Windows Defender Application Guard updated for Olympia users!


Tryout the improved Windows Defender Application Guard (WDAG) using Windows Insider Lab for Enterprise (Olympia Corp). We have streamlined the setup process so now all Windows Insider devices connected to Olympia will have WDAG turned on by default. Only a system restart is required to complete the optional component install and to fully activate the feature.

With the latest update of WDAG on RS4 you will notice a marked performance improvement. For those not familiar with the feature, WDAG is a great way to ensure your device is safe from malicious web sites for both existing and emerging threats.


What is Application Guard and how does it work?

Designed for Windows 10 and Microsoft Edge, Application Guard helps to isolate enterprise-defined untrusted sites, protecting your company while your employees browse the Internet. As an enterprise administrator, you define what is among trusted web sites, cloud resources, and internal networks. Everything not on your list is considered untrusted.

If an employee goes to an untrusted site through either Microsoft Edge or Internet Explorer, Microsoft Edge opens the site in an isolated Hyper-V-enabled container, which is separate from the host operating system. This container isolation means that if the untrusted site turns out to be malicious, the host PC is protected, and the attacker can't get to your enterprise data. For example, this approach makes the isolated container anonymous, so an attacker can't get to your employee's enterprise credentials.
