Why Cyberus
Software built to last decades.
When SAP chose our hypervisor, and when the BSI selected it for VS-NfD accreditation, neither of them read a brochure. They examined the code, reviewed the methodology, and evaluated the team. What they found was a way of building software that makes verification possible: not a promise, but a proof. That is what sets Cyberus’ code apart:
Built to be verified
What gets evaluated is exactly what gets deployed.
- Declarative builds with Nix: every dependency is explicitly defined, nothing is implicit
- Cryptographically pinned binaries: bit-identical across every system and every point in time
- Fully open-source and auditable: no black boxes, no trust required
Engineered without compromise
Security is a structural property, not a layer added on top.
- Built on Linux and KVM: battle-tested foundations with over two decades of global deployment
- Written in Rust: entire classes of memory safety vulnerabilities ruled out at compiler level
- No proprietary lock-in: the code remains accessible and auditable regardless of us as a vendor
Tested like it matters
No quality debt. What ships today won't be a liability tomorrow.
- Shift-left methodology (Cidoka): testing starts at the first line of code, not before release
- Continuous, automated testing on real hardware — not simulated environments
- CI/CD pipelines that catch issues early, so speed and confidence are not in conflict
Supported for the long run
Infrastructure built today remains maintainable in decades.
- Long-term support for NixOS platform: predictable update cycles, no forced migrations
- Development and support based in Germany
- Open-source foundation: no dependency on our roadmap
