Apply your organization’s security policies to protect internet traffic when your device is managed by the organization.
Provide secure access to work apps and data using Zero Trust controls.

Terrible App. It is mandatory to have an outlook account to continue. I have an outlook/hotmail account but after entering email address, the screens keep stuck on loading or white screen. If somehow it manages to go forward, it asks for Device Registration, upon accepting, indefinite Loading........... Pretty frustrating. Uninstalling right away!

Microsoft Defender app is easy to use and sends out alerts whenever a security risk detected or personal information is exposed. I feel Microsoft Defender security is better than Google, considering my Google accounts were hacked several times and so much data was deleted . Microsoft Defender web protection on a man 9lon phone constantly being turned off and I have been unable to determined why, and almost daily have to switch it back on frustrating.Stii can't locate the VPN settings

it's more Microsoft garbage making an effort to help but just makes a mess of things. Do I trust what Microsoft brings to the table? No, not in the lease bit. Do I have to go back and constantly fix Microsoft screw ups in the OS system? Yes, all the time. Does Microsoft make things better? Only in very small ways but screws it all up after a few service upgreads. I only recommend Microsoft products because it's so mainstream now and not much competition.
