CST VerdictBased on our analysis of available product data, here is our conclusion:
AWS teams that need immutable audit logs for compliance and incident response should start with CloudTrail; it's free, ships with AWS, and captures every API call across your account, making it the baseline that most security programs build on. The service is SOC 2 Type II certified and satisfies most regulatory audit requirements without additional tooling. Skip CloudTrail if you're looking for behavioral threat detection or real-time alerting on suspicious activity; it's a log collection engine, not an analytics platform, so you'll need a SIEM or security data lake downstream to actually find the signal in the noise.
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.
