CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams operating Kubernetes environments need Anchore Enforce for its policy-as-code enforcement model, which closes the gap between vulnerability scanning and actual compliance gates in the pipeline. Pre-built policy packs for FedRAMP, NIST, and DISA compliance plus runtime monitoring of live clusters means you're covering both ID.AM (asset inventory) and DE.CM (continuous monitoring) without bolting on separate tools. Skip this if your organization lacks the infrastructure-as-code discipline to maintain JSON policies or if you need vulnerability remediation guidance; Anchore Enforce is strict enforcement, not hand-holding.
Platform engineers enforcing Kubernetes security policies at scale should choose Gatekeeper Library for its parameterized policy templates and native CRD integration, which let you define and extend controls without rebuilding from scratch. The 4,168 GitHub stars signal real adoption among teams actually running this in production, not just evaluating it. This is free, so cost isn't a barrier, but skip it if your security team needs policy management divorced from Kubernetes,Gatekeeper is admission control for K8s clusters, not a centralized policy engine for your entire infrastructure.
