Gitleaks helps find secrets accidentally committed to source control. Removing a value may need to be followed by revocation and an investigation of its use.
Evaluation approach
Rules flag suspicious values. Current files, commit history and CI scans cover different scopes. Keep false-positive exceptions narrow.
Application example
If a service key appears in the application repository, revoke or rotate it as appropriate rather than only deleting the line.
Limits and considerations
A deleted secret may remain in history or a distributed package. A clean scan does not undo exposure.
What to do after finding a secret
Assess validity, access scope and where the secret may have spread. Deleting the source line alone may be insufficient. Revoke and replace credentials where necessary.
Broad exceptions can conceal real leaks. Distinguish sample values from production secrets. Reports should use safe identifiers and locations rather than republishing the secret itself.
Checks and decisions
- Review Git history
- Rotate exposed keys
- Time-limit exceptions
Treat Gitleaks findings as credential-lifecycle incidents, not just code cleanup.
