Microsoft Defender ATP for US Government GCC High customers

Applies to:

Microsoft Defender Advanced Threat Protection (Microsoft Defender ATP) for US Government Community Cloud High (GCC High) customers, built in the US Azure Government environment, uses the same underlying technologies as Microsoft Defender ATP in Azure Commercial.

This offering is currently available to US Office 365 GCC High customers and is based on the same prevention, detection, investigation, and remediation as the commercial version. However, there are some key differences in the availability of capabilities for this offering.

Endpoint versions

The following OS versions are supported:

  • Windows 10, version 1903
  • Windows 10, version 1809 (OS Build 17763.404 with KB4490481)

  • Windows Server, 2019 (with KB4490481)

The following OS versions are not supported:

  • Windows Server 2008 R2 SP1
