What this shortlist looks at

Detection Accuracy

Ability to detect real secrets while minimizing false positives, including coverage of custom secret formats beyond standard API key patterns.

Pre-Commit Prevention

Capability to block secrets before they're committed to version control, preventing the leak rather than detecting it after the fact.

CI/CD Integration

Quality of integration with CI/CD pipelines for automated scanning of every commit, pull request, and build artifact.

Historical Scanning

Ability to scan full git history and commit logs to find secrets that were committed and later removed but still exist in version history.

Remediation Workflow

Tools for rotating compromised credentials, notifying affected teams, and tracking remediation progress across the organization.

SplitSecure

Best Prevention-First Approach

SplitSecure eliminates the secret scanning problem at its root. If credentials are split across devices and no complete secret exists in any single location, there's nothing to leak to source code. For organizations tired of playing whack-a-mole with secret scanning findings, SplitSecure removes the problem architecturally.

Distributed secrets management. No vault, no vendor dependency

Frequently Asked Questions

Secret scanning detects credentials that have leaked into source code or other unauthorized locations. Secrets management provides a secure system for storing and distributing credentials properly. You need both. Management prevents leaks, and scanning catches what slips through.

Yes. Pre-commit hooks prevent secrets from entering the repository, and CI/CD scanning catches anything the hooks miss. Historical scanning should also be run periodically to find secrets in older commit history that predate your scanning tools.

Immediately rotate the credential, then remove it from the code. Simply deleting the secret from the latest commit isn't sufficient. It remains in git history. The credential must be considered compromised and rotated regardless of how quickly it's removed from code.
