Microsoft is deprecating Defender Application Guard for Edge for Business users.
Microsoft Defender Application Guard blocks potential threats by opening them in a secure sandbox using hardware-based virtualization.
"Microsoft Defender Application Guard, including the Windows Isolated App Launcher APIs, is being deprecated for Microsoft Edge for Business and will no longer be updated," Microsoft announced.
Redmond advises customers to check out the Microsoft Edge For Business security whitepaper for more details on the security capabilities that still ship with its Edge for Business web browser.
Last month, Redmond announced that it's deprecating Defender Application Guard for Office, including the Windows Security Isolation APIs.
The announcement came two years after Redmond rolled out Application Guard for Office to all Microsoft 365 customers with eligible licenses and four years after its introduction as part of a limited preview in November 2019.
