Data sovereignty used to be an abstract debate for tech CEOs. In 2026, after three rounds of EU rulings on US transfers and one major fine that hit a French SME, it is something every local business owner should understand in plain terms.

What changed since 2024

  • Schrems II ruling enforcement is now systematic: DPAs are auditing transfers, not just complaints.
  • The Data Act and AI Act add concrete obligations on where data lives and how it's used.
  • Customer awareness is real: 47% of EU consumers say they prefer brands using EU-hosted services.
  • Cyber insurance increasingly requires EU-only data residency for full coverage.

The questions to ask every supplier

  1. Where exactly are my customer's emails / phone numbers / behaviours stored?
  2. Are any sub-processors based outside the EU? Which ones, for which purposes?
  3. In case of a US legal request, what happens to my data?
  4. If you go bankrupt, how do I get my data back, in what format, in what timeframe?
  5. Do you have a current TIA (Transfer Impact Assessment) document?

Why this is a competitive advantage

Telling customers your platform, your hosting and your AI are 100% European is now a genuine selling point: especially for businesses targeting professionals, public sector, or environmentally aware consumers. It is also a great answer when a customer asks "what happens to my data?"

"When we tell customers our platform is fully European, hosted in France, and never sends their data to the US: half of them say "thank you, we've been waiting for this"."
