Foundations of Data Security and Compliance with Microsoft Purview: Technical Overview
In the era of digital transformation, securing sensitive data and ensuring compliance with legal and regulatory frameworks is a strategic priority for modern enterprises. Microsoft addresses this challenge through its unified solution Microsoft Purview, which combines capabilities for data security, compliance, information governance, and risk management within Microsoft 365 environments.
This article expands upon the key concepts covered in the Microsoft Learn module, offering a technical and market-oriented analysis of Microsoft’s approach to information protection and compliance.
What Is Microsoft Purview?
Microsoft Purview is an integrated platform that delivers data governance, compliance, and risk management across your entire data estate. It supports organizations in:
- Discovering and classifying sensitive data
- Applying protection policies and labels
- Monitoring regulatory compliance
- Managing insider risks and external data sharing
- Auditing and responding to incidents
It unifies Microsoft 365 compliance features with Azure-based data governance and lineage tools to deliver a consistent compliance posture across hybrid and multi-cloud environments.
Core Technical Capabilities
1. Data Classification and Sensitivity Labels
Microsoft Purview provides built-in and custom classifiers that scan data across Microsoft 365 workloads, such as Exchange Online, SharePoint Online, OneDrive, and Microsoft Teams.
- Built-in sensitive info types: credit card numbers, national IDs, medical data, etc.
- Custom sensitive info types: regex or keyword-based rules
- Trainable classifiers: AI-powered models that learn based on labeled examples
- Sensitivity labels: metadata applied to content to enforce protection such as encryption or watermarking
2. Information Protection Policies
Using Microsoft Purview Information Protection, organizations can:
- Encrypt files and emails (via Microsoft Information Protection and Azure Rights Management)
- Restrict access based on user roles or groups
- Automatically apply labels via policies
- Integrate with Microsoft Defender for Cloud Apps for advanced control
3. Data Loss Prevention (DLP)
Microsoft 365 DLP policies prevent unintentional sharing of sensitive information by monitoring:
- Email traffic
- SharePoint/OneDrive file activity
- Teams chat messages
- Windows 10/11 endpoint behavior (via Microsoft Endpoint DLP)
DLP actions include warnings, blocking transmission, and notifying admins or users.
4. Information Governance
Purview enables classification of content for lifecycle management and regulatory compliance:
- Retention policies and labels
- Auto-application of retention rules
- Regulatory record designation
- Event-based retention triggers
This helps reduce risk, optimize storage, and ensure legal hold where required.
5. Insider Risk Management and Audit
Microsoft Purview Insider Risk Management uses machine learning to detect risky behavior by employees or contractors, such as:
- Unauthorized downloads
- Data exfiltration
- Use of shadow IT
Audit logs provide visibility across user and admin actions, with long-term retention available for eDiscovery.
Integration and Ecosystem
Microsoft Purview integrates with:
- Microsoft Defender for Endpoint for endpoint data protection
- Microsoft Sentinel for SIEM integration
- Azure Purview (now part of Microsoft Purview) for structured/unstructured data discovery
- Power BI for data lineage and access control
This ecosystem supports zero trust architecture, with multi-cloud visibility, and compliance with frameworks like ISO 27001, NIST, GDPR, LGPD, HIPAA, and CCPA.
Market Perspective
Microsoft Purview is positioned as a leader in enterprise compliance platforms, as recognized by analysts such as Gartner and Forrester. It competes directly with:
- Google Workspace DLP and Vault
- Symantec DLP (Broadcom)
- Forcepoint Data Protection
- Proofpoint
- Varonis (for insider risk and file analysis)
Its differentiation lies in deep integration with Microsoft 365, AI-powered data classification, and extensive compliance coverage.
