Simple definition
Microsoft Purview is a portfolio of Microsoft solutions for data governance, data security, and data compliance.
Technical definition
Purview spans several capability areas. Governance helps inventory, catalog, and understand data; security includes capabilities such as Information Protection and DLP; compliance includes Audit, eDiscovery, Data Lifecycle Management, and Records Management. Available features depend on the services and licenses in use.
What is it used for?
Identify important data, apply classification and protection, reduce data leakage, retain or delete information according to policy, and support audit or investigation requirements.
Practical example
An organization applies sensitivity labels to confidential documents, creates a DLP policy to prevent certain data from being shared externally, and uses eDiscovery when a regulatory or legal search is required.
Common issues
- Required capability is outside the current license or scope
- Sensitivity labels or DLP policies target the wrong users or locations
- Purview role is insufficient for an investigation
- Retention rules conflict or are misunderstood
Key takeaway: Purview is not a single feature; it is a portfolio that spans data governance, protection, and compliance.
