How AI describes Microsoft Defender

Microsoft Defender is an AI-powered, coordinated defense platform that prevents and disrupts threats by protecting endpoints, identity, email, apps, and cloud across an organization's digital estate. It delivers comprehensive threat prevention, detection, and response across multiple domains—including endpoint, identity, email and collaboration, SaaS, and cloud security—with offerings like Defender for Business, Defender for Office 365, and Defender for Individuals. The platform creates a living security fabric that connects signals, automates containment at the control layer, and embeds agents in workflows to accelerate threat triage and response across domains.
