GDPR-Compliant Collaboration — replace Microsoft 365 sovereignly
Self-hosted alternative to Microsoft 365 and Google Workspace: files (Nextcloud Files), calendar, contacts, mail, office (Collabora Online / OnlyOffice), chat (Talk) and video conferencing — fully under your own data sovereignty, on-premise or in sovereign EU cloud.
Schrems II-safe: no data transfer to the US, fully GDPR-compliant, BSI Grundschutz-ready, and approved for critical infrastructure, public sector and healthcare.
We deliver: architecture (high availability, object storage, full-text search), migration from Microsoft 365/Google Workspace including mail, file and calendar takeover, single sign-on via Keycloak, end-to-end encryption, backup and 24/7 support.
