    Windows Defender Application Guard extensions for Chrome and Firefox

    Last Updated: 20 Mar 2019 at 15:25
    To extend our container technology to other browsers and provide customers with a comprehensive solution to isolate potential browser-based attacks, we have designed and developed Windows Defender Application Guard extensions for Google Chrome and Mozilla Firefox.

    How it works

    The extensions for Google Chrome and Mozilla Firefox automatically redirect untrusted navigations to Windows Defender Application Guard for Microsoft Edge. The extension relies on a native application that we’ve built to support the communication between the browser and the device’s Application Guard settings.When users navigate to a site, the extension checks the URL against a list of trusted sites defined by enterprise administrators. If the site is determined to be untrusted, the user is redirected to an isolated Microsoft Edge session. In the isolated Microsoft Edge session, the user can freely navigate to any site that has not been explicitly defined as trusted by their organization without any risk to the rest of system. With our upcoming dynamic switching capability, if the user tries to go to a trusted site while in an isolated Microsoft Edge session, the user is taken back to the default browser.To configure the Application Guard extension under managed mode, enterprise administrators can follow these recommended steps:

    1. Ensure devices meet requirements.
    2. Turn on Windows Defender Application Guard.
    3. Define the network isolation settings to ensure a set of trusted sites is in place.
    4. Install the new Windows Defender Application Guard companion application from the Microsoft Store (ms-windows-store://pdp/?productid=9N8GNLC8Z9C8).
    5. Install the extension for Google Chrome or Mozilla Firefox browsers provided by Microsoft.
    6. Restart the devices.

    Intuitive user experience

    We designed the user interface to be transparent to users about Windows Defender Application Guard being installed on their devices and what it does. We want to ensure that users are fully aware that their untrusted navigations will be isolated and why.

    1. When users initially open Google Chrome or Mozilla Firefox after the extension is deployed and configured properly, they will see a Windows Defender Application Guard landing page.

    2. If there are any problems with the configuration, users will get instructions for resolving any configuration errors.

    3. Users can initiate an Application Guard session without entering a URL or clicking on a link by clicking the extension icon on the menu bar of the browser.

    Where to get it

    The Windows Defender Application Guard extension for Google Chrome and Mozilla Firefox is rolling out to Windows Insiders today and will be generally available very soon. This is available for users on Win 10 Enterprise and Pro SKUs on 1803 or later.

    Is it possible to view any web site via Application Guard from Chrome?

    Could this also allow M'soft the ability/excuse to track user visited sites etc whilst using Chrome and/or F'fox browsers in conjunction with Windows Defender Application Guard?
