Sovereign by design.
Trusted by Europe.
EUDISO connects European technology companies, researchers and public institutions to build open, privacy-first and EU-hosted digital infrastructure — without vendor lock-in and without compromise.
Europe needs digital infrastructure it can trust — built in Europe, for Europe.
EUDISO is an independent, non-profit initiative. We align technology companies, research institutions and public bodies around a shared commitment: sovereign by design — open by default.
- Anchor digital sovereignty as a competitive advantage for European industry.
- Reduce dependency on non-European hyperscalers through open, interoperable stacks.
- Make privacy, security and resilience the default — not an afterthought.
- Bridge the gap between public institutions, research and industry.
What we stand for
The foundations that every EUDISO member organization commits to.

Infrastructure

Collaboration

A common commitment — four non-negotiables.
