Microsoft Defender Application Guard helps protect your device from advanced attacks by opening untrusted websites in an isolated Microsoft Edge browsing window. Using a unique hardware-based isolation approach, Application Guard opens untrusted websites inside a lightweight container that is separated from the operating system via Hyper-V virtualization technology. If an untrusted website turns out to be malicious, it remains within Application Guard's secure container, keeping the device and your device data protected. This companion to the browser extension ensures that untrusted sites open securely inside Application Guard's isolated environment. This companion app enables browsers other than Microsoft Edge to work with Microsoft Defender Application Guard.
