AN OPEN-SOURCE LINUX-BASED HYPERVISOR

Sovereignty You Can Audit

A verifiable virtualization layer for cloud providers building sovereign infrastructure. Open source, reproducible, and authorized for BSI VS-NfD classified workloads.

OUR SOLUTION

Verifiable by Design

Every cloud offering advertises with “sovereign”, but what actually means it? If you ask how sovereignty is actually implemented at the virtualization layer, most providers point to organizational measures: contracts, jurisdictions, perimeter controls. The Cyberus Hypervisor and CTRL-OS give cloud providers a virtualization foundation whose security claims can be independently checked:

  • 100% Open Source

    No black boxes at the isolation boundary and every line of code in the stack is inspectable.

  • Reproducible Builds

    Anyone can rebuild the exact binaries from source and verify that what runs in production matches the published code.

  • BSI-Authorized Isolation

    The approval process required an in-depth technical evaluation of the isolation properties, conducted by the authority itself.

We run what we sell

Every release of our hypervisor and CTRL-OS is tested automatically on physical hardware using Cidoka, our own test platform, before it ships. The same discipline we apply to ourselves, we offer to our customers.

  • Every release tested on physical hardware
  • Same discipline, internally and externally
  • Documented test evidence for your auditors
