What is Microsoft Purview?

Microsoft Purview is Microsoft’s unified compliance, governance, and data protection platform for Microsoft 365 and hybrid environments.

Microsoft Purview helps organizations:

• Discover sensitive data
• Classify information
• Protect business data
• Manage records
• Monitor risks

Purview combines multiple compliance and governance solutions into a centralized platform.

Why Microsoft Purview Matters

Modern organizations face growing challenges:

• Regulatory compliance
• Data leakage
• Insider threats
• Information sprawl

Without centralized governance:

• Sensitive data becomes difficult to control
• Compliance risks increase
• Investigations become slower
• Regulatory violations become more likely

Microsoft Purview helps organizations centralize compliance operations across Microsoft 365 workloads.

Compliance vs Security Explained

This is one of the most important MS-102 concepts.

Security and compliance work together but serve different purposes.

Microsoft Defender protects systems.

Microsoft Purview protects and governs information.
