Microsoft published new security extensions for Google Chrome and Mozilla Firefox

To isolate browser-based attacks, Microsoft Edge provides hardware-based isolation on Windows 10. Microsoft is now releasing this security solution as an extension for Google Chrome and Mozilla Firefox. Here’s how the Windows Defender Application Guard extension works on Chrome and Firefox:

“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 enterprise 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 enterprise-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 an enterprise site while in an isolated Microsoft Edge session, the user is taken back to the default browser.”

The new Windows Defender Application Guard extension for Google Chrome and Mozilla Firefox is available on top of the latest updated Windows 10 Professional, Enterprise and Education SKUs, and the operating system version is 1803 and higher. You can install the extension for Google Chrome or Mozilla Firefox browsers provided by Microsoft.
