Why RapidFort over Chainguard?
The Advantages of open source over Proprietary Chainguard OS.
Innovation Velocity
Millions of developers continuously improve every LTS distribution RapidFort is built on. No single company's roadmap can match that velocity.
Security by Scrutiny
Open source is continuously tested by security researchers worldwide. Chainguard OS has minimal external scrutiny by comparison. Vulnerabilities go undetected.
Compatibility That Holds
Chainguard OS creates compatibility risk with every module you add. Open source keeps everything your team already knows working exactly as expected.
Head to Head
RapidFort vs Chainguard.
Capability
RapidFort
Chainguard
OS
Foundation and ecosystem
Open Source LTS
Genuine open source support for Ubuntu, Red Hat UBI, Debian, Alpine, Oracle Linux, and Amazon Linux. You can always go back to the source.
Only Supports Chainguard OS
Source code is a single-source, proprietary, non-open, non-standard distribution, with no community support.
Migration Effort
Time to adopt
Drop-In
No changes to your package manager, pipelines, or build scripts. Support for every package and library.
Requires Full Migration
Requires migrating to Chainguard OS across every image in your stack and lacks support for all libraries and packages. No seamless path back to open source.
DISA STIG
Federal accreditation
Accredited
RHEL, Oracle Linux, and Ubuntu STIGs apply directly.
Not DISA Supported
Chainguard is not supported by DISA. OpenSCAP GPOS SRG profile only, which is not equivalent to STIG accreditation.
Platform Scope
Beyond base images
End-to-End
Integrated scanner, STIG/CIS benchmarking, runtime profiling, and hardening in one platform.
Images Only
Dependent on third-party scanners. No integrated benchmarking or STIG support.
Patched vs Daily Build
Release approach
Patched
RF images are patched with minimal code changes and robust software change management.
Daily Build
Chainguard builds latest software and ships to customers, without vetting and scrutiny of the well established distributions.
