A single named methodology connecting Microsoft Purview, Fabric, Power BI, Microsoft 365, Entra ID, and Copilot — purpose-built for regulated enterprises.
By Errin O'Connor, Founder & Chief AI Architect, EPC Group
The Governed AI on Microsoft Framework is EPC Group's named seven-layer methodology that connects Microsoft Purview, Microsoft Fabric, Power BI, Microsoft 365, Microsoft Entra ID, and Microsoft Copilot into one coherent operating model. Designed for regulated industries — healthcare HIPAA, financial services FINRA and SEC, federal FedRAMP and CMMC, life sciences GxP, and EU AI Act — it covers identity, data, model, prompt, output, audit, and continuous improvement under a single governance plane.
Microsoft’s AI surface is expanding faster than most internal governance functions can absorb. Microsoft 365 Copilot, Microsoft Fabric Copilot, Power BI Copilot, Microsoft Security Copilot, and Microsoft Copilot Studio each introduce their own grounding paths, prompt logs, and admin surfaces. Treating each as a separate governance project produces seven disconnected configurations and seven separate audit narratives.
The Governed AI on Microsoft Framework addresses several key areas as a unified design problem. These areas include:
This approach ensures that the engineering and audit narrative align from Day 1 of the engagement. This alignment is essential for making Copilot deployable in regulated industries.
It also helps in passing the first audit cycle after go-live.
EPC Group has deployed this stack across hundreds of regulated tenants since the Microsoft Information Protection era (2017). The framework is the codification of that delivery experience — not a generic methodology drawn from a whitepaper.
Each layer maps to specific Microsoft products and to specific regulatory controls. Customers can present a single attestable evidence trail.
Conditional Access policies that gate Copilot, Fabric, and Power BI usage by user risk, device compliance, location, and regulatory boundary. Identity Governance access reviews on regulated security groups. Privileged Identity Management for Copilot admin roles.
Sensitivity label taxonomy (Public, Internal, Confidential, Highly Confidential, Regulated) with auto-classification rules. Container labels on SharePoint sites and Microsoft 365 Groups. Coverage target 80 percent on regulated content within 90 days.
Governed semantic models with row-level security, object-level security, dataset endorsement, and certified data sources. Microsoft Fabric capacity assignment by data domain and regulatory tier. OneLake shortcuts that inherit Purview labels.
Model registration in Azure AI Foundry with the assigned regulatory tier (commercial, HIPAA-eligible, FedRAMP, CMMC). Per-model evaluation, content-safety policy assignment, and indemnification status documented before any model reaches a production prompt path.
Microsoft Purview AI Hub for Copilot prompt and response capture. Data Loss Prevention policies that enforce sensitivity-label boundaries at Copilot grounding time. Prompt injection and obfuscation detection. Regulated-tier content blocked from grounding regardless of nominal user permission.
Audit Premium activated with 7 to 10 year retention per industry (HIPAA 7, FINRA 7, SEC 17a-4(f) 6 to 10, FedRAMP 7). Retention labels on every regulated content type. eDiscovery Premium enabled with legal hold workflow tested at deployment.
Microsoft Sentinel detection-engineering rules for AI anomalies (bulk Copilot prompt patterns, cross-boundary grounding attempts, sensitivity-label downgrade attempts). Compliance Manager scoring against the customer's regulatory framework. Quarterly attestation review with the customer's CISO, CIO, or Chief Compliance Officer.
Every regulated industry brings its own mapping between Microsoft governance products and statutory controls. EPC Group has shipped Governed AI engagements across each of the following.
PHI sensitivity-label deployment, Audit Premium 7-year retention, BAA-verified Microsoft 365 / Azure tenant configuration. Microsoft Restricted Search for Copilot grounding scoped to allowlisted clinical and administrative sites. Insider Risk Management tuned to PHI-handling personas.
FINRA Rule 4511 prompt logging via Communication Compliance. SEC Rule 17a-4(f) tamper-evident retention via Audit Premium. MNPI sensitivity labels with Information Barriers between research and investment banking. AI Hub monitoring for material non-public information leakage.
Microsoft 365 GCC or GCC High deployment with FedRAMP High authorization boundary. CMMC 2.0 Level 2 / Level 3 alignment with NIST 800-171 control mapping. IL4 / IL5 boundary enforcement for defense contractors. CUI sensitivity labels with banner-marking integration.
21 CFR Part 11 and FDA Annex 11 alignment. Validated AI workloads with change-control records. GxP retention policy on clinical-trial, regulatory-submission, and pharmacovigilance content. Audit Premium 7-plus year retention tied to regulatory clock for clinical phase.
Three tiers covering mid-market through Fortune 500. Every engagement starts with a fixed-fee Readiness Assessment.
$150,000 fixed-fee
12 weeks
Microsoft 365 E5 tenants with under 5,000 users, single-region, single regulatory baseline.
$350,000-$600,000
18-26 weeks
Multi-business-unit Fortune 1000 tenants, often with one regulated subsidiary (healthcare, financial services, or federal).
$800,000-$2,000,000
9-15 months
Fortune 500 with multiple regulated subsidiaries, international footprint, or aggressive Copilot Studio + Azure AI Foundry build-out.
