Work out time to remediate instantly with clear inputs, formula shown and shareable results.
Mean time to remediate is the sum of three distinct stages, and treating it as one number hides where the delay actually is. Waiting for a vendor fix is outside your control; triage delay reflects process and staffing; deployment delay reflects change management and automation maturity. Only the last two are yours to shorten, so the bottleneck breakdown matters more than the total.
MTTR decomposition
MTTR = detection-to-triage + triage-to-fix + fix-to-deploy; bottleneck = largest stage as a share of the total
Both, separately. Time from public disclosure measures your exposure window; time from your own detection measures your process efficiency.
Automated patch pipelines with staged rollout and automated rollback. Manual change approval boards are usually the single largest contributor to deployment lag.
