How To Implement A Data Governance Program With Azure Purview
Microsoft Purview (formerly Azure Purview) is the unified data governance platform that enables enterprises to discover, classify, and govern data assets across on-premises, multi-cloud, and SaaS environments from a single control plane. As organizations face mounting regulatory pressure (HIPAA, GDPR, CCPA, SOC 2) and struggle with data sprawl across hundreds of systems, Purview provides the automated discovery, sensitivity labeling, and lineage tracking needed to establish a scalable data governance program. EPC Group has implemented Microsoft Purview for enterprises across healthcare, financial services, and government, designing governance frameworks that balance compliance rigor with operational agility.
Why Data Governance Matters Now
Data governance is no longer an optional discipline -- it is a regulatory, operational, and strategic imperative:
- Regulatory Compliance: HIPAA, GDPR, CCPA, SOC 2, and industry-specific regulations require organizations to know what data they hold, where it resides, who can access it, and how it flows through systems. Non-compliance penalties can reach 4% of global revenue (GDPR) or $1.5M per violation category (HIPAA).
- AI Readiness: Generative AI and Copilot adoption amplify the need for governance. Without knowing what data exists and how it is classified, organizations risk exposing sensitive data through AI-powered search, chat, and document generation.
- Data Quality: Ungoverned data leads to duplicated, stale, and inconsistent datasets that undermine analytics and decision-making. Data governance establishes stewardship, quality rules, and accountability.
- Merger and Acquisition Integration: M&A activity requires rapid discovery and classification of acquired data assets. Purview automates what would otherwise take months of manual catalog work.
Microsoft Purview Platform Overview
Microsoft Purview consolidates multiple governance capabilities into a unified platform:
- Data Map: Automated scanning and discovery of data assets across Azure (SQL, Storage, Synapse, Data Lake), on-premises (SQL Server, Oracle, SAP), multi-cloud (AWS S3, Redshift; GCP BigQuery), and SaaS (Power BI, Salesforce, Dynamics 365). The Data Map creates a living inventory of all data assets with technical metadata, schema details, and classification tags.
- Data Catalog: A searchable business glossary and catalog that enables data consumers to find, understand, and trust data assets. Business users search for datasets using natural language, view data profiles and samples, and request access through integrated workflows.
- Data Estate Insights: Dashboards and reports showing data asset distribution, classification coverage, sensitivity label adoption, and governance health metrics across the entire data estate.
- Data Lineage: End-to-end visualization of how data flows from source systems through ETL pipelines (Azure Data Factory, Synapse, Databricks) to analytics and reporting layers. Critical for impact analysis, debugging, and regulatory audit trails.
- Sensitivity Labels: Unified labeling across Microsoft 365, Azure, and on-premises data sources. Labels flow from Purview Information Protection into the Data Map, ensuring consistent classification regardless of where data is stored.
- Data Access Governance: Policy-based access controls that enforce who can access which data based on classification, sensitivity, and business context. Integrates with Azure RBAC, SQL permissions, and storage ACLs.
Step-by-Step Implementation Guide
EPC Group follows a structured methodology for implementing data governance with Microsoft Purview:
- Phase 1: Governance Framework Design (Weeks 1-3). Define governance objectives, roles (Data Owner, Data Steward, Data Consumer), policies, and success metrics. Establish a data governance council with executive sponsorship. Map regulatory requirements (HIPAA, GDPR) to specific governance controls.
- Phase 2: Purview Deployment and Configuration (Weeks 2-4). Provision the Microsoft Purview account, configure networking (private endpoints for on-premises scanning), set up integration runtimes, and establish role-based access. Configure the business glossary taxonomy aligned with your organization's data domains.
- Phase 3: Source Registration and Scanning (Weeks 3-6). Register data sources (Azure, on-premises, multi-cloud), configure scan credentials (managed identity, service principal, key vault), and execute initial full scans. Validate discovered assets and classification results. Tune classification rules for industry-specific data types (PHI, PII, financial data).
