CST VerdictBased on our analysis of available product data, here is our conclusion:
AWS teams with S3 buckets exposed to multiple permission models will benefit most from S3cario's scenario-based testing, which catches permission misconfigurations that static policy reviewers overlook. The tool is free and requires no agent deployment, making it practical for teams running quick permission audits across dozens of buckets. Skip this if you need continuous compliance monitoring or CIEM-style access analytics; S3cario is a one-time assessment tool, not a runtime guardian.
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.
