TruffleHog covers the same ground as Gitleaks with one decisive addition: verification. For hundreds of credential types it calls the provider's API to check whether the key still works, which collapses a page of findings into the handful that are actually live.

That distinction is the difference between a report someone triages and a report someone acts on today.

• Separating live credentials from long-dead ones
• Scanning an organisation's repositories at once
• Prioritising rotation by what is verifiably still valid
