Service principals worked for static apps, but AI agents are different—they make autonomous decisions using LLMs and require a new approach to identity and security.

In this episode of Entra Chat, Padma Parthasarathy, Product Manager for Microsoft Entra Agent Registry, explains why Microsoft created Entra Agent Registry and Agent ID, and how they provide identity, governance, and security for AI agents.

We cover agent collections, discovery policies, integration with identity protection, and how custom security attributes automate AI agent governance at scale. You’ll also see how agents discover other agents by skills, how global and quarantine collections control visibility, and why these capabilities are critical for enterprise AI security.

This is a must-watch (listen) for identity, security, and platform architects preparing for AI at scale.
