CST VerdictBased on our analysis of available product data, here is our conclusion:
Development teams shipping containers through CI/CD pipelines should start with Clair because it catches known vulnerabilities at build time before they reach production, and the free, open source model means zero licensing friction for catching this at scale. With 10,942 GitHub stars and deep integration into container registries via API indexing, Clair is battle-tested in high-volume scanning workflows. Skip it if you need runtime threat detection or vulnerability prioritization based on exploitability; Clair is static analysis only, which means it flags everything in the database regardless of whether the vulnerability actually matters for your application.
Teams running Kubernetes who need to know whether their cluster configuration actually matches CIS Benchmark standards should start with kube-bench; it's free, it runs locally, and it will catch misconfigurations that most teams have never audited. The tool covers 93 checks across control plane, node, and policies, which means you'll find real gaps in RBAC, network policies, and pod security posture in your first run. Skip this if you need continuous runtime monitoring or remediation automation; kube-bench is a point-in-time scanner that tells you what's broken, not what's attacking you.
