Microsoft 365 Copilot Governance Policy Library
Seven policies every enterprise Copilot deployment needs. Missing any one creates a gap the next audit or incident will find. This is the EPC Group library, delivered as ready-to-adopt templates plus tenant configuration.
The 7 policies
- Sensitivity Label Taxonomy — 4-6 label structure applied to content.
- DLP for Copilot Policy — what content Copilot cannot summarize based on labels.
- Copilot Acceptable Use Policy — what employees can and cannot ask, human review, PII handling.
- Prompt + Response Logging Retention Policy — retention duration, access controls.
- Copilot Incident Response Runbook — procedure when oversharing or misuse is discovered.
- Copilot Vendor Risk Policy — evaluation of Copilot Studio agents built by third parties or citizen developers.
- Workforce Training + Certification Policy — required training before license activation.
Frequently Asked Questions
What policies belong in a Microsoft 365 Copilot governance library?
Seven policies as baseline: (1) Sensitivity Label Taxonomy — the 4-6 label structure applied to content. (2) DLP for Copilot Policy — what content Copilot cannot summarize based on labels. (3) Copilot Acceptable Use Policy — what employees can and cannot ask Copilot to do, how to handle Copilot output before using it in business decisions. (4) Prompt + Response Logging Retention Policy — how long Copilot audit logs are retained, who can access them. (5) Copilot Incident Response Runbook — the procedure when oversharing or other misuse is discovered. (6) Copilot Vendor Risk Policy — how to evaluate Copilot Studio agents built by third parties or business-unit citizen developers. (7) Workforce Training + Certification Policy — what training every Copilot-licensed user must complete before license activation.
What is the standard sensitivity label taxonomy?
A 5-tier taxonomy EPC Group deploys as baseline: (1) Public — external marketing, patient education, published research. (2) General — internal non-sensitive. (3) Confidential — Finance — payroll, contracts, invoices, bank statements. (4) Confidential — Legal — contracts, litigation, IP. (5) Highly Confidential — variants for M&A / HR / PHI / customer PII depending on industry. Auto-labeling policies applied via Purview at the content type + keyword + trainable classifier level. DLP for Copilot enforces label-based blocking on tiers 3-5.
What does an acceptable use policy for Copilot look like?
Six core provisions. (1) Use Copilot as an assistant, not an authority — human review before acting on Copilot output. (2) Do not paste customer PII, employee PII, source code, or trade secrets into external AI tools (ChatGPT, Claude, Gemini) — use Microsoft 365 Copilot with tenant-grounded data instead. (3) Do not use Copilot to generate content that impersonates a person or organization. (4) Verify factual claims Copilot generates before using them in customer-facing or regulatory content. (5) Report suspected oversharing or misuse to the AI CoE within 24 hours. (6) Complete required Copilot training before receiving license activation. EPC Group ships a Copilot AUP template that maps to these six provisions plus industry-specific overlays.
How long should Copilot prompt + response logs be retained?
Minimum 1 year for standard enterprise deployments. 3 years for regulated organizations (HIPAA, GLBA, FINRA, SOC 2). 7 years for organizations with active or historic eDiscovery holds. Microsoft's Purview eDiscovery Premium tier is required for effective long-term retention and legal-hold-driven search across Copilot conversations. Access to Copilot logs is restricted to Security + Legal + CISO/DPO — regular managers do NOT have read access to individual employees' Copilot histories.
How does EPC Group deliver the governance library?
As a fixed-fee 3-week engagement (bundled into the 30-Day Copilot Readiness Accelerator or purchased separately). Deliverables: (1) All 7 policies as customized Word / Confluence documents adopted to the customer voice + industry vertical. (2) Purview sensitivity label taxonomy deployed in tenant. (3) DLP for Copilot policies deployed and validated. (4) Training curriculum outline with LMS-ready SCORM package. (5) Incident response runbook with named EPC Group escalation contact for the first 90 days post-adoption. (6) Board / audit presentation-ready summary deck.
