Secure infrastructure for KRITIS

Increasing regulatory requirements, growing security risks, and rising operational complexity are presenting new challenges for critical infrastructure and energy companies. What is needed is an infrastructure that is not only high-performing but also enables control, traceability, and long-term autonomy. This is exactly where our platform comes in.

Sovereignty guaranteed

Full control over data, infrastructure, and operations—on your own hardware. No reliance on hyperscalers or external cloud providers.

Unmatched performance

Designed to meet NIS2, BSI Basic Protection, and KRITIS requirements. Standardized architecture simplifies audits and compliance verification.

Automated operation

Standardized and automated processes reduce manual effort, minimize errors, and improve operational reliability.

Transparency & auditability

Transparent processes and clear structures lay the groundwork for successful audits and full control.

Technology without lock-in

An open-source-based platform for maximum flexibility—without relying on any single vendor.

Optimized for KRITIS

Designed for highly critical environments with the most demanding requirements for security, availability, and stability.
