128 Seconds to disruption: Microsoft Defender stops ransomware at QNET

Microsoft Defender's new device isolation feature automatically contains compromised endpoints by blocking external network connectivity when the system detects a high-confidence threat. In a case study at QNET, the feature isolated a ransomware attack in 128 seconds, preventing the attacker from establishing persistence or spreading beyond the infected host. The capability addresses a shift in attack patterns where adversaries establish local footholds on devices rather than immediately moving laterally across the network.

Why it matters: Security teams using Microsoft Defender for Endpoint gain an autonomous containment mechanism that can stop endpoint-focused ransomware attacks without manual intervention, reducing the window of exposure from minutes to seconds and limiting lateral movement risk.
