CST VerdictBased on our analysis of available product data, here is our conclusion:
Teams building compliance automation on AWS will extract the most value from AWS Config Rules Repository because it's free and community-maintained, meaning no vendor lock-in and rules that evolve with real deployment patterns rather than marketing cycles. The repository has 1,714 GitHub stars and covers the Config Rules API surface broadly enough that most teams won't need to write rules from scratch. Skip this if you need a managed compliance platform with remediation workflows and audit trails; this is a rules library for teams who already own their Config infrastructure and want to avoid vendor SaaS pricing.
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.
