+## Data Policy
+A set of central, cloud-based experiences that help you manage access to data sources and datasets securely and at scale.
+Benefits:
+* Structure and simplify the process of granting/revoking access
+* Reduce the effort of access provisioning
+* Enhanced security:
+   - Easier to review access/revoke it in a central vs. distributed access provisioning model
+   - Reduced need for privileged accounts to configure access
+   - Support Principle of Least Privilege (give people the appropriate level of access, limiting to the minimum permissions and the least data objects)
+
+For more information, see our introductory guides:
+* [Data owner access policies](concept-policies-data-owner.md): Provision fine-grained to broad access to users and groups via intuitive authoring experience.
+* [Self-service access policies](concept-self-service-data-access-policy.md): Self-Service: Workflow approval and automatic provisioning of access requests initiated by business analysts that discover data assets in Microsoft Purview’s catalog.
+* [DevOps policies](concept-policies-devops.md): Provision access to system metadata for IT operations and other DevOps personnel, supporting typical functions like SQL Performance Monitor and SQL Security Auditor.
