Microsoft Defender Antivirus – Schedule & Install Updates via Network Shares

Although not common, there are scenarios out where you will have LAN-only devices onboarded in Microsoft Defender for Endpoint (MDE), or at least using Microsoft Defender Antivirus (MDAV). With no line of sight to the internet, you can use options such as WSUS, but in this blog, I'll explore using a network share, as WSUS isn't always an option. Set up the network share for updates 1.

Microsoft Defender for Endpoint Web Content Filtering – Administration, Limitations, and User Experience

Historically, one of the big features missing "out of the box" with MDATP was web content filtering.
