Microsoft released this week browser extensions that port the Windows Defender Application Guard technology from Edge to Chrome and Firefox.
The extensions only work for Chrome and Firefox running on current Windows Insider builds, but are expected to work with the upcoming Windows 10 stable release, 19H1, scheduled for release later this spring.
The Windows Defender Application Guard technology is a relatively new Windows Defender security feature that until now has only been available to Edge users.
According to a Microsoft help page, Windows Defender Application Guard lets enterprise administrators set up a list of trusted websites and local resources that the user can access using Edge.
If the user accesses an URL that is not on this list, Windows Defender Application Guard comes into effect and starts a sandboxed session of Edge (an Hyper-V-enabled container) where the new website will be loaded in a safe environment isolated from the rest of the Edge browser and underlying operating system.
This way, any potential attack won’t be able to reach and grab the user’s data, or plant malware on the local operating system.