- Phase 4: Business Glossary and Stewardship (Weeks 4-8). Populate the business glossary with standard terms, definitions, and relationships. Assign data owners and stewards to cataloged assets. Create and publish data policies covering access, quality, and retention.
- Phase 5: Lineage and Impact Analysis (Weeks 6-10). Configure lineage extraction for Azure Data Factory, Synapse pipelines, Databricks notebooks, and Power BI datasets. Validate end-to-end lineage from source to consumption layer. Use lineage for impact analysis of planned schema changes.
- Phase 6: Operationalization (Weeks 8-12). Establish recurring scan schedules, stewardship workflows, data quality monitoring, and governance health dashboards. Train data owners and stewards on Purview tools and governance processes. Integrate Purview alerts with ServiceNow or Jira for issue tracking.
Purview for Compliance-Heavy Industries
EPC Group specializes in implementing Purview for organizations with stringent regulatory requirements:
- Healthcare (HIPAA): Automated discovery and classification of PHI (Protected Health Information) across EHR databases, data lakes, and analytics environments. Sensitivity labels enforce access controls and DLP policies. Lineage tracks PHI flows for HIPAA audit requirements.
- Financial Services (SOC 2, PCI DSS): Classification of financial data, PII, and cardholder data across trading systems, CRM databases, and reporting platforms. Access governance enforces least-privilege access to sensitive financial datasets.
- Government (FedRAMP, FISMA): Data cataloging and classification aligned with NIST 800-53 controls. Purview deployed in Azure Government regions with private endpoints to meet FedRAMP High authorization requirements.

Frequently Asked Questions
What is the difference between Azure Purview and Microsoft Purview?
Azure Purview was the original name for the data governance product launched in 2020. In 2022, Microsoft rebranded it as Microsoft Purview and expanded the platform to include compliance, risk, and information protection capabilities alongside the original data governance features. The data governance capabilities (Data Map, Data Catalog, Data Estate Insights) remain the same. The broader Microsoft Purview platform now also encompasses Information Protection, Data Loss Prevention, Insider Risk Management, eDiscovery, and Communication Compliance.
What data sources does Purview support scanning?
Microsoft Purview supports 100+ data source connectors including: Azure (SQL Database, Synapse, Storage, Data Lake, Cosmos DB), on-premises (SQL Server, Oracle, SAP HANA, Teradata, MySQL, PostgreSQL), multi-cloud (AWS S3, Glue, Redshift, RDS; GCP BigQuery, Cloud Storage), SaaS (Power BI, Salesforce, SAP ERP, Dynamics 365), and file-based sources (ADLS Gen2, Blob Storage, file shares). Custom connectors can be built for sources not covered by the built-in connectors.
How does Purview handle sensitive data classification?
Purview uses built-in classification rules powered by machine learning and pattern matching to automatically detect over 200 sensitive data types including Social Security numbers, credit card numbers, medical record numbers, passport numbers, and custom patterns specific to your organization. You can also create custom classification rules using regex patterns or dictionary-based matching. Classification results are applied as labels in the Data Map, and sensitivity labels from Microsoft Purview Information Protection are synchronized for consistent labeling across Microsoft 365 and Azure.
How long does a Purview implementation take?
A foundational Purview deployment (platform provisioning, initial source registration, scanning, and basic governance framework) typically takes 8-12 weeks. A comprehensive implementation including business glossary, stewardship processes, lineage mapping, access governance policies, and change management takes 4-6 months. EPC Group recommends a phased approach: start with high-priority data sources and compliance-critical assets in Phase 1, then expand coverage and governance maturity over subsequent phases.
What are the costs of Microsoft Purview?
Microsoft Purview data governance pricing is based on Data Map capacity units (which determine scanning throughput and metadata storage), number of scans, and optional advanced features. The Data Map starts with a minimum capacity for small environments and scales based on data estate size. Data Catalog search and browsing are included. Purview Information Protection and compliance features are licensed through Microsoft 365 E5 or as standalone add-ons. EPC Group provides detailed cost modeling based on your data estate size, scan frequency, and governance scope.
