Pre-commit review is a security or quality check performed before code is saved into a shared repository, such as Git. It can be manual, automated, or both, and it usually looks for bugs, secrets, unsafe dependencies, or suspicious logic while changes are still local. Because the code has not yet been merged, defects are cheaper to fix and less likely to spread through builds, tests, and downstream releases.
In cyber security, pre-commit review helps stop common attack paths such as hardcoded credentials, vulnerable library updates, insecure deserialization, and accidental exposure of internal endpoints. Defenders use hooks, linters, secret scanners, and AI-assisted analysis to catch risky patterns early. It is especially useful in larger teams, where a small mistake can quickly become a shared supply-chain problem. A pre-commit review does not replace human judgment, but it reduces the chance that dangerous code enters the repository in the first place.
