Defender ATP Block Mode 🛡️⚔️

It’s called “endpoint detection and response (EDR) in block mode,” the capability is meant to provide post-breach blocking of malware and other malicious behaviors, by taking advantage of Microsoft Defender ATP’s built-in machine learning models.

EDR in block mode aims to detect threats through behavior analysis, providing organizations with real-time protection, even after a threat has been executed. It aims to help companies respond to threats faster, thwart cyber-attacks, and maintain security posture.

To block the attack, EDR in block mode stops processes related to the malicious behaviors or artifacts. Reports of these blocks are shown in Microsoft Defender Security Center, to inform security teams and enable further investigation, as well as the discovery and removal of similar threats.

Now available in public preview, EDR in block mode has already proven effective in stopping cyber-attacks. In April, the tech giant says, the capability blocked a NanoCore RAT attack that started with a spear-phishing email that had as attachment an Excel document carrying a malicious macro.

Microsoft customers who already turned on preview features in the Microsoft Defender Security Center can enable EDR in block mode by heading to Settings > Advanced features.

The tech giant encourages customers who preview EDR in block mode to provide feedback on their experience with the behavioral blocking and containment capabilities in Microsoft Defender ATP.
