I built a Terraform security scanner that lives inside GitHub PRs

Short summary

TerraWatch is a GitHub App scanning Terraform PRs for security issues—public S3 buckets, IAM wildcards, open ports—with inline fix suggestions. Lightweight, no YAML config needed, all changes reviewed before merge; free beta available starting today.

  • Catches infrastructure-as-code security misconfigurations in pull requests automatically
  • Requires 2-minute GitHub App install with no CI config or webhook setup needed
  • 29 security rules with hardcoded diffs developers review before merge; free beta launching today

Generated with AI, which can make mistakes.

Is this a good recommendation for you?
