What it is
Microsoft Purview: Data Loss Prevention - File Testing Against Sensitive Information Classifiers is a Microsoft 365 roadmap item published via Microsoft Release Communications. Current status: Launched.
What it does
A new feature will be introduced on the main Classification page, allowing users to test files against all available classifiers to identify the presence of sensitive information. Users will have the option to select a single classifier or run tests across all classifiers. This capability is designed to help users identify sensitive content within files and troubleshoot classification issues more efficiently.
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. Decide: adopt for a named cohort, defer, or reject. If adopting, update licence and adoption plans in the same week.

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.
