Mean Time to Recover (MTTR)

Reviewed byCybersecurity entrepreneur & security researcher

What is Mean Time to Recover (MTTR)?

Mean Time to Recover (MTTR)The average time required to restore affected systems and services to normal operation after a security incident or outage.


MTTR (recover) tracks the full restoration phase: rebuilding compromised systems, recovering data from backups, validating integrity, re-enabling user access and confirming business operations are healthy. Unlike containment, it focuses on returning to a steady-state production posture rather than merely stopping the attacker. It is closely tied to RTO and RPO and depends heavily on backup quality, disaster-recovery design, automation, runbook completeness and supplier responsiveness. Tracking MTTR per incident class and per critical service highlights where infrastructure brittleness or dependency on manual work prevents the organization from meeting agreed recovery objectives.

  2. 02
