CST VerdictBased on our analysis of available product data, here is our conclusion:
Teams managing AWS infrastructure who need to catch credential leaks before they become incidents will find Dufflebag's focus on public EBS snapshots invaluable; it hunts a blind spot most scanners skip entirely. The free pricing and 299 GitHub stars signal active community validation of the detection logic. This is not for organizations needing a managed service with incident response integration or compliance reporting; Dufflebag is a scrappy, self-operated tool that rewards teams willing to run it themselves and act on findings quickly.
DevOps teams and security engineers doing periodic S3 audits will find real value in S3Scanner's speed and specificity; it catches bucket policy misconfigurations and public access vectors that generic CSPM tools often miss in their first scan. The 3,022 GitHub stars reflect active maintenance and community trust from practitioners running it in production environments. Skip this if you need continuous monitoring and automated remediation across hundreds of buckets; S3Scanner is built for manual scans and one-off assessments, not real-time drift detection.
