Clair vs RapidFort

Clair is a free, Apache 2.0-licensed open-source service for static vulnerability analysis of OCI and Docker container images. It runs self-hosted on Linux and exposes an API: clients submit image manifests, Clair indexes their layers, scans image contents, and returns a persisted IndexReport. Analysis examines image contents rather than runtime behavior. Content-addressed OCI manifests and layers help avoid duplicate indexing. Clair continually ingests security data, while matcher requests provide current vulnerability analysis for an IndexReport; its notifier checks indexed manifests when new vulnerabilities appear and follows configured actions. The documented support matrix includes Ubuntu, Debian, RHEL, SUSE, Oracle, Alpine, AWS Linux, VMware Photon, and Python base containers. Clair v4 uses ClairCore as its analysis engine. Release 4.9.0 notes NVD 2.0 JSON feeds for CVSS enrichment and SPDX 2.3 encoding for index reports. The README lists a mailing list, IRC channel, and GitHub issues for community contact, and directs users to releases because the main branch may be unstable or broken. The listed plan is free.

RapidFort is a software supply chain security platform for containerized applications, combining vulnerability analysis, runtime visibility, image hardening and compliance validation. Its Analyzer scans images, registries, CI pipelines and clusters, with validated vulnerability intelligence intended to reduce scanner noise. Profiler reports runtime behavior and creates a Runtime Bill of Materials from production usage; Optimizer removes unused components and refreshes hardened images on continuous 24-hour cycles. RapidFort also offers more than 35,000 curated near-zero-CVE container images. Its CART service provides ongoing compliance validation and audit artifacts aligned with benchmarks including CIS, STIG, NIST, HIPAA, PCI and FedRAMP. The free plan costs nothing and includes five curated images from a limited catalog, daily rebuilds and patching, and standard container registry compatibility. Full-catalog and platform plans have no listed price. RapidFort describes on-premises deployment, including air-gapped environments, and says continuous runtime profiling has less than 1% overhead without application changes. It presents the platform for security, DevSecOps and procurement teams, including those in regulated or mission-critical environments.
