What is Application Guard? How to create a secure web environment

Recently on Windows 11, Microsoft developed a Sandbox version for Microsoft Edge called Microsoft Defender Application Guard.

What is Application Guard?

Using Windows 10 you will probably know Windows Sandbox, the feature of creating a separate virtual environment for the system to install and test unstable or unsafe programs.

You can open untrusted, even dangerous websites in Microsoft Edge under the protection of Microsoft Defender Application Guard. Basically, you can now open suspicious websites in isolated mode. Even files you download in windows protected by Microsoft Edge Application Guard will be kept isolated from system files.

In addition to the main advantage, Microsoft Defender Application Guard is also noted for performance issues. When you use it, it will not affect the system. However, there are some hardware requirements for this, and if you see the feature option greyed out, your computer isn’t enough. It also doesn’t slow down the system and the Microsoft Defender Application Guard window opens as fast and smooth as a regular browser window. The only difference is the isolation.

How to use Microsoft Defender Application Guard

By default, Microsoft Defender Application Guard is not enabled. You will have to activate it manually when using it.
