Microsoft Entra at RSAC 2026 unveiled identity and network security updates to protect human and AI agent identities, extend Zero Trust to web and AI traffic, enable passkeys and external MFA, detect shadow AI and prompt injection, add tenant governance and backup, and strengthen risk-based access.
Microsoft announced Microsoft Entra innovations at RSAC 2026 that extend identity protection to AI agents and multi-tenant environments. These updates unify identity, network access, and agent protections to strengthen Zero Trust posture.
Main feature/change and impact
The core change is Entra treating agents as first-class identities alongside users and devices. Agent ID provides unique agent identities, enabling governance, conditional access, and lifecycle controls. Tenant Governance and Backup and Recovery improve resilience for complex, multi-tenant deployments. These features reduce attack surface and simplify enforcement of least-privilege access across human and non-human identities.Practical implications
Security teams must onboard agent identities and apply existing identity controls. Conditional Access can make real-time decisions for agents and users using shared signals. Shadow AI detection and prompt injection protection block risky AI traffic. Passkeys, external MFA, and adaptive remediation enable passwordless and phishing-resistant authentication at scale. Recovery and cross-tenant sync reduce operational risk and speed incident recovery.“The latest Microsoft Entra innovations advance this vision, so you can protect access for people and agents and strengthen your Zero Trust posture. With those new capabilities you can: Protect agent identities with the same rigor as users, apps and devices.”Microsoft Entra now emphasizes identity fabric, continuous signal sharing, and automated enforcement across identities and sessions. Organizations should plan agent onboarding, update Conditional Access policies, and validate backup and tenant governance. Prioritize deployment of passkeys and shadow AI controls to reduce attack vectors and support a secure AI-enabled environment.
