What is Microsoft Purview?
Microsoft Purview is Microsoft's unified compliance and data governance platform. It replaced Microsoft Information Protection (MIP), Azure Purview, and several standalone compliance tools under one brand in 2022.
Purview governs data across Microsoft 365 (email, SharePoint, Teams), Azure (databases, storage, AI services), and Microsoft Fabric (analytics, data science) from a single console. For regulated industries, this single-console view is critical for audit readiness.
Eight core Purview components
- Information Protection. Sensitivity labels and encryption for documents, emails, and Teams messages. Labels travel with the content — wherever it goes, the protection follows.
- Data Loss Prevention (DLP). Prevent sensitive data from leaving the organization via email, Teams, SharePoint, or endpoints. Policies can block, warn, or require business justification.
- eDiscovery. Search, preserve, collect, review, and export electronic content for legal proceedings and regulatory investigations. Standard (E3) and Premium (E5) tiers.
- Insider Risk Management. Detect and respond to risky user behaviors — data theft, policy violations, inadvertent data leaks — using machine learning signals.
- Records Management. Apply retention labels, file plans, and disposition review for regulatory recordkeeping requirements.
- Compliance Manager. Track compliance posture against 350+ regulatory frameworks. Provides an improvement score and recommended actions.
- Communication Compliance. Monitor communications for policy violations, inappropriate content, and regulatory compliance in financial services and other regulated industries.
- Data Map and Catalog. Scan and classify data sources across multi-cloud and on-premises environments. Provides business-friendly data discovery with lineage tracking.
eDiscovery: Standard vs Premium
eDiscovery lets legal and compliance teams search, preserve, collect, review, and export electronic content for legal proceedings and investigations.
eDiscovery Standard (E3)
Searches content across Exchange, SharePoint, OneDrive, and Teams. Includes legal hold capabilities and basic export. Covered by Microsoft 365 E3 licensing — no additional cost.
eDiscovery Premium (E5 or add-on)
Adds advanced capabilities required for large-scale litigation:
- Custodian management. Track and manage data subjects placed on legal hold.
- Advanced indexing. Process attachments, images with OCR, and encrypted content.
- Review sets. AI-powered document review with near-duplicate detection, email threading, and themes analysis.
- Predictive coding. Machine learning to prioritize relevant documents and reduce review time.
- Conversation reconstruction. Rebuild complete Teams and Yammer conversations for review.
DLP for regulated industries
DLP policies in Purview apply across Exchange email, Teams messages and files, SharePoint sites, OneDrive, and endpoints (Windows 10/11 devices).
Healthcare DLP configuration
For healthcare organizations, EPC Group configures DLP policies that:
- Detect PHI patterns — medical record numbers, ICD-10 codes, drug names combined with patient identifiers
- Block external email sharing of PHI unless encrypted with sensitivity label protection
- Require business justification for sharing PHI documents via Teams with external participants
- Block USB copy of PHI-labeled files on endpoint devices
- Generate incident reports for the privacy officer when PHI sharing is attempted
Financial services DLP configuration
Financial services DLP covers SEC and FINRA recordkeeping, PCI DSS card data, and SOX financial data. Policies block external sharing of material non-public information (MNPI) and flag unusual data movement patterns for the compliance team.
Insider Risk Management
Insider Risk Management detects risky behaviors before they become incidents. It correlates signals from Microsoft 365 activity — unusual downloads, emails to personal accounts, USB transfers — with HR signals like resignation dates or performance improvement plans.
The platform uses machine learning to assign risk scores. High-risk users trigger alerts. Investigators see a full timeline of activity without reading every email — the platform surfaces the relevant signals.
Common policies EPC Group deploys
- Data theft by departing employees (triggered by HR resignation signal)
- General data leaks (unusual download or external sharing volume)
- Security policy violations (access to blocked sites, unapproved software installation)
Compliance Manager
Compliance Manager maps your Microsoft 365 configuration against 350+ regulatory frameworks. It provides an improvement score from 0 to 900. Higher scores mean fewer compliance gaps.
Each framework assessment shows which controls are already met by Microsoft's platform certifications and which require customer action. EPC Group uses Compliance Manager assessments as the starting point for every compliance engagement — it shows exactly where to focus effort first.
Frequently asked questions
What is included in Microsoft 365 E3 vs E5 for Purview?
E3 includes Information Protection (sensitivity labels), basic DLP, eDiscovery Standard (content search and legal hold), and Compliance Manager.
E5 adds eDiscovery Premium, Insider Risk Management, Communication Compliance, Advanced Information Protection (trainable classifiers, exact data match), and Compliance Manager premium assessments. The E5 compliance add-on brings most E5 capabilities to E3 licenses.
How long does a Purview implementation take?
A core Purview deployment — sensitivity labels, DLP baseline, and Compliance Manager setup — runs 4–6 weeks. eDiscovery Premium configuration adds 2–3 weeks. Insider Risk Management requires 4–6 weeks for policy tuning to reduce false positives. Full Purview deployments across all eight components typically run 12–20 weeks for large enterprises.
Can Purview govern data outside Microsoft 365?
Yes. Purview's Data Map scans Azure SQL, Azure Data Lake, Amazon S3, Google Cloud Storage, SAP, and on-premises databases. Sensitivity labels can be applied to non-Microsoft content. DLP policies extend to endpoints (Windows devices) regardless of the cloud service the data moves to.
Does Purview support HIPAA compliance?
Yes. EPC Group configures Purview for HIPAA across all required controls: PHI sensitivity labels, DLP policies blocking unauthorized PHI sharing, 6-year retention policies, audit logging for PHI access, and encryption for data at rest and in transit.
