What is MTTD (mean time to detect)?
MTTD (mean time to detect) is the average elapsed time between the moment an adversary first compromises a system and the moment the security team becomes aware of the compromise, a primary measure of detection effectiveness.

Industry MTTD benchmarks for sophisticated attacks have historically been measured in weeks or months. Modern SOCs target dwell times under 24 hours for serious incidents. MTTD is influenced by detection coverage (whether tools see the attack at all), alert quality (whether the signal surfaces above noise), and triage efficiency (whether the analyst recognizes the alert as significant). Long MTTD compounds damage.
How Command Zero handles MTTD.
Command Zero's autonomous investigation of every incoming alert means signals that would otherwise be lost in Tier-1 noise are surfaced quickly. When a Tier-1 alert turns out to be the first indicator of a multi-stage attack, autonomous investigation correlates it with related signals in identity, endpoint, and email data, escalating the case as a serious incident rather than dismissing it. Customers report multi-hour to multi-day MTTD improvements on specific case types, particularly identity-driven attacks.
