Microsoft Purview DLP Policy

Microsoft Purview Data Loss Prevention (DLP) detects and prevents risky sharing, transfer, or use of sensitive data across Microsoft 365 services and Windows/macOS endpoints - anchored to the Zero Trust Data pillar.

When to use

Stopping exfiltration of sensitive content (PII, financial, IP, regulated data) across email, collaboration, and endpoints with a defensible, tunable policy set.

Do not use this skill for risk-adaptive DLP keyed to Insider Risk (use purview-advanced-dlp) or for Copilot-specific exclusion (use purview-copilot-oversharing).
