Chainguard vs RapidFort Hardened Images
Modernize your software supply chain with trusted open source artifacts built from source, not debloated after.
Features
Catalog Depth
2,000+ projects (7,000+ version tags),, 700+ FIPS images, and broad Helm Chart support
~187 repos (they market “15k+ images”, but that is just counting version tags, not distinct base projects/images)
Security SLA
Contractual 7/14 Day SLA, with actual average patch times significantly faster: Critical <20 hours, High 2.05 days, Medium 2.5 days, Low 3.05 days
No publicly referenceable SLA (they’re gated by the upstream distros they debloat)
Supply Chain
Purpose-built OS. Total control from source to artifact
Reliant on debloated legacy distros (Debian/Alpine),
Compliance
Delivers the Chainguard FIPS Module for OpenSSL 3.4 (CMVP-validated), a Chainguard-developed module enabling in-container, kernel-independent FIPS enforcement.
Reliant on third party FIPS module with unclear rebranding status, raising audit concerns
Customization
Automated Custom Assembly with 15k+ packages, all covered under Chainguard’s CVE SLA
No customization tooling
Expansion
Language Library support across Python, Java, and JavaScript.
No additional open source artifacts
The world’s leading companies trust Chainguard

Talk to an expertBuilt secure by design vs. post-hoc “debloating”
Chainguard builds minimal, hardened images from source rather than stripping down existing images, eliminating hidden binaries and audit blind spots, and enabling industry-leading remediation times.
Wall-to-wall coverage for every dev
A catalog of over 2,000 projects (including 700+ FIPS), spanning from container images to Helm Charts to language libraries – trusted OSS artifacts for everyone in your organization.
Purpose-built OS for seamless adoption
Chainguard integrates into existing workflows and pipelines, rather than requiring added build steps and ongoing migration work.
