Microsoft's enterprise data security and compliance platform that provides comprehensive governance, protection, and risk management for AI applications including Microsoft 365 Copilot, Security Copilot, and other generative AI tools.
Microsoft Purview for AI is a Security & Privacy enterprise governance platform that provides comprehensive data security, compliance, and risk management for AI applications including Microsoft 365 Copilot, Security Copilot, and third-party generative AI tools, with pricing available through Microsoft 365 E5 enterprise licensing. It targets large enterprises, regulated industries, and IT security teams that need to safely deploy generative AI without leaking sensitive data or violating compliance mandates.
Built on Microsoft's broader Purview compliance suite, the platform combines three pillars: Data Security Posture Management (DSPM) for AI, which surfaces risky AI prompts and oversharing risks; sensitivity-label-aware protections that travel with AI-generated content; and Communication Compliance plus eDiscovery integrations that capture Copilot interactions for regulatory review. Administrators can detect when employees paste confidential information into ChatGPT, Google Gemini, or DeepSeek, apply Data Loss Prevention (DLP) policies that block restricted prompts, and audit every Copilot response across Microsoft 365. The platform supports more than 300 sensitive information types out of the box and integrates with Microsoft Defender for Cloud Apps to govern over 100 generative AI services.
Compared to the other Security & Privacy and AI governance tools in our directory of 870+ AI tools, Microsoft Purview is uniquely positioned for organizations already standardized on Microsoft 365 and Entra ID â its protections extend natively into Copilot, Outlook, Teams, and SharePoint without additional connectors. Standalone competitors like Nightfall AI, Lakera Guard, or Prompt Security may offer faster deployment for non-Microsoft stacks, but Purview's deep integration with Microsoft 365 E5 entitlements, Insider Risk Management, and Compliance Manager makes it the de facto choice for Fortune 500 IT teams already managing 10,000+ seat Copilot rollouts.

A unified dashboard that surfaces risky AI interactions across Microsoft 365 Copilot and 100+ third-party generative AI apps. It highlights sensitive data exposures, oversharing risks, and high-risk users in near real time, and links each signal back to the underlying prompt, user, and source document for one-click remediation.
Microsoft Information Protection labels applied to source documents are automatically inherited by Copilot-generated content such as summaries, emails, and Word drafts. Encryption and usage rights travel with the AI output, so a 'Confidential' source file produces a 'Confidential' Copilot response â preventing inadvertent declassification.
Purview Data Loss Prevention policies extend to Copilot and to browser-based interactions with external AI tools. Admins can block, warn, or audit when 300+ built-in sensitive information types â credit cards, source code, health records â are submitted as prompts to ChatGPT, Gemini, or DeepSeek, with policy tips shown to end users.
Every Copilot prompt and response is logged in the user's Exchange mailbox, making it searchable through eDiscovery (Premium) and reviewable via Communication Compliance. Legal teams can place AI interactions on hold for litigation, while compliance teams use ML classifiers to flag harassment, insider trading, or regulatory violations in AI conversations.
Purview correlates Copilot usage anomalies â large-scale prompts about customer data, summarization of sensitive HR files, off-hours Copilot activity â with existing insider risk signals from Microsoft 365 and Entra ID. Adaptive Protection can then automatically tighten DLP and access policies for high-risk users without manual intervention.
