The commit stopped cold. A single check had flagged it before it could touch the main branch. No human had triggered the test—only the non-human identity assigned to the automation pipeline.
Non-human identities have become a critical part of software delivery chains. They are service accounts, CI/CD bots, deployment agents, and infrastructure scripts. They hold permissions, push code, and interact with secured systems without human hands on the keyboard. Their speed and scale are unmatched—but without safeguards, they can ship mistakes or malicious changes faster than any developer.
Pre-commit security hooks are the control point. They run in your local environment or CI pipeline before a commit is accepted. For non-human identities, these hooks enforce policies: scanning for secrets, checking code for vulnerabilities, validating config files, and blocking unsafe commits before they move downstream.
