Microsoft Defender for Endpoint

What is Microsoft Defender for Endpoint?

Microsoft Defender for Endpoint is a cloud-native, AI-powered endpoint security platform that helps organizations prevent, detect, investigate, and respond to cyber threats across devices like Windows, macOS, Linux, Android, iOS, and IoT systems. It provides capabilities such as endpoint detection and response (EDR), vulnerability management, attack surface reduction, and automated threat remediation, all managed from a single dashboard. By combining real-time monitoring with global threat intelligence and AI-driven insights, it helps businesses identify risks early, stop attacks like ransomware, and maintain strong, centralized security across their entire environment.

Positioned as a continuous Leader in the Gartner Magic Quadrant for Endpoint Protection Platforms (EPP) and ranking among the top detection performers across MITRE ATT&CK Enterprise Evaluations, Microsoft Defender for Endpoint protects tens of millions of enterprise devices globally. Backed by Microsoft's daily analysis of over 78 trillion cyber threat signals, Defender for Endpoint combines behavioral heuristics with cloud-delivered AI intelligence. By correlating cross-domain endpoint alerts directly with identities, email, and cloud SaaS in the unified Microsoft Defender portal, it empowers security teams to investigate and remediate complex attacks at machine speed.

• Attack Surface Reduction (ASR) Rules: Hardens system postures against common entry vectors, preventing executable content from email clients, malicious Office macros, and credential theft from LSASS.
• Defender Vulnerability Management: Continuously inventories installed software, discovers unpatched vulnerabilities (CVEs), and assigns risk scores prioritized by active exploit telemetry.
• Advanced Hunting with KQL: Search through up to 30 days of raw endpoint telemetry using Kusto Query Language (KQL) to construct custom threat detections and forensic queries.
• Microsoft Security Copilot: Generative AI natural-language assistant embedded directly in the Defender portal to summarize incidents, interpret complex scripts, and guide containment steps.
• Cross-Platform Support: Unified administration, EDR, and vulnerability assessment across Windows, Windows Server, macOS, Linux distributions, iOS, and Android.
