Generative AI Governance: Enterprise Framework

Generative AI Governance: Enterprise Framework (2026)

Generative AI governance in 2026 is the operating discipline ensuring Microsoft 365 Copilot, Microsoft Power BI Copilot, Microsoft Copilot Studio agents, GitHub Copilot Enterprise, Azure OpenAI deployments, and shadow AI tools meet board-level oversight, regulatory compliance (HIPAA, FINRA, SEC, EU AI Act, NIST AI RMF, ISO 42001), and enterprise risk management requirements.

EPC Group has delivered generative AI governance frameworks for Fortune 500 organizations since the Microsoft 365 Copilot early adopter program (2023).

TL;DR — Generative AI Governance 8-Pillar Framework

3. Sensitivity gating	Microsoft Purview labels (5-tier with industry sub-tiers)
4. Acceptable use	Microsoft Entra Conditional Access + DLP
5. Audit retention	Microsoft Purview Audit (Premium)
6. Compliance attestation	Microsoft Compliance Manager industry frameworks
7. Incident response	Microsoft Sentinel SOAR playbooks
8. Shadow AI detection	Microsoft Defender for Cloud Apps
