CST VerdictBased on our analysis of available product data, here is our conclusion:
DevSecOps teams running GitHub Actions at scale need Gato because it's the only tool that systematically maps and exploits CI/CD pipeline misconfigurations before attackers do. With 701 GitHub stars and active community validation, it's proven effective at exposing credential exposure and privilege escalation paths in workflow files that static scanners routinely miss. Skip this if your GitHub Actions usage is light or your CI/CD security program already includes runtime controls; Gato is purpose-built for teams treating pipeline compromise as a material risk, not a checkbox.
Pentesters and bug bounty hunters who need to enumerate hidden HTTP parameters fast will find Arjun indispensable; it discovers parameters that manual fuzzing misses by testing thousands of candidates against common wordlists. The 5,800+ GitHub stars and active community indicate sustained real-world adoption among practitioners who value speed over UI polish. Skip this if you need a full-featured burp suite alternative or graphical workflow; Arjun is a focused CLI tool that does one thing exceptionally well.
