A cybersecurity operations metric measuring the average time between when a security incident begins and when the organization first identifies it. MTTD is calculated across all incidents over a reporting period. Lower MTTD indicates faster detection capabilities, which typically correlates with less damage from breaches and more effective security monitoring programs.
MTTD is a key performance indicator that CISOs report to boards and executives. SOC analysts contribute directly to reducing MTTD through alert triage speed and investigation quality. Security engineers who build better detection rules and automate alert enrichment measurably lower this metric. Knowing how to track and improve MTTD shows operational maturity.
