Prowler vs ScoutSuite vs cloud-audit [2026]

As of 2026, we can find many open source tools that scan AWS accounts for potentially unsafe configurations. Anyone who cares about the security of their AWS infrastructure has likely already searched for such tools and stumbled upon Prowler, ScoutSuite, Trivy, Steampipe, and a few others while browsing "best tools" rankings.

I've used most of them myself. I've seen both pros and cons. This prompted me to dedicate the time to creating my own scanner. In this post, I'd like to compare three CLI-based scanners - Prowler, ScoutSuite, and Cloud-Audit (my tool). I'll try to be as objective as possible, but I'll let the comparison speak for itself.

Each solves different problems at different scales. I'll point out where each scanner fits and where it doesn't.
