The Mean Time to Patch (MTTP) gap is the growing window between when a vulnerability is publicly disclosed and when it is fully remediated across all affected endpoints in your environment.
As the volume of Common Vulnerabilities and Exposures (CVEs) increases and attackers move faster, traditional processes—like periodic scanning and manual change windows—tend to extend that exposure window instead of shrinking it.
It’s important to distinguish two key metrics:
- MTTP (Mean Time to Patch)
Measures how long it takes from vulnerability disclosure to full remediation across endpoints. It’s a leading indicator of your exposure window and cyber risk posture.
- MTTR (Mean Time to Resolution)
Measures how long it takes to fully resolve an IT incident once detected, including diagnosis, remediation, recovery, and verification. It’s a broader operational efficiency metric.
Historically, many state and local environments have operated with 15–30 day patch cycles for critical vulnerabilities. The playbook frames these timelines not as best practice, but as artifacts of legacy tooling limitations.
A modern, unified platform should aim to:
- Compress MTTP from ~30 days to under 72 hours.
- Reduce MTTR by 50% or more.
To close the MTTP gap without increasing operational risk, the playbook recommends:
- Real-time endpoint telemetry instead of periodic scans and registry remnants.
- Policy-based automation for low-risk patches, with full audit trails.
- Risk-based prioritization using signals like patch sentiment and scaled deployment telemetry to avoid unstable updates.
- Unified workflows that connect detection directly to remediation, so exposure doesn’t persist after issues are “reported.”
For government IT leaders, closing the MTTP gap is about rethinking patching from a slow, calendar-driven process to a faster, risk-driven, and automated capability that measurably reduces cyber exposure.
