Microsoft Purview: Data Security Investigations – role-based access simplification

Microsoft Purview will simplify Data Security Investigations access by automatically adding the DSI Contributor role to key role groups, effective late April 2026. No action or opt-in is needed, but admins should review role memberships to ensure appropriate access and update documentation if necessary. Introduction We’re simplifying how organizations manage access to Data Security Investigations (DSI) in Microsoft Purview. Based on customer feedback and continued alignment with Data Security Posture Management (DSPM), Insider Risk Management (IRM), and Microsoft Defender XDR, the DSI Admin and DSI Contributor roles will automatically be included in additional role groups. This reduces manual assignments and helps teams that frequently work across these solutions have the right access by default. This message is associated with Microsoft 365 Roadmap ID 558546. When this will happen General Availability (Worldwide): Rolling out in late April 2026 and expected to complete by late April 2026.
