Why not the clouds?

Digital sovereignty is not a marketing argument. It's a real constraint that your cloud providers don't solve.

Your data stays within your walls

No transit to data centers subject to the Cloud Act, FISA, or equivalents. Your secrets remain your secrets.

NIS2, DORA, GDPR compliant

Our solutions are designed for European regulatory constraints, not retrofitted after the fact.

Auditable and open source

Every critical component is open source. You can audit, fork, and deploy without our permission.

Operational, not theoretical

We deploy in air-gap environments ourselves. This isn't a slide deck — it's field work.

Expert support.

A field expert who has deployed in defense environments, not a salesperson.

Audit & Architecture

Assessment of your AI security posture, sovereign architecture recommendations, remediation plan.

Deployment & Integration

Production deployment of your secure AI solutions: on-prem, air-gap, TEE. PKI integration and secrets management.

Training & Knowledge Transfer

Cybersecurity awareness, sovereign tools training, skills transfer to your teams.
