Microsoft Defender XDR services: Changes to the IdentityInfo table in Advanced Hunting

Coming soon: We will unify the Microsoft Defender for Identity (MDI) and Microsoft Sentinel IdentityInfo tables in Advanced Hunting into a single table.

When this will happen: General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out early May 2025 and expect to complete by late May 2025. How this will affect your organization: After this rollout, identity-related insights will be enriched with these new columns: Column name Type Description Comment OnPremObjectId String Active Directory object ID of the user New column TenantMembershipType String User type in Microsoft Entra ID. Possible values: Guest, Member New column RiskStatus String Status of the user’s risk.
