What it is
Microsoft Purview: Insider Risk Management – Reduce temporary file noise for Endpoint activities in IRM is a Microsoft 365 roadmap item published via Microsoft Release Communications. Current status: In development.
What it does
When files are opened in Windows, the operating system, and applications (for example, Microsoft Office and browsers) can create, rename, and delete temporary files as part of normal behavior. The Endpoint client audits these activities, resulting in high-volume, low-signal events that appear as “noise” for Insider Risk Management (IRM) customers. While global exclusions exist (file type, keyword, file path, etc.), some temporary file naming patterns are not easily captured with the current exclusions, leaving customers without a practical way to reduce noise without over-excluding. This feature introduces built-in filtering for well-known temporary file name patterns so that Endpoint file operations are excluded from IRM activity explorer and scoring reducing noise allowing customers to focus on the most relevant alerts. Microsoft Purview Insider Risk Management correlates various signals to identify potential malicious or inadvertent insider risks, such as IP theft, data leakage, and security violations. Insider Risk Management enables customers to create policies based on their own internal policies, governance, and organizational requirements. Built with privacy by design, users are pseudonymized by default, and role-based access controls and audit logs are in place to help ensure user-level privacy.
Why you should care
Board
Security/compliance control — fund Steady before more seats.
CISO
Prioritise as Steady control; wire into IR and GRC evidence paths.
CFO
Map licence or consumption impact to the frozen value case; avoid seat spray.
Adoption
Pilot with a named cohort and measure changed work, not vanity clicks.
Suggested action
Wave 0 first: Security → GRC → Cost & Value → Licence → Adoption. Add to Horizon watchlist with an owner. Pilot only after Steady controls for the affected surface are in place.
12 Panes: 03 Horizon · 04 Security · 05 GRC · 08 Adoption
Communication needed
- Security: Lead review; confirm control mapping before enablement.
- GRC: Update AI/agent register and evidence path; confirm DPIA triggers if personal data is in scope.
- FinOps: Forecast seat or credit impact; align to frozen value case.
- Adoption: Plan cohort messaging, clinics, and success measures.
- Comms: One story for board and staff — what changes, what does not, who owns risk.
Benefits
- May improve productivity on a specific Microsoft 365 surface when permissions and data quality allow.
- Roadmap visibility helps Horizon planning without guessing dates.
Risks
- Status and dates change; treat MRC as directional, not a contract.
- Enabling without Steady controls can amplify overshare or cost leakage.
- Preview or rolling features can change behaviour; fence exploration on Pane 12 Frontier.
