Windows Defender Advanced Threat Protection is aimed at helping businesses deal with serious threats by using machine learning to protect Windows 10 devices. The feature builds a profile of how a computer behaves, and then alerts IT managers if it starts acting in a way that’s indicative of a security breach. Microsoft hasn’t decided which versions of Windows 10 will be usable with the feature, or what sort of business model will underpin it. Right now, it’s in a private preview with a set number of organizations, securing about 500,000 devices.”]
