Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Platform engineering teams managing multi-cloud infrastructure at scale will get the most from Cloud Custodian because its YAML-based policy engine lets you write once and enforce across AWS, Azure, and GCP simultaneously, something most CSPM tools force you to configure separately. 5,794 GitHub stars and active community contributions mean you're inheriting battle-tested policies rather than starting from scratch. Not the right fit if you need point-and-click policy management or expect vendor support; Cloud Custodian demands engineering resources to deploy and maintain, and you're responsible for the policy logic.
Plexicus Cloud Security Posture Management
Mid-market and enterprise teams managing multi-cloud infrastructure across AWS, Azure, GCP, and OCI will see the fastest payoff from Plexicus Cloud Security Posture Management because its one-click remediation and CI/CD integration actually close gaps instead of just flagging them. The platform maps to SOC 2, ISO 27001, PCI DSS, and NIST frameworks out of the box, cutting weeks off compliance preparation. Skip this if you need deep identity and access governance; Plexicus prioritizes misconfiguration detection and remediation over the fine-grained CIEM capabilities that larger enterprises often layer on top.
