MTTR
MTTR (Mean Time to Respond/Recover) is a key measurement used in cybersecurity to track how quickly a company can detect and fix security problems. Think of it like measuring the response time of emergency services - the faster the response, the less damage occurs. When you see this on a resume, it usually refers to someone's ability to help organizations respond to security incidents quickly and effectively. This term might appear as either "Mean Time to Respond" or "Mean Time to Recover" - both are important metrics that show how well a security team performs during incidents.
Examples in Resumes

Led team initiatives that improved Mean Time to Respond by 75% through better alert prioritization
Established baseline Mean Time to Recovery metrics and improved response protocols
