Frequently Asked Questions
What is Microsoft Purview and what does EPC Group deploy?
Microsoft Purview is Microsoft's unified data governance platform covering sensitivity labels, audit, eDiscovery, retention, insider risk management, communication compliance, data loss prevention, and information protection across Microsoft 365, Azure, and Copilot. EPC Group deploys all eight Purview capabilities — starting with a Readiness Assessment that maps your current data classification gaps, then designing the sensitivity label taxonomy, deploying DLP policies, configuring audit retention, and integrating Copilot oversharing controls.
How does Microsoft Purview prevent Copilot data oversharing?
Microsoft Purview sensitivity labels are applied to SharePoint sites, OneDrive folders, Teams channels, and individual documents. When Microsoft 365 Copilot grounds a response, Purview enforces the sensitivity label boundary — Copilot will not surface Confidential content to users without explicit label permission. EPC Group's Copilot oversharing assessment audits your existing sensitivity label coverage, identifies gaps, and deploys auto-classification rules to close them before Copilot deployment.
How much does Microsoft Purview consulting cost?
EPC Group Microsoft Purview Readiness Assessment runs $25,000-$75,000 fixed-fee over 4-6 weeks. Full Purview deployment with sensitivity label architecture, DLP policies, audit retention configuration, and Copilot oversharing controls typically runs $100,000-$300,000 over 12-24 weeks depending on tenant scale, regulatory environment, and Copilot integration scope. Managed Purview services are available at $7,500-$15,000 per month for ongoing governance, label drift monitoring, and quarterly compliance reviews.
Which regulated industries does EPC Group serve with Purview?
EPC Group deploys Microsoft Purview for healthcare (HIPAA — Microsoft 365 BAA, PHI sensitivity labels, 7-year Audit Premium retention per 45 CFR §164.312), financial services (FINRA 4511 prompt logging, SEC 17a-4(f) tamper-evident retention, MNPI sensitivity labels), federal civilian and defense (FedRAMP High and CMMC 2.0 with GCC High deployment, IL4/IL5 boundaries, NIST 800-53 controls), pharma GxP (21 CFR Part 11 and FDA Annex 11), and EU operations (EU AI Act Annex III high-risk classification, GDPR Article 32 controls).
How does Purview integrate with Microsoft 365 Copilot governance?
Microsoft Purview is the foundational data layer that makes Copilot deployment safe in regulated industries. EPC Group's Copilot readiness work always starts with Purview because sensitivity labels, audit logging, and DLP policies must be deployed BEFORE Copilot grounding is enabled at scale. The integration covers: pre-Copilot data classification audit, sensitivity label deployment, oversharing control configuration, Audit Premium activation, Communication Compliance for prompt monitoring, and Insider Risk Management for AI-related anomaly detection.
What is the difference between Microsoft Purview and Data Loss Prevention (DLP)?
Microsoft Purview is the umbrella platform; DLP is one capability within Purview. Purview also includes sensitivity labels, audit, eDiscovery, retention policies, Insider Risk Management, Communication Compliance, and Compliance Manager. EPC Group typically deploys all eight capabilities together — DLP alone catches policy violations after the fact; the full Purview stack prevents violations proactively via auto-classification, applies retention to satisfy regulatory recordkeeping, surfaces insider risk patterns, and provides audit evidence for compliance attestations.
What Is Microsoft Purview Consulting?
Microsoft Purview is Microsoft's unified data governance and compliance platform. It consolidates eight capabilities — sensitivity labels, Data Loss Prevention, audit, eDiscovery, retention, Insider Risk Management, Communication Compliance, and Compliance Manager — under one administrative surface that spans Microsoft 365, Azure, and Microsoft Copilot.
EPC Group deploys all eight capabilities across regulated environments. The starting point is always a Microsoft Purview Readiness Assessment — a 4-6 week engagement that maps your current data classification posture, identifies sensitivity-label gaps, evaluates Copilot oversharing risk, and produces a deployment roadmap aligned to your regulatory framework.
