Microsoft Purview brings together in one place tools that previously operated separately: cataloging, information classification, Data Loss Prevention (DLP), data lifecycle management and regulatory compliance oversight. The platform creates a consistent data security ecosystem across Microsoft 365 and Azure environments, also including support for other public clouds or on-premise systems.
With the Data Catalog module, an organization can automatically scan data sources, identify sensitive ones and build data maps. This provides a better understanding of where information is located, who has access to it and how it is used. The Information Protection module, on the other hand, automatically classifies documents and messages, assigning them confidentiality labels and appropriate protection policies, such as encryption or sharing restrictions.
