We architect the migration of European public and private sectors from proprietary US platforms to high-performance, sovereign alternatives. Secure, compliant, and under your absolute control.
Proprietary US tech is no longer just a vendor choice — it's a jurisdictional liability for European entities. Click any card to learn more.
US authorities can compel American providers to hand over data stored anywhere globally. European residency offers no legal protection under US jurisdiction.
Recent incidents have proven that US platforms can and will be weaponized for political leverage. Your core infrastructure should not be subject to foreign policy shifts.
Monopolistic ecosystems create technical debt that compounds daily. Breaking the cycle requires expert architectural intervention, not just new software.
We don't just point you at open source software. We manage the entire journey from your first discovery conversation to full deployment and ongoing support.
We map your entire US technology dependency — every Microsoft and Google touchpoint across your organisation. You receive a clear picture of your exposure and a prioritised migration roadmap.
We run your migration using a continuous sync model — not a risky lift-and-shift. Both environments run simultaneously. Teams move in cohorts. Zero downtime. No lost data. Full permission integrity preserved.
The technology is the easy part. We manage the human side — translating years of Microsoft muscle memory into sovereign stack workflows, with role-specific training for every level of your organisation.
Post-migration support contracts and strategic advisory for organisations building long-term digital sovereignty programmes. We stay with you as the stack evolves.
We replace every layer of the US productivity stack with enterprise-grade, European-owned alternatives.
Central identity and access management. Federates with existing Active Directory and Entra ID — your users keep their existing credentials during migration.
File sync, sharing, and content collaboration hosted in Europe. France's Ministry of Education has 400,000 employees on Nextcloud — targeting 1.2 million.
End-to-end encrypted messaging via the open Matrix protocol. Used by the French government (5.5M civil servants), German Bundeswehr, and the European Commission.
Full document, spreadsheet, and presentation editing. Native .docx and .xlsx compatibility. Nexus MSP is one of the UK's first official Office EU implementation partners.
We integrate these best-of-breed tools into a unified workplace experience — openDesk — the German government-backed sovereign workplace suite. Delivering the usability of M365 without the jurisdictional risk.
