Mandiant Report: Breach Dwell Time Climbs to 14 Days, Edge Devices Are the Blind Spot
shashib · x · 2026-07-31
Mandiant's latest report reveals that the global median breach dwell time rose to 14 days in 2025, breaking a decade-long trend of steady improvement.
The report emphasizes that this isn't primarily due to AI-wielding attackers, but rather edge devices like routers, VPNs, and firewalls lacking deep logging capabilities. This blind spot allows long-term潜伏, pushing back against AI security vendors' marketing claims that AI drastically cuts response times.
