kube-bench is a free container security tool. RapidFort Runtime Protection is a commercial container security tool by RapidFort. Compare features, ratings, integrations, and community reviews side by side to find the best container security fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Enterprise security teams managing large Kubernetes clusters will see the fastest ROI from RapidFort Runtime Protection because it cuts container attack surface by up to 90 percent while adding less than 1 percent compute overhead, eliminating the usual performance tradeoff that kills adoption. The platform's execution path analysis directly addresses NIST ID.RA by surfacing only reachable vulnerabilities instead of flooding teams with noise from unreachable flaws. Skip this if you need multi-cloud coverage or runtime protection outside Kubernetes; RapidFort is built specifically for hardening containerized workloads, not general infrastructure.
Kube-bench is a security assessment tool that validates Kubernetes deployments against CIS Kubernetes Benchmark standards through automated configuration checks.
