MTTD: Mean Time to Detect in Cybersecurity
MTTD stands for Mean Time to Detect. MTTD measures the average time between when a threat first appears in the environment and when the security team identifies it. Lower MTTD reduces attacker dwell time and limits damage.
How MTTD Is Used in Cybersecurity
SOC analysts track MTTD to evaluate how quickly their detection tools and processes catch threats. Threat intelligence analysts work to lower MTTD by tuning detection rules and adding new indicator feeds. CISOs benchmark MTTD against industry averages to assess program maturity.
