API description

Isolates a device from accessing external network.


  1. Rate limitations for this API are 100 calls per minute and 1500 calls per hour.


This page focuses on performing a machine action via API. See take response actions on a machine for more information about response actions functionality via Microsoft Defender for Endpoint.


  • Full isolation is available for devices on Windows 10, version 1703, and on Windows 11.
  • Full isolation is available in public preview for all supported Microsoft Defender for Endpoint on Linux listed in System requirements.
  • Selective isolation is available for devices on Windows 10, version 1709 or later, and on Windows 11.
  • When isolating a device, only certain processes and destinations are allowed. Therefore, devices that are behind a full VPN tunnel won't be able to reach the Microsoft Defender for Endpoint cloud service after the device is isolated. We recommend using a split-tunneling VPN for Microsoft Defender for Endpoint and Microsoft Defender Antivirus cloud-based protection-related traffic.
