Microsoft is now bringing Windows Defender Advanced Threat Protection (ATP) to non-Windows devices. To reflect this change, Microsoft is rebranding the service as Microsoft Defender ATP. Microsoft Defender ATP on Mac can run on devices running macOS Mojave, macOS High Sierra, or macOS Sierra. During the preview period, Microsoft Defender ATP for Mac will allow end users to review and perform configuration of their protection, including:

• Running scans, including full, quick, and custom path scans (we recommend quick scans in nearly all scenarios)
• Reviewing detected threats
• Taking actions on threats, including quarantine, remove, or allow