Compliance Manager includes a HIPAA assessment template that tracks configuration against all required controls.
What is the difference between Information Protection and DLP in Purview?
Information Protection classifies and labels data — it answers "what is this data and who should see it?" DLP enforces policy at movement — it answers "can this data leave this context?" Sensitivity labels from Information Protection feed DLP policies.
A document labeled Highly Confidential can trigger a DLP rule that blocks it from being sent externally. Both work together.

EPC Group implements the full Purview suite for enterprises requiring unified compliance and governance across Microsoft 365 and multi-cloud data estates.
How much does Microsoft Purview cost and what licensing is required?
Microsoft Purview compliance features are included in Microsoft 365 E5 ($57/user/month) or available as add-ons. Microsoft 365 E3 ($36/user/month) includes basic DLP, retention, and sensitivity labels. The Microsoft 365 E5 Compliance add-on ($12/user/month on top of E3) adds advanced DLP, eDiscovery Premium, Insider Risk Management, Communication Compliance, and advanced audit. Individual add-ons are available: E5 Information Protection and Governance ($10/user/month), E5 Insider Risk Management ($10/user/month), E5 eDiscovery and Audit ($10/user/month). Azure Purview data governance (Data Map, Data Catalog) uses consumption-based pricing starting at approximately $0.25/capacity unit/hour. For a 5,000-user enterprise, EPC Group typically recommends M365 E5 for all users ($285K/month) as it provides the complete compliance suite plus Microsoft Defender, Entra ID P2, and Teams Premium features.
How does Microsoft Purview help with HIPAA compliance?
Microsoft Purview provides multiple capabilities that map directly to HIPAA Security Rule and Privacy Rule requirements. Sensitivity labels classify and encrypt documents containing Protected Health Information (PHI), ensuring PHI is protected at rest and in transit regardless of where the file travels. DLP policies prevent PHI from being shared via email, Teams, or SharePoint with unauthorized recipients, including blocking external sharing and requiring encryption. eDiscovery enables breach investigation and response by searching across email, Teams, SharePoint, and OneDrive for compromised PHI within minutes. Insider Risk Management detects employees downloading, printing, or transferring large volumes of patient data. Audit Premium provides 1-year audit log retention (required for HIPAA 6-year retention when exported to long-term storage) with detailed access logs for all PHI-containing files. Compliance Manager includes a HIPAA assessment template that maps specific Purview controls to HIPAA requirements, tracking your compliance posture. EPC Group has implemented HIPAA-compliant Purview configurations for over 100 healthcare organizations.
What is the difference between DLP in Microsoft Purview and traditional DLP solutions?
Microsoft Purview DLP is natively integrated across the entire Microsoft 365 ecosystem, providing unified policy enforcement across email (Exchange Online), collaboration (Teams chat and channels), file storage (SharePoint Online, OneDrive), endpoint devices (Windows and macOS), and Power BI. Unlike traditional DLP solutions (Symantec, Forcepoint, Digital Guardian) that require separate agents, proxies, and API integrations for each channel, Purview DLP uses a single policy engine that applies consistently everywhere. A single DLP policy blocking Social Security number sharing applies simultaneously to email attachments, Teams messages, SharePoint file sharing, and endpoint copy-to-USB actions. Purview DLP also leverages Microsoft 365 sensitivity labels for context-aware policies: a file labeled Highly Confidential receives stricter DLP enforcement than a file labeled General. The limitation is coverage outside Microsoft 365: Purview DLP does not monitor Slack, Google Workspace, or non-Microsoft SaaS applications. For multi-platform environments, EPC Group integrates Purview DLP with Microsoft Defender for Cloud Apps (CASB) to extend protection to 30,000+ SaaS applications.
How does eDiscovery work in Microsoft Purview?
Microsoft Purview eDiscovery enables legal and compliance teams to search, preserve, collect, review, and export electronic content for legal proceedings, regulatory investigations, and internal reviews. eDiscovery Standard (included in E3) provides content search across Exchange, SharePoint, OneDrive, and Teams with legal hold capabilities and basic export. eDiscovery Premium (E5 or add-on) adds advanced features: custodian management (track and manage data subjects), advanced indexing (processing attachments, images with OCR, and encrypted content), review sets (AI-powered document review with near-duplicate detection, email threading, and themes analysis), predictive coding (machine learning to prioritize relevant documents), and conversation reconstruction (rebuilding complete Teams and Yammer conversations). For a typical legal hold involving 50 custodians and 2 million documents, eDiscovery Premium reduces review time from 6 weeks to 1-2 weeks through AI-assisted relevance scoring. EPC Group has managed eDiscovery workflows for enterprises processing 10+ million documents for litigation and regulatory responses.
Can Microsoft Purview govern data across Azure, AWS, and on-premises sources?
Yes. Microsoft Purview Data Governance (formerly Azure Purview) provides a unified data map and catalog across multi-cloud and hybrid environments. Supported data sources include: Azure (SQL Database, Synapse, Data Lake, Cosmos DB, Blob Storage), AWS (S3, RDS, Glue), GCP (BigQuery, Cloud Storage), on-premises (SQL Server, Oracle, SAP, Teradata, file shares), and SaaS (Power BI, Salesforce, SAP S/4HANA). The Purview Data Map automatically scans these sources to discover data assets, classify sensitive information (PII, PHI, PCI), and build data lineage showing how data flows from source to consumption. Data stewards use the Data Catalog to apply business glossary terms, ownership, and quality certifications. Data Estate Insights provides aggregated dashboards showing data classification coverage, governance gaps, and sensitive data distribution across the entire estate. EPC Group implements multi-cloud Purview governance for enterprises with 500+ data sources, typically completing the initial deployment in 8-12 weeks.
