What is Chainguard?

Thu, 23 Jul 2026 00:00:00 +0000

Nearly every modern application is built on open source software. That software is powerful, but it arrives with problems: vulnerabilities (including publicly disclosed CVEs), unpatched dependencies, unclear provenance, and the constant work of keeping it all up to date. Tracking and fixing these issues across a large codebase consumes engineering time that could go toward building products.

Chainguard’s mission is to be the secure source for open source. Rather than leaving you to patch and harden open source software yourself, Chainguard rebuilds it from source in a hardened build environment, keeps it continuously updated, and distributes it with the metadata you need to verify what you’re running. The result is software that carries low-to-no known CVEs and requires far less remediation work from your team.
