Windows Defender Application Guard is designed for Windows 10 and Microsoft Edge to isolate enterprise-defined untrusted sites to help you protect your system from malicious attacks. Using this hardware isolation approach, you can destroy the loophole that attackers use.

 

Where security is key concern, you should enable the Windows Defender Application Guard on your Windows 10 system and safely browse the internet using Microsoft Edge browser.

When the Windows Defender Application Guard is enabled, if you browse the internet using the Microsoft Edge browser and you reach to an untrusted site, Microsoft Edge opens the site in an isolated Hyper-V-enabled container, which is separate from the host operating system. This container makes sure that, if you reach to an untrusted site and that site is malicious, the host system stays protected due to the hardware isolation. This protects your system from the attackers as they can't reach to your data due to this isolation.

 

Which devices can be configured to use Application Guard?

You can protect all your Windows 10 devices by turning ON the Windows Defender Application Guard. Be it your personal or enterprise grade desktops, laptops or a mobile device having Microsoft Edge as your internet browser. For an optimal performance, Microsoft recommends 64-bit system with a minimum 4 cores logical processor, 8 GB RAM and at least 5 GB hard drive free space on your desktop or laptop to enable Application Guard.

 

If you are using any VM or VDI environment, the Windows Defender Application Guard is not supported in those virtual systems.
