View untrusted websites in a separate Microsoft Edge browsing window to help protect your device from advanced threats.
Windows Defender Application Guard Extension protects your device from advanced attacks by redirecting untrusted websites to an isolated version of the Microsoft Edge browser. If an untrusted website turns out to be malicious, it remains within Application Guard's secure container, keeping your device protected.
Windows Defender Application Guard Extension works with the following editions of Windows 10, version 1803 with latest updates or later:
Windows 10 Professional
Windows 10 Enterprise
Windows 10 Education
NOTE: If you're using Windows 10 in an unmanaged environment, you can use this extension to manually open untrusted websites in an isolated Application Guard session, but untrusted websites will not be redirected automatically.
