CST VerdictShort answer
DevOps and platform engineering teams already paying for Datadog's observability platform should adopt Datadog IaC Security to catch misconfigurations before they reach production; the pre-deployment scanning integrates directly into your CI/CD pipeline without another vendor relationship. Its coverage of PR.PS and ID.RA functions means you're addressing both infrastructure hardening and risk visibility at code time, which is where the remediation cost is lowest. Skip this if your organization uses Terraform or CloudFormation primarily as deployment artifacts after manual approval workflows; the tool's value hinges on shifting left into active development cycles. 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.
