What scanners look for
Secret scanners combine known prefixes, high-entropy strings, assignment patterns, key blocks, and provider-specific checks. They can catch common API tokens and credentials but will produce both misses and false alarms.
Human review still matters
A database hostname, internal ticket number, customer record, or signed URL may be sensitive without looking like a conventional secret. Review the meaning of the data, not only its character pattern.

If a secret was pasted
Treat public exposure as compromise. Delete the paste, revoke or rotate the credential at its issuer, inspect audit logs, and update any dependent systems. Deletion alone is not remediation because copies and crawlers may exist.
Key takeaways
- Automated scanning is a guardrail, not a guarantee.
- Review contextual and personal data too.
- Rotate exposed credentials immediately.
