MTTR is a metric that measures the average time it takes to respond to or resolve an incident, from detection to resolution. In security, it captures how quickly a team contains and recovers from an attack; in operations, how fast it restores a failed service. A lower MTTR means faster recovery and less damage.
MTTR is one of a family of related metrics, alongside mean time to detect (MTTD) and mean time to acknowledge (MTTA). Tracking each separately shows whether your bottleneck is noticing the problem or fixing it.
In a breach, MTTR maps directly to cost: the longer an attacker dwells, the more data is exposed and the larger the cleanup. Preparation, clear runbooks, and a retainer with a named responder are what actually move the number down.
traztech delivers incident response that lowers MTTR for startups and growth-stage companies, led by a published CVE researcher.
