Network Protection is a new security feature of Windows Defender that Microsoft introduced in the Fall Creators Update for its Windows 10 operating system.
It extends Windows Defender SmartScreen by blocking outbound (HTTP and HTTPS) traffic connecting to resources that have a low reputation.
The feature is part of Windows Defender Exploit Guard, and it requires that Windows Defender is turned on, and that the security program's real-time protection feature is enabled as well.
System administrators and users may configure the Network protection feature of Windows Defender using policies, PowerShell or MDM CSPs.
