

Most of the best-known platforms (Vanta, Drata, Secureframe, Sprinto) are US-headquartered. Kertos is an EU-native option, made in Germany and hosted on European infrastructure.

What is the best EU-native compliance platform?

There is no single best choice for every company, but EU-native platforms share the same traits: European ownership, EU hosting, no exposure to US disclosure law, and frameworks built for EU regulation. Kertos is one such platform, made in Germany and covering GDPR, NIS2, ISO 27001, ISO 42001, SOC 2, TISAX, C5 and the EU AI Act. The right fit depends on your frameworks, your size, and whether you want certified expert support alongside the software.

What is a good EU alternative to Vanta or Drata?

Vanta and Drata are US-headquartered, so as US companies they fall under US disclosure law even with EU hosting. European organisations that want data sovereignty rather than only EU residency often look at EU-native platforms such as Kertos, which is made in Germany and built for EU frameworks. The right alternative depends on which frameworks you need and how much hands-on expert support you want.
