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. If someone within the network goes to an untrusted site through either Microsoft Edge, Internet Explorer, etc., the site is opened in an isolated Hyper-V-enabled container, which is separate from the host operating system. Everything not on your list is considered untrusted. As an enterprise administrator, you have the power to define what is among trusted web sites, cloud resources, and internal networks.
