Executive Summary

In the modern enterprise ecosystem, where data sprawls across cloud, hybrid, and on-premises systems, ensuring data protection, governance, and regulatory compliance has become both essential and complex. Microsoft Purview emerges as a unified governance and risk platform, purpose-built to offer visibility, control, classification, and protection of sensitive information across the entire data estate. This review explores Microsoft Purview’s functional depth, its alignment with global standards, and the practical benefits it offers to data-driven and compliance-focused organizations.

Product Overview

Microsoft Purview is an enterprise-grade data governance, compliance, and risk management platform that spans across:

• Data Discovery & Lineage (Purview Data Map)
• Classification & Labeling (MIP & Sensitivity Labels)
• Information Protection (Encryption, Rights Management)
• Regulatory Compliance Management
• Insider Risk Monitoring & DLP
• Audit & eDiscovery

Purview consolidates tools previously fragmented across Azure Purview, Microsoft 365 Compliance Center, and Microsoft Information Protection.

⚙️ Performance & Effectiveness

1. Unified Data Governance Engine

• Highly scalable metadata scanning and classification across cloud platforms (Azure, AWS, GCP) and on-prem systems.

• Integration with Microsoft Defender, Azure Policy, Power BI, and Microsoft 365 ensures operational continuity and aligned enforcement across endpoints, collaboration platforms, and data lakes.

Effectiveness Rating: ★★★★★
Key Feature: Live data maps and automated metadata harvesting ensure no data is hidden or forgotten—a major requirement for GDPR Art. 30 and ISO 27001 asset registers.

2. Information Protection & Risk Controls

• Sensitivity Labels enable structured classification per data sensitivity level: Public, Confidential, Highly Confidential, etc.
• Data Loss Prevention (DLP) policies apply natively across email (Exchange), file storage (OneDrive, SharePoint), and communication (Teams).
• Support for encryption-at-rest and rights management satisfies SOC 2, HIPAA and ISO/IEC 27001:2022 technical control standards (e.g., A.10.1 Cryptographic Controls).
