Microsoft Entra November 2025 Identity Security Updates
Summary
Microsoft’s November 2025 Entra updates focus on expanding identity security for AI agents and generative AI apps, including new preview features like Entra Agent ID, Prompt Shield for prompt injection protection, and improved passkey recovery. The release also matters for IT admins because it introduces important security hardening changes—such as stricter sign-in page content security policies and device integrity checks in Microsoft Authenticator—that may require action to avoid disruption.
Introduction: why this matters
Microsoft Entra’s November 2025 updates reinforce a clear theme: identity security must extend to AI agents, modern authentication, and safer sign-in surfaces. For IT admins, the month brings new previews to govern agents and protect GenAI apps, while also introducing security hardening and lifecycle/API changes that may impact existing workflows.
What’s new (highlights)
AI-era identity & agent governance
- Microsoft Entra Agent ID (Public Preview): New capabilities to manage, govern, and protect AI agents as part of the Agent 365 control plane.
- Security Copilot included in Microsoft 365 E5: Expands access to Copilot experiences in Entra and the new Entra agents, making advanced security assistance available to more administrators.
- Entra Suite Prompt Shield (Public Preview): Helps protect enterprise GenAI applications against prompt injection attacks.
- Synced passkeys + self-service account recovery (Public Preview): Improves adoption of phishing-resistant auth with broader recovery options across authentication methods.
Microsoft Entra ID: security and admin experience changes
- Block external script injection during Entra ID sign-in (Action may be required): Entra ID rolled out a stricter Content Security Policy (CSP) on
login.microsoftonline.comto prevent unauthorized script execution and reduce XSS risk. - Jailbreak/Root detection in Microsoft Authenticator (Action may be required): Starting February 2026, Authenticator will disable and wipe Entra credentials on jailbroken/rooted devices (iOS and Android). No admin configuration is required.
- Replace “Revoke MFA sessions” with “Revoke sessions” (Action may be required): Starting February 2026, the portal action will invalidate all user sessions (including MFA), aligning behavior across Conditional Access and per-user MFA.
Governance, External ID, and network access updates
Entra ID Governance
- New capabilities including external user conversion to internal members, SCIM 2.0 SAP CIS connector (with group provisioning), eligible group memberships/ownerships in Entitlement Management, and improvements to Lifecycle Workflows (reprocessing failures, sensitivity label support, triggers for inactive employees/guests).
- PIM API deprecation (Action may be required): The Iteration 2 (beta) PIM API will stop returning data on October 28, 2026. Migration to Iteration 3 (GA) APIs is recommended.
Entra External ID
- Regional expansion to Australia and Japan, plus simplified Azure Monitor/Sentinel setup for external tenants and additional fraud/WAF integrations.
Global Secure Access
- New integrations such as GSA + Netskope ATP/DLP and Internet Access TLS Inspection.
Impact for IT administrators
- Expect sign-in flow compatibility testing needs due to CSP tightening (especially if extensions or tools inject scripts).
- Plan for Authenticator behavior changes on compromised devices and potential support tickets when users are blocked.
- Update operational runbooks for session revocation to avoid misunderstanding the new “Revoke sessions” behavior.
- Start API modernization efforts if you rely on PIM iteration 2 endpoints.
Recommended next steps
- Test sign-in flows across browsers and managed endpoints; remove/replace any tools that inject scripts into Entra sign-in pages.
- Notify end users ahead of February 2026 about Authenticator jailbreak/root detection and required remediation.
- Update helpdesk/admin documentation to use Revoke sessions and document its broader impact.
- Begin PIM API migration planning now; stop new development on iteration 2 APIs and validate iteration 3 compatibility.
- Evaluate previews (Agent ID, Prompt Shield, passkeys recovery) in a controlled pilot to assess governance and security fit.
