Long-Term Support for Your Package Set

Are you evaluating Nix or NixOS for your product? Are you worried about CRA obligations for manufacturers? Does NixOS' fast upgrade cycle keep you up at night?

Cyberus Linux addresses all of these concerns. We offer commercial support with SLAs tailored to your package set. We are a manufacturer in terms of the CRA, taking over CVE monitoring obligations and providing assistance with compliance documentation. Cyberus Linux 26.05 will provide stable long-term support until May 2031.

Three steps to a CRA compliance plan for your product:

  1. Get started now with the freely available packages.
  2. Generate your first SBOM.
  3. Schedule a free consultation on SBOM size and CRA requirements.
