For us, data sovereignty is engineering practice, not a buzzword. We advise on Schrems II, GDPR, BSI C5 and ISO 27001 and translate legal requirements into concrete architectures in which your personal data demonstrably stays inside your jurisdiction.
To achieve that we combine open-source building blocks only — Kubernetes, Proxmox, OpenStack, Nextcloud, Keycloak, Authentik, MinIO — with European hosting options or your own data center. Every component is open, auditable and free of hidden data flows.
Our approach is deeply tailored to your organisation: we start with a sovereignty assessment, identify US cloud dependencies, critical data flows and processing contracts, derive a prioritised roadmap and accompany the rebuild all the way into production. You retain full control over data, processes and source code — with clear handovers and complete documentation.
