Chainguard vs RapidFort Hardened Images

Chainguard's contractual SLA guarantees critical CVEs within 7 days and high, medium, and low severity within 14 days. Chainguard's actual remediation times are significantly faster — here are Chainguard's average remediation times, broken down by CVE severity (based on The State of Trusted Open Source: December 2025):

• Critical CVEs: Under 20 hours average (63.5% within 24 hours, 97.6% within two days, 100% within three days)

• High CVEs: 2.05 days average

• Medium CVEs: 2.5 days average

• Low CVEs: 3.05 days average

RapidFort claims similar patch targets, but it has no publicly available, contractual SLA and relies on upstream distros for patches, meaning its remediation timelines depend on when Debian, Ubuntu, or Red Hat issue fixes, which is a dependency that Chainguard avoids.

Chainguard's third-party application images and Helm charts are drop-in replacements; base images require a one-time Dockerfile refactor. Your existing CI/CD process, testing, and deployment workflow are fully preserved. RapidFort's debloating approach requires reworking your CI/CD pipeline to add debloating and retesting steps, plus an ongoing investment in automated test suites with comprehensive coverage to ensure debloating doesn't break application functionality.

Debloating is the process of analyzing a running container to identify unused packages and files, then stripping them out. While this reduces image size and attack surface, it can leave behind "unowned" files. These are orphaned artifacts with no package metadata, which erode SBOM accuracy and can cause scanners to miss vulnerabilities or flag false results. Chainguard avoids this entirely by building minimal images from source that include only the dependencies required to run your application, preserving full package metadata and SBOM integrity.

Yes. Chainguard's Custom Assembly lets you add packages, certificates, and environment variables to any image from a catalog of 30,000+ packages. Custom-assembled images remain under Chainguard's CVE remediation SLA (when using packages from entitled images).

Chainguard holds its own CMVP-validated certificates for the Chainguard FIPS Provider for OpenSSL 3.4, with a kernel-independent implementation that runs in FIPS mode on any host OS. RapidFort offers FIPS 140-3 compliance through third-party validated modules embedded within legacy distros, which may limit deployment flexibility compared to Chainguard's kernel-independent approach.

Chainguard Libraries provides malware-resistant rebuilds of Python, Java, and JavaScript libraries built from source with signed SBOMs and SLSA Level 3 provenance, plugging directly into PyPI, npm, and Maven with zero workflow changes. Chainguard also offers VM images, Helm charts, OS Packages, Chainguard Actions (hardened CI/CD workflows), and Agent Skills for AI workflows. RapidFort does not currently offer language library security, CI/CD hardening, or AI agent security.
