Microsoft Purview Enhancements: A New Standard in Data Security and AI Governance

Microsoft’s latest round of innovations in Purview is setting a new standard for data security and governance in an era where AI touches nearly every aspect of our work lives. Announced at the upcoming Microsoft Fabric Community Conference in Las Vegas (March 31 to April 2, 2025), these advancements are poised to transform how organizations protect sensitive data and seamlessly prepare it for AI-driven insights. Here’s an in-depth look at the new features, what they mean for data security, and how these changes align with evolving regulatory requirements and industry trends.

A New Era in Data Security and Compliance​

As organizations rapidly deploy AI tools and expand their digital footprints, the risks around data exposure have never been greater. The new innovations in Microsoft Purview are designed to address these emerging challenges by integrating security, governance, and privacy into the very fabric of data management. With 75% of knowledge workers already interacting with some form of AI daily, the need for robust, compliant data control has become essential.
Key drivers behind these updates include:

• The convergence of cybersecurity and data governance responsibilities.
• An evolving regulatory landscape, with over 1,000 AI-related policy initiatives across 69 countries.
• The growing necessity to safeguard sensitive data, especially in environments that include guest users and third-party access.

These trends compel companies to rethink their approach to data security. Microsoft Purview’s latest enhancements do just that by enabling a more unified view of data risk and facilitating proactive management to ensure data remains protected across all touch points.

Enhancing Data Loss Prevention for the Lakehouse​

One of the cornerstone updates is the enhanced Data Loss Prevention (DLP) support specifically designed for lakehouse environments within Microsoft Fabric. Traditionally, DLP policies have served as the backbone of Microsoft 365’s data security strategy. Now, Purview extends this capability to the boundless realm of enterprise data stored in lakehouses.
Highlights of the new DLP enhancements include:

• • Proactive restriction of guest access when sensitive data is detected.
• • Flexible configuration options for security administrators, allowing policies to restrict data access only to internal users or designated data owners.
• • Real-time notifications for users working with sensitive data, enabling immediate corrective actions through policy tips.

In practice, these updates mean that if a Fabric tenant includes guest users, any attempt to access personally identifiable information (PII) stored within a lakehouse can trigger a restriction. This is instrumental in preventing accidental data leakage and ensuring that only trusted parties are granted access to critical information.
By restricting guest user access in scenarios where PII is identified, Microsoft Purview helps organizations confidently maintain compliance without sacrificing the agility required for modern data exploration and AI innovation.

Summary Points​

• Enhanced DLP support offers real-time notifications and restrictions.
• Guest user access is curtailed when sensitive data is detected.
• Administrators enjoy flexible policy configurations to suit varied security needs.

Expanding DLP Policy Support Across Fabric Environments​

Beyond lakehouses, Microsoft Purview is significantly expanding its DLP policy support to encompass additional critical components of the Microsoft Fabric ecosystem. These enhancements are particularly focused on:

• KQL Databases: The only databases used for real-time analytics in Fabric now benefit from sensitive data detection. With the ability to generate policy tips when sensitive data is manipulated in real time, Fabric customers can promptly identify and mitigate potential data breaches.
• Mirrored Databases: These include data layers from Azure Cosmos DB, Azure SQL Database, Azure SQL Managed Instance, Azure Databricks Unity Catalog, and even Snowflake. Enhanced policy tips here alert users whenever sensitive data is accessed or transferred, thereby reducing risks associated with data movement across platforms.

Why is this expansion so crucial? Simply put, it extends end-to-end data protection across more entry points in the Microsoft Fabric environment. This comprehensive coverage means that whether your organization is performing real-time analytics or synchronizing data across cloud services, the same robust security policies apply.

In Practice:​

• Administrators can now monitor sensitive data interactions in both real-time analytics and traditional database environments.
• More granular control and visibility translate to fewer gaps in data governance.
• The expanded policy tip mechanism not only educates users by notifying them of potential risks, but also helps ensure that data handling practices remain compliant with the latest regulations.

Summary Points​

• DLP now covers KQL and Mirrored databases within Fabric.
• Policy tips guide users in real-time, preventing inadvertent data exposure.
• Expanded monitoring ensures end-to-end data protection across multicloud environments.

Introducing Microsoft Purview for Copilot in Fabric​

As organizations race to harness the power of AI, integrating data security within AI platforms becomes imperative. This is why one of the most exciting previews announced is Microsoft Purview for Copilot in Fabric, starting with its integration in Power BI.
This integration brings together data governance and AI to create a secure environment where insight generation and data protection go hand in hand. Key capabilities include:

• Detection of Sensitive Data in AI Interactions: Purview now identifies when sensitive data is mentioned in user prompts or AI responses. This detection feeds into the Microsoft Purview Data Security Posture Management (DSPM) dashboard, offering actionable recommendations to minimize data risks.
• Risk Alert Mechanisms: By leveraging Purview Insider Risk Management, administrators can monitor and investigate risky AI usage. Whether it’s an inadvertent disclosure by a careless employee or a departing user trying to extract sensitive data via AI tools, the system provides alerts and investigation pathways.
• Governance via Audit and eDiscovery: Integration with audit tools, along with retention policies and non-compliant usage detection, ensures that all AI interactions are governed under a Zero Trust framework. This greatly reduces the possibility of data breaches or non-compliant AI behavior.

The convergence of Purview with Copilot in Power BI means that as organizations strategize around AI, they do so with a robust safety net ensuring that data privacy and security are never compromised.

Benefits for AI-Driven Organizations:​

• Proactive risk management through continuous monitoring.
• Seamless integration of governance, ensuring AI outputs rely on secure, high-quality data.
• Improved compliance with regulatory standards through actionable insights from the DSPM dashboard.

Summary Points​

• Purview for Copilot bridges the gap between AI and data security.
• Real-time detection and alerting ensure that sensitive data remains protected during AI interactions.
• Comprehensive risk management and governance measures accompany the AI tools.

Unlocking Data Observability with the Unified Catalog​

Data quality is a non-negotiable element in AI innovation. Recognizing this, Microsoft Purview now offers Data Observability within its Unified Catalog—a preview feature that residents of the multicloud and hybrid data estate will find indispensable.
This new capability enables users to:

• Visually Trace Data Lineage: Understand how different data assets relate to one another, including how data flows across governance domains, data products, and glossary terms.
• Identify Root Causes of Data Quality Issues: When data quality problems arise, Purview’s lineage view helps pinpoint the exact origins and pathways of these issues.
• Ensure Trustworthy AI: By maintaining high data quality, organizations can confidently rely on the data that fuels their AI systems, ultimately ensuring more reliable and actionable insights.

The ease with which administrators can navigate the Unified Catalog to identify and correct data quality issues means that regulatory reporting and compliance become significantly less burdensome. In an age where data is a strategic asset, this observability feature not only improves data quality but also builds trust in AI-driven outcomes.

Summary Points​

• The Unified Catalog offers a comprehensive data lineage view.
• Quick identification of data quality issues ensures faster resolution.
• Enhanced data observability supports regulatory requirements and trustworthy AI.
