To learn more about Domains – REST API (Admin), and Domains, refer to the documentation.

Microsoft Purview Protection Policies for Fabric (Generally Available)

Microsoft Purview protection policies provide a powerful and automated way to enforce data governance and security within Microsoft Fabric. These policies leverage sensitivity labels from Microsoft Purview Information Protection to automatically restrict access to sensitive data assets, like Lakehouses or KQL databases, within Fabric. Instead of manually configuring access controls for every data item, organizations can define a single policy that applies a specific level of protection to all data with a given sensitivity label.

By integrating directly with Fabric, these policies allow you to apply granular controls, like blocking access for all but a select group of users, ensuring that only authorized individuals can interact with your most critical data. This automated and centralized approach reduces the burden on data engineers and IT admins, enabling them to focus on building data solutions while the platform handles the enforcement of security and compliance standards.

Refer to the Protection policies in Microsoft Fabric (preview) documentation to learn more.

Default Sensitivity Label for Domains (Generally Available)

Once defined, these labels apply automatically to all new items created in the specified domain, allowing you to use a centralized configuration to reduce human error and ensure consistent data handling across the organization.

Refer to the Domain-level default sensitivity labels documentation to learn more.

Microsoft Purview Data Loss Prevention Policies for Fabric (Generally Available)

In Microsoft Fabric, Data Loss Prevention (DLP) policies are a game-changer for organizations by acting as a proactive defense for sensitive data. These policies automatically identify and protect confidential information—such as personally identifiable information (PII), financial data, or intellectual property—as it’s created or moved within the Fabric environment, including semantic models and structured data in OneLake, such as Lakehouses, mirrored databases and more. This capability is critical for ensuring compliance with various regulations like GDPR and HIPAA, and it helps to prevent costly data breaches that can lead to significant financial loss and reputational damage. By providing real-time alerts to administrators and policy tips to users, DLP policies empower a culture of security awareness and reduce the risk of both accidental and malicious data leaks.

With this release we are announcing the general availability of DLP policies for your OneLake data, which means businesses can embed data security directly into their data workflows, moving beyond reactive measures to a more secure, proactive posture.
