Mean Time to Recover (MTTR) is a key metric in cyber security that measures the average time it takes for an organization to respond to, repair, or recover from a cyber incident, such as a breach, vulnerability, or system failure.

MTTR is crucial in evaluating the effectiveness and agility of incident response teams, as well as the resilience of security systems.

A shorter MTTR indicates that an organization can mitigate threats faster, reducing potential damage and downtime, while a longer MTTR may signify weaknesses in detection, response protocols, or recovery strategies.
