API & Integrations - Microsoft Defender for Endpoint

This article contains information on integrating Microsoft Defender with the Human Risk Platform to enhance malware behavior scoring, including setup, technical requirements, and FAQs about deployment and functionality.

Overview

The Integration with Mimecast's Human Risk and Microsoft Defender for Endpoint enhances robustness of human risk scoring by adding human interaction with malware on devices, allowing security awareness practitioners to send users training and other information based on the users' malware associated behavior.

The Integration periodically reads endpoint protection alerts from Microsoft via API. These are forwarded to the Human Risk Platform, which associates each event with a user and updates the malware behavior score for that user. Only alerts marked true positive in the Microsoft Security console will be scored.
