What is Mean Time to Respond in Cybersecurity?
A cybersecurity operations metric measuring the average time from incident detection to the completion of response actions that stop the attack and begin recovery. MTTR encompasses investigation, containment, eradication, and initial recovery steps. A shorter MTTR reduces the window attackers have to cause damage after being detected.
Why Mean Time to Respond Matters for Your Cybersecurity Career
MTTR is the metric that shows how quickly a security team can act once a threat is found. SOC analysts and incident responders drive this metric through their investigation speed and playbook execution. Security engineers reduce MTTR by building automation and SOAR workflows. CISOs use MTTR trends to justify staffing and tool investments.
