CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
Teams currently locked into tfsec for Infrastructure-as-Code scanning should migrate to Trivy because it adds container image and filesystem vulnerability detection without forcing a new workflow. Trivy handles Terraform misconfigurations at feature parity with tfsec while covering the gaps tfsec deliberately ignored, giving you a single tool that doesn't require separate SAST or container scanning solutions. Skip this if you've already standardized on a commercial CSPM like Prisma or CloudSploit; Trivy's strength is breadth over depth on any single workload type.
