EPC Group Introduces Copilot and Microsoft 365 Tenant Security Review

EPC Group Introduces Copilot and Microsoft 365 Tenant Security Review

HOUSTON, TX -- April 25, 2026. EPC Group today introduced the Microsoft Copilot and Microsoft 365 Tenant Security Review, a fixed-fee assessment scoped specifically for organizations evaluating or expanding Microsoft 365 Copilot enablement.

Across EPC Group field engagements, the majority of Microsoft 365 tenants assessed for Copilot readiness exhibit at least one configuration gap that, left unaddressed, would expose sensitive content through Copilot prompts. The Review identifies and prioritizes those gaps before user enablement.

What the Review covers

1. Tenant-wide oversharing scan -- SharePoint Online, OneDrive, and Microsoft Teams permission audit
2. Conditional Access audit -- policy review for Copilot traffic, sign-in risk policies, and device compliance enforcement
3. Microsoft Purview sensitivity-label coverage -- label taxonomy review and auto-labeling rule coverage
4. DLP policy review -- Data Loss Prevention rules covering Copilot prompts and responses
5. Microsoft Purview Audit retention validation -- Audit Premium retention, eDiscovery readiness, Communication Compliance baseline
6. Written remediation roadmap -- prioritized findings, estimated effort, and sequencing plan

How it pairs with the 30-Day Accelerator

The Tenant Security Review is the precondition for the 30-Day Copilot, Purview and M365 Tenant Hardening Accelerator.
