Microsoft Defender ATP runs on macOS Mojave, High Sierra, and Sierra, with updates managed through Microsoft's AutoUpdate software. By supporting Defender on macOS, it allows a business to still decide to use Microsoft's security tools without the hassle of integrating some other security software just for Macs. Microsoft Defender ATP exists because Microsoft realized organizations operate a whole range of devices and not all of them run Windows. Today, it helps protect Windows 10 as Windows Defender Antivirus.

For Windows 8, Microsoft developed it into a full antivirus solution where it replaced Microsoft Security Essentials. Windows Defender started life as an anti-spyware solution for Windows XP you could download before it became a permanent part of Windows Vista and Windows 7.
