How to Measure Time to Revoke for Exposed Credentials
This is a follow-up to an article we published in The Hacker News introducing time to revoke as a critical CISO metric. This version provides a practical guide for measuring it across exposed secrets and non-human identities. 👉 TL;DR: Time to revoke is a security metric that measures how long an exposed credential remains usable after it has been confirmed valid.

Time to revoke is a crucial metric for measuring the effectiveness of security teams in handling exposed credentials. It quantifies the duration a compromised credential remains usable after initial validation. To calculate time to revoke, security teams must record two key timestamps: when the credential is initially validated and when its invalidation is confirmed.
This metric provides a more precise measurement of the exposure window, bridging the gap between detection and remediation. By tracking median and 90th percentile time to revoke, organizations can assess the typical speed of credential neutralization and identify outliers that pose significant risks. Additionally, monitoring the percentage of exposed secrets revoked within a Service Level Agreement (SLA) helps establish accountability and sets realistic expectations for remediation timelines.
Tracking the percentage of exposed secrets with confirmed owners also highlights the importance of effective identity governance and owner assignment processes. Finally, measuring the percentage of secrets incidents requiring manual escalation sheds light on process inefficiencies that can be addressed to streamline response efforts.
Implementing these metrics as part of a comprehensive secrets remediation strategy enables security teams to better assess and mitigate the risks associated with exposed credentials.
