How to Measure Time to Revoke for Exposed Credentials
GitGuardian, Tuesday, July 21st, 2026
Time to revoke measures how long an exposed credential stays usable after its validity is confirmed.
The article introduces time to revoke as a security metric for CISOs, defined as the interval between the validation timestamp and confirmed invalidation.
Organizations should track median and P90 time to revoke, the percentage of secrets revoked within SLA, owner coverage, and the number of incidents requiring manual escalation.
These measurements help security teams shrink exposure windows by separating detection from actual credential neutralization, addressing the limitations of traditional MTTD and MTTR metrics.
