CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams investigating suspected AWS credential compromise or insider threats will find AWS Key Usage Detector invaluable for pinpointing when and where stolen keys were actually used across your infrastructure. The tool's free pricing and direct CloudTrail analysis mean you can run forensics immediately without vendor lock-in or waiting for procurement; the 122 GitHub stars signal active use by practitioners, not theoretical adoption. This is a forensic instrument, not a prevention layer, so skip it if you need real-time detection of compromised credentials before they're exploited, or continuous monitoring across accounts without manual CloudTrail export workflows.
AWS incident responders investigating active compromises across multiple EC2 instances should know about Diffy; it surfaces behavioral anomalies and file differences that manual comparison misses, collapsing hours of forensic work into minutes. Netflix open-sourced the tool with 631 GitHub stars and zero licensing friction, meaning you can deploy it immediately without vendor negotiations. Stop here if your incidents span on-premises systems or non-AWS cloud providers, since Diffy was purpose-built for AWS instance forensics and lacks the portability you'd need.
