Chainguard provides hardened, minimal container images that are continuously rebuilt from source in secure environments, aiming to eliminate known vulnerabilities and ensure end-to-end integrity. These images come with built-in cryptographic signatures, Software Bill of Materials (SBOMs), and Supply-chain Levels for Software Artifacts (SLSA) provenance. In addition to container images, Chainguard offers a catalog of guarded Java dependencies through its Chainguard Libraries, built securely from source in SLSA-certified infrastructure. The company also contributes to and maintains several widely used open source projects, reflecting its commitment to the open source community.
