About

Microsoft Defender is Microsoft's comprehensive endpoint security platform — providing antivirus, anti-malware, endpoint detection and response (EDR), vulnerability management, and attack surface reduction across Windows, macOS, Linux, iOS, and Android devices. Part of Microsoft's Security portfolio (which generates $20+ billion annually), Microsoft Defender for Endpoint has become one of the most widely deployed enterprise security products as organizations already licensing Microsoft 365 E5 gain enterprise security capabilities that previously required separate vendor relationships with Symantec, CrowdStrike, or SentinelOne.