Tier selection occurs during the fixed-fee Readiness Assessment, which costs between $25,000 and $75,000 and lasts 4 to 6 weeks. The following factors help determine the right entry point:
EPC Group measures and reports on quantified outcomes at engagement close — not just architecture diagrams. Engagement Excellence Charter applies.
Five patterns EPC Group sees repeatedly in self-built or partner-built deployments. The framework is designed to avoid each.
The single most common pattern. Copilot is licensed and broadly assigned without sensitivity-label coverage or AI Hub monitoring. Within 30-60 days the first compliance finding lands. Fix: AI Hub activated Day 1, sensitivity-label coverage at 80 percent on regulated content before broad Copilot license assignment.
Auto-classification rules deployed straight to enforcement; over-labeling generates user complaints; the policy gets rolled back; regulated content stays un-labeled. Fix: 30-day simulation mode for every auto-labeling rule, with the auto-applied label compared against human-applied where present.
Audit logs retained for 7 years, but DLP is not actually blocking Regulated-tier content in prompts. Audit shows the violations after the fact instead of preventing them. Fix: pair Audit Premium retention with DLP enforcement, not as alternatives.
Entra ID Conditional Access is configured for app sign-in but not extended to Copilot, Fabric capacity access, or Power BI sensitivity-label-protected datasets. Fix: explicit Conditional Access policies for the AI surface, tested at deployment.
Governance configured once, never reviewed. Within 6 months drift erodes the posture. Fix: quarterly Compliance Manager attestation review with the customer's Chief Compliance Officer or equivalent named as the accountable owner.
It is EPC Group's named seven-layer methodology that connects Microsoft Purview, Microsoft Fabric, Power BI, Microsoft 365, Microsoft Entra ID, and Microsoft Copilot into one coherent governance and operating model for regulated industries. Each layer maps to specific Microsoft products and to specific regulatory controls (HIPAA, FINRA, SEC, FedRAMP, CMMC, GxP, EU AI Act, GDPR), so a customer can present a single attestable evidence trail rather than ten disconnected configurations.
Because Microsoft's AI surface (Copilot, Fabric, Power BI Copilot, Microsoft Security Copilot, Microsoft 365 Copilot Studio) is expanding faster than most internal governance functions can absorb. A point project that deploys Purview today but does not address Entra ID conditional access, Audit Premium retention, and AI Hub monitoring will fail its next compliance audit. The framework treats the seven layers as a single design problem with explicit dependencies, so the engineering and the audit narrative are coherent from day one.
EPC Group standard timeline: Mid-Market Foundation (12 weeks, Microsoft 365 E5 tenants with under 5,000 users); Enterprise Build (18-26 weeks, multi-business-unit Fortune 1000 tenants); Complex Enterprise (9-15 months, Fortune 500 with multiple regulated subsidiaries or international footprint). Phase 1 always starts with a fixed-fee Readiness Assessment (4-6 weeks, scoped after discovery) so scope, regulatory baseline, and tier are confirmed before the full Statement of Work is signed.
Designed for healthcare (HIPAA covered entities and business associates with PHI in Microsoft 365 / SharePoint / Power BI), financial services (FINRA 4511 prompt logging, SEC 17a-4(f) tamper-evident retention, MNPI sensitivity labels, Communication Compliance), federal civilian and defense contractors (FedRAMP High and CMMC 2.0 Level 2 and 3, often on Microsoft 365 GCC or GCC High), life sciences (21 CFR Part 11, FDA Annex 11, GxP-validated AI workloads), and EU operations (EU AI Act Annex III high-risk classification, GDPR Article 32 controls).
A standard Copilot deployment configures licensing, enables Copilot in Word/Excel/PowerPoint/Outlook/Teams, and sets a handful of admin policies. The Governed AI on Microsoft Framework treats Copilot as one consumer of a governed data and identity plane — the work happens at the Entra ID conditional access layer, the Purview sensitivity label and DLP layer, the Audit Premium retention layer, the Communication Compliance prompt-supervision layer, and the Sentinel detection-engineering layer BEFORE any Copilot license is broadly assigned. The outcome is a Copilot rollout that survives a regulator audit, not one that creates the compliance findings.
Quarterly outcome metrics include: sensitivity-label coverage on regulated content (target 80 percent within 90 days), Copilot oversharing exposure rate (number of Copilot grounding events that would have surfaced Confidential or higher content without enforcement), Audit Premium retention attestation status (HIPAA, FINRA, SEC), Insider Risk Management alert closure rate and false-positive rate, Communication Compliance prompt-supervisory review volume, and quarterly compliance-incident rate. Year-over-year, customers typically see 60-80 percent reduction in audit findings tied to data classification gaps and a measurable reduction in time to respond to eDiscovery / regulator requests.
Every Governed AI on Microsoft engagement begins with the Readiness Assessment (a fixed fee scoped after discovery, over 4-6 weeks). The Assessment produces a baseline gap report, a tenant-specific Statement of Work, and a fixed-fee proposal for the next phase. Customers can choose to stop at the Assessment without further commitment. A named senior architect is assigned at kickoff and remains on the engagement through close — no rotating staff. Engagement Excellence Charter applies: four-hour first-response SLA, G2 verified reviews, one accountable program manager.
Senior architects (not sales) take discovery calls. Fixed-fee Readiness Assessment available before any larger commitment.
