CST VerdictShort answer
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. Mid-market and enterprise teams managing multi-cloud infrastructure across AWS, Azure, and GCP should pick Fluid Attacks CSPM for its reattack verification capability, which actually validates that fixes work instead of just flagging misconfigurations. The AI-assisted remediation with custom fix options and pentester support addresses the gap most teams face in ID.RA Risk Assessment, turning vulnerability discovery into closure. Skip this if your organization needs a single platform covering code scanning, container security, and cloud posture in one pane; Fluid Attacks is deliberately cloud-posture focused.
