2026 Threat Landscape Report: the year breakout time fell below an hour
Guardian Labs analysed 4.2 trillion weekly security events and 1,180 incident response engagements to measure how quickly intrusions now spread. Median breakout time — the interval between initial compromise and the first lateral movement — fell to 41 minutes, down from 62 the previous year. The report breaks the number down by sector, initial access vector and adversary category, and sets out what a defensive programme has to change to stay ahead of it.
