Last week we shipped Maester 2.3. Here's the walk-through.
The big one: The new Affected objects blade. Every user, group and app behind your failed checks, in one view.
@Thomas_Live built it and explains why, plus a quick tour of the rest, in 6 min.
GA of service-to-service token binding is announced in Entra’s October “What’s new”. Initial release: #ManagedIdentities on #Azure Trusted Launch or Confidential VMs/VMSS, for KeyVault. Can’t wait for more supported scenarios for NHIs in #MicrosoftEntra:

I joined Dinant Paardenkooper on "AzSecurity - Learn by doing" to share the story behind #EntraOps including live demos: Classification Model, Classification Explorer & reporting integrations for a practical Enterprise Access Model in #MicrosoftEntra.

🤔 Why should the AI Administrator role in #MicrosoftEntra be considered Control Plane (Tier 0)? At first glance, it might seem particularly privileged just to manage #AgentIdentities. But there's an aspect that often gets overlooked. (1/7) 👇
🛡️ The EntraOps Classification Explorer makes this classification visible and documented. We've also covered the AI Administrator role, its permissions, and associated risks in our new Attack & Defense Playbook chapter on Microsoft Entra Agent Identity. (6/7)

Together with @samilamppu, @RobbeVdDaele, and @DerkvanDerWoude, I’ve been researching #AgentID foundations, attack scenarios, detections, and mitigations.
We’ve also started publishing the Attack & Defense Playbook as a dedicated website.
You can now explore it at:

#MDDR 2026 is out – a must-read for everyone in #MicrosoftSecurity. Password spray still leads by volume, but post-authentication attacks keep gaining ground: token theft shows up as a distinct post-compromise tactic. Check out the full report:

🤖 🔑 New chapter of the #MicrosoftEntra Attack & Defense Playbook coming soon!
6+ months of research with @samilamppu, @RobbeVdDaele and @DerkVanDerWoude on #AgentIdentities:
🥷 Potential attack scenarios
🔎 Detection & reporting
🛡️ Mitigation & delegation
Early next week 👀
While researching #MicrosoftEntra Identity Governance, I found a permission-expansion path via Catalog Owners and API permissions. Reported to MSRC and fixed. My write-up covers the scenario, why and how you should monitor your catalogs with #EntraOps:
