Chainguard

Chainguard Containers is a catalog of 1,700+ minimal, distroless container images that eliminate software supply chain vulnerabilities through continuous source rebuilds and zero-CVE architecture. Unlike traditional container registries that aggregate community images, Chainguard builds every image from source using its proprietary Chainguard OS (based on Wolfi undistro), achieving an average 97.6% reduction in Common Vulnerabilities and Exposures (CVEs) compared to standard open source equivalents while maintaining production-ready performance.

The platform rebuilds all container images nightly from verified source code with industry-leading remediation Service Level Agreements (SLAs): 7 days for critical CVEs, 14 days for high/medium/low severity vulnerabilities. Each image is cryptographically signed with Sigstore, includes high-quality Software Bills of Materials (SBOMs), and maintains Supply Chain Levels for Software Artifacts (SLSA) Level 2 compliance, with automated Chainguard Factory managing the entire build, test, patch, and release pipeline on Kubernetes infrastructure.

Founded in 2021 by former Google and VMware engineers and headquartered in Kirkland, Washington, Chainguard has raised $612M in total funding with a $3.5B valuation as of April 2025 and serves over 150 enterprise customers. The company holds SOC 2 Type II certification and supports compliance frameworks including FedRAMP, PCI DSS, ISO 27001, and NIST 800-171, with integrations spanning leading vulnerability scanners and artifact management platforms.
