Microsoft Purview: Data loss prevention inline controls for prompts in Microsoft Foundry apps and agents

Microsoft Purview will enable inline data loss prevention (DLP) for prompts in Microsoft Foundry apps and agents starting mid-2026. Admins can configure DLP policies to detect and block sensitive data in AI prompts, enhancing data security and compliance with pay-as-you-go licensing and existing Purview workflows. With Microsoft Purview enabled in Microsoft Foundry, Purview admins can apply inline data loss prevention (DLP) policies to prompts used in Foundry-built apps and agents. This helps prevent sensitive data from being shared through prompts and supports stronger data protection and compliance for AI-driven workflows. This message is associated with Microsoft 365 Roadmap ID 558565. When this will happen: Public Preview: We will begin rolling out in mid-May 2026 and expect to complete by early June 2026. General Availability (Worldwide): Rollout will begin in mid-June 2026 and is expected to complete by late June 2026. How this affects your organization: Who is affected: Admins managing Microsoft Purview and Microsoft Foundry Organizations building or using apps and agents in Microsoft Foundry What will happen: When your organization builds AI apps and agents on Microsoft Foundry, Foundry admins can enable Microsoft Purview by configuring the Purview toggle in Foundry, allowing Purview to manage how these apps and agents interact with data. Security admins can ensure the data security and compliance posture of how these apps and agents interact with data by setting up DLP policies for prompts in Microsoft Purview Data Loss Prevention (DLP). Admins can configure Microsoft Purview DLP policies to evaluate prompts submitted to Foundry apps and agents. Policies can detect and help prevent the sharing of sensitive information in prompts to large language models (LLMs).. DLP enforcement occurs inline as prompts are submitted. This feature supports existing Microsoft Purview DLP capabilities and integrates with current compliance workflows. No change occurs unless admins create or enable DLP policies for this scenario (admin configuration required). Foundry-based DLP capabilities follow a pay-as-you-go model. Microsoft Purview must be enabled with a pay-as-you-go subscription for this feature to work. What you can do to prepare: Review your current Microsoft Purview DLP policies and identify scenarios that should apply to […]
