In Windows 10 Insider Preview BuildAnnouncement of 18358Microsoft has indicated that it has developed and started testing a Windows Defender Application Guard extension for Chrome and Firefox. Microsoft designed and developed the extension for Google Chrome and Mozilla Firefox in order to extend its container technology to other browsers and provide users with a comprehensive solution to isolate potential browser-based attacks.


Windows Defender Application Guard automatically redirects untrusted web pages to Windows Defender Application Guard for Microsoft Edge. This extension relies on native apps to support browsers and devicesApplication Guard settingsCommunication between.

When a user navigates to a site, the extension checks the URL against a list of trusted sites defined by the enterprise administrator, and if it determines that the site is not trusted, it redirects the user to a quarantined Microsoft Edge session. In an isolated Microsoft Edge session, users are free to navigate to any site that is not trusted without any risk to the rest of the system.

That is to say, Chrome or Firefox is used, and if you want to use the Windows Defender Application Guard feature, you need to use an Edge session at the same time.

Officials also said that in the upcoming dynamic switching feature, if a user tries to go to a trusted site in a quarantined Microsoft Edge session, the user is taken back to the default browser.

To use this feature, you must have the Windows Defender companion app and the corresponding browser extension installed. Since it is still in preview mode, only Insiders is currently available.
