#DefenderForEndpoint
Over the last couple weeks, I've been mapping out the internal APIs for Defender for Endpoint for use with automation

I just finished the last of the MDE settings and pushed PowerShell examples so anyone can automate configuration of the MDE service 🥳

I often complain about how you can't target MDE device groups with AV, Firewall, ASR rules, and other policies, especially for MDE settings management

Thanks to @Eric_K_Morrison, I created an Azure Automation to sync MDE device groups with Entra groups :)

I am very excited to announce I have published the first revision of my automated MDE service configuration script using the internal service APIs

Next I'll add automated AV/ASR/FW config in Intune and add better error handling and logging, then Maester!

In case anyone is interested, here's a script to gather Defender logs and create a performance recording, then compress it and upload it to Azure blob storage

This works via Live Response, Intune scripts, etc. Just need Create permissions on a SAS token.

Eventually this could be a PS module for all of Defender XDR, but I'm waiting for some changes first :p

Microsoft Defender for Endpoint is previewing automatic isolation for compromised devices, limiting lateral movement and speeding incident containment while keeping endpoints connected for monitoring. #Microsoft #DefenderEndpoint #AttackDisruption
Microsoft Defender can now automatically isolate hacked endpoints
Microsoft is testing a new Defender for Endpoint capability that can automatically isolate compromised devices to stop lateral movement and reduce the impact of attacks. The preview feature keeps isolated endpoints connected to Microsoft Defender for Endpoint for monitoring and is part of automatic attack disruption. #Microsoft #DefenderforEndpoint
