Prowler
Top pickOpen-source cloud security posture scanning with framework check packs.
92
sovereigntyScans AWS, Azure, GCP and Kubernetes against hundreds of checks and maps them to compliance frameworks including CIS, SOC 2, HIPAA, GDPR and NIST. Runs as a CLI in CI or as a self-hosted app, and produces the technical-control evidence a compliance platform would otherwise gather for you.

What it does well
- +Framework mappings are built in — SOC 2, CIS, HIPAA, GDPR, NIST and more, not just raw findings
- +Runs in CI, so posture is checked on every change rather than the week before an audit
- +Covers the part of compliance that is genuinely automatable: technical control state
Where it falls short
- −Produces evidence, not an audit — no auditor relationship, no report
- −No policy management, security training tracking or vendor review workflow
- −Someone has to own the findings; the tool will not chase them
