CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Enterprise and mid-market security teams managing multi-vendor firewall estates will find FireMon Policy Workbench essential for reducing policy sprawl before it becomes a compliance liability. The platform validates policies against PCI DSS, NIST, and DORA frameworks during design rather than after deployment, which means fewer audit findings and faster change cycles; combined with ITSM integration, this addresses the GV.PO and PR.PS gaps most organizations ignore until a breach forces remediation. Skip this if your firewall estate is small or standardized on a single vendor's management suite; the value scales with complexity.
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.
