True control over your business data — legally resilient, self-determined, and independent of monopolies.

Hyperscalers like Microsoft, AWS, and Google offer immense convenience, but frequently trap organizations in proprietary ecosystems (vendor lock-in). Concurrently, legal frameworks such as the US CLOUD Act create persistent compliance and secrecy risks when handling sensitive corporate and European customer data.

Data sovereignty does not mean abandoning modern cloud technology — it means making deliberate architectural choices that ensure full ownership over your data, encryption keys, and migration paths.


Key Risk Areas & Capabilities

Data Sovereignty & Cloud Independence

  • Jurisdiction & location security (EU hosting & hybrid cloud): Run mission-critical workloads on European cloud platforms (e.g., Hetzner, OVH, Open Telekom Cloud) or hardened on-premise systems — completely shielded from US CLOUD Act access orders.
  • Self-managed encryption keys (BYOK / HYOK): Implement client-side and end-to-end encryption where keys are held exclusively by your organization. Even if data resides in a public cloud, the provider cannot decrypt it.
  • Exit strategies & lock-in liberation: Architect portable solutions leveraging open standards, containerization (Docker/Kubernetes), and open APIs. Migrate workloads between providers without crippling friction.
  • Protection of intellectual property & trade secrets: Ensure proprietary engineering designs, confidential source code, and client records are not jeopardized by ambiguous cloud terms of service.
  • GDPR resilience & audit readiness: Meet stringent data protection covenants required by enterprise clients, auditors, and cyber insurers.

How We Work Together

  • Hourly & independent: As an independent security architect, I do not resell licenses or hoster contracts. My advice is 100% vendor-neutral.
  • Pragmatic, not dogmatic: Strike the right balance: standard public cloud where economically sensible — uncompromising sovereignty where your core business secrets reside.
  • On-site or remote: On-site across the Rhine-Neckar metropolitan region (Mannheim, Heidelberg, Karlsruhe) or remotely nationwide.
