What it is
Microsoft Purview: Data Loss Prevention - Extend Purview data security to the network layer via Entra GSA integration is a Microsoft 365 roadmap item published via Microsoft Release Communications. Current status: Rolling out.
What it does
Extend Microsoft Purview data security controls to the network layer to detect and protect sensitive data in text and prompts by integrating with Entra Internet Access. This integration enables organizations to intercept and inspect text and AI interactions at the network layer, enforce restrictive actions based on DLP policies, and detect risky user activity through Insider Risk Management. It helps prevent sensitive data from being shared with untrusted cloud applications through browsers, apps, APIs, add-ins, and more - including generative AI platforms, social media, collaborative platforms - while managing alerts and incidents through Purview and Microsoft Defender.
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.

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.
