CST VerdictBased on our analysis of available product data, here is our conclusion:
Platform engineers and security teams managing IAM sprawl across multiple AWS accounts will get immediate value from aws-lint-iam-policies because it catches overpermissioned policies at commit time, before they propagate across your organization. The tool runs on Access Analyzer validation rules, the same engine AWS uses internally, so findings carry real weight without requiring a separate security approval layer. Skip this if you need a point-and-click CSPM dashboard or drift detection across running resources; this is CLI-first and best suited to teams already embedding security checks into infrastructure-as-code pipelines.
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.
