CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
I-ISMS (Industrial Information Security Management System)
Industrial security teams building an ISMS from scratch will appreciate I-ISMS because it's free Word templates that actually map to IEC 62443 and ISO 27001 requirements instead of forcing you to hire a consultant or start blank. The 116 GitHub stars signal real adoption among OT practitioners who've validated the policy language against actual audits. Skip this if your organization already has a mature documentation baseline or needs automated compliance monitoring and continuous control testing; I-ISMS is a documentation framework, not a control execution platform.
