Microsoft Defender Network Protection - Not Enabling via Intune - Troubleshooting & Fix

Sun, 07 Mar 2021 13:27:29 +0000

When configuring Defender for Endpoint (MDE) customer recently, I ran into a problem when trying to enable network protection. Network protection is a feature of MDE and Microsoft Defender Antivirus (MDAV) that takes the filtering capabilities of SmartScreen and applies them to all network traffic. It is a prerequisite for things such as MDE’s web content filtering and URL/domain indicators of compromise.

This blog details the specific problem I had enabling it with Intune (Microsoft Endpoint Manager), and general troubleshooting steps to follow that will help for that problem and hopefully others you may experience.
