Chainguard

Minimal, continuously rebuilt container images and libraries shipped with few or no known CVEs.

Chainguard produces hardened container base images, virtual machine images, and language ecosystem libraries that are rebuilt from source and delivered with signatures and SBOMs. Engineering teams use them to shrink vulnerability backlogs and meet compliance requirements without patching upstream images themselves. The company was founded in 2021 by former Google open source security engineers.
