Enforce compliance requirements for your data without hindering productivity with Purview Data Loss Prevention

In her retail headquarters office, the regional director shares sales projections in Teams and a Policy Tip prompts her to apply an internal-only sensitivity label before she clicks Send.

What is Microsoft Purview Data Loss Prevention?

Microsoft Purview DLP is a cloud-native service that applies one set of data-protection rules across Microsoft 365 apps, Windows and macOS devices, on-prem file shares, and even AI assistants such as Microsoft 365 Copilot. From a single compliance portal you can discover sensitive data, classify it with built-in or custom definitions, and choose how users may share, copy, print, or export it. The result: reduced breach exposure, demonstrable regulatory compliance, and a security posture that adapts to hybrid work without slowing it down.

What can you do with Microsoft Purview Data Loss Prevention?

Modern data loss prevention can’t rely on a single control point—it has to follow your information wherever it moves. The capabilities below show how Microsoft Purview DLP weaves protection directly into your cloud apps, endpoints, and AI tools, giving security teams unified control without slowing business momentum.

Unified policy management

Author a rule once and enforce it everywhere: Exchange Online, SharePoint, OneDrive, Teams, endpoints, and sanctioned SaaS apps discovered through Defender for Cloud Apps.

Content-aware detection

Leverage 300+ sensitive-information types and trainable classifiers that recognize context such as source code, resumes, or legal briefs—not just credit-card patterns.

Risk-adaptive controls

Integrate with Purview Insider Risk Management to escalate from a user warning to an automatic block when behavior crosses a risk threshold.

In-context guidance

Policy tips appear inside Outlook, Word, Excel, PowerPoint, and Teams to teach users safe handling at the moment of action while still allowing a justified override when business demands it.

AI-ready safeguards

Prevent Microsoft 365 Copilot from processing or outputting content that carries restricted sensitivity labels, keeping tomorrow’s AI workflows as protected as today’s email.

How can Purview Data Loss Prevention help your organization?

During a board-level huddle, Purview DLP honors the “Highly Confidential” label on strategy briefs in SharePoint, preventing downloads to an unmanaged tablet yet allowing on-screen review. While executives swap Excel forecasts, Purview DLP scans OneDrive in real time and blocks external sharing of any sheet that contains customer PII, keeping collaboration internal.

Reduce breach impact and accelerate response

Microsoft Purview DLP blocks risky actions the moment they occur—whether that is a user copying a client file to USB, forwarding sensitive email externally, or an insider downloading volumes of IP. Each violation is logged, correlated, and surfaced in Microsoft Defender XDR, so security analysts see the user, device, and content context in one place. This saves hours of manual triage and lets teams contain incidents quickly, limiting legal exposure, customer notification costs, and reputational fallout.

Compliance analysts at a healthcare insurer run a HIPAA template simulation in the Purview portal, previewing the effect of new rules on outbound email before activating them company-wide.

Turn compliance into strategic value

Purview DLP auto-discovers regulated data such as PCI, HIPAA, or CPRA records, applies the correct sensitivity label, and enforces policy wherever that data travels. Detailed evidence is captured in the Microsoft 365 audit trail, giving auditors a ready-made record of due diligence. By automating discovery and proof of control, organizations divert fewer resources to manual reviews and instead focus on using insights from the compliance dashboard to shape new data-driven initiatives.

Employees continue working without disruption as governance staff publish updated DLP rules—the cloud-native engine applies the changes instantly, with no device restarts required. Adaptive controls tied to Purview Insider Risk Management keep everyday access smooth, yet auto-escalate to block mass downloads if user behavior suddenly looks risky. Colleagues crowd around a laptop and use Word’s Apply Sensitivity button; Purview DLP binds the label to the document so every future email or upload respects its protection level.

Keep work flowing through continuous change

Because Purview DLP’s policies live in the cloud, protection follows data as business units adopt new SaaS tools, integrate AI copilots, or bring acquired teams onto the network. Policy tips and override workflows guide employees in real time, allowing legitimate collaboration while preventing accidental leaks. The result is an environment where mergers, expansions, and technology rollouts proceed on schedule—without waiting for separate security projects to catch up.
