What is MTTR (mean time to respond)?

MTTR is sometimes called "mean time to remediate" or "mean time to resolve" depending on the organization. The metric measures how fast the SOC can act on a known threat: scoping the affected systems, identifying the adversary's actions, containing the attack, and beginning recovery. MTTR is bounded by investigation speed at the front end and operational complexity at the back end. Reducing MTTR is one of the highest-leverage SOC improvements.

Command Zero compresses the investigation phase of MTTR. When an incident is confirmed, expert investigation questions run in parallel across all data sources, replacing what would otherwise be sequential manual queries. Customers report sub-hour resolution on routine cases that historically took half a day. For incident response specifically, the audit trail produced during investigation feeds directly into response decision-making, so containment can begin while investigation continues.
