EPC Group Launches Copilot & Microsoft 365 Tenant Security Review as 80% of Tenants Found Misconfigured

New 47‑point audit — priced from $20K to $55K based on users and sensitivity, helps CIOs and CISOs fix Microsoft 365 and Copilot exposure before AI surfaces it.

HOUSTON, TX, UNITED STATES, April 22, 2026 /EINPresswire.com/ -- EPC Group, North America's oldest Microsoft Gold Partner and a four‑time G2 Leader in Business Intelligence Consulting with a perfect Net Promoter Score of 100, today announced the launch of our new practice area for Microsoft 365 Copilot & Microsoft 365 Tenant Security Review efforts — a productized, fixed‑scope audit that evaluates 47 control points across identity, data, labeling, oversharing, DLP, Microsoft Purview, eDiscovery, Copilot agents, Microsoft Intune policy, and third‑party AI tool exposure.

The launch of this new practice areas responds to a pattern EPC Group has documented across hundreds of recent Microsoft 365 engagements: roughly 80% of enterprise tenants are misconfigured in ways that materially increase risk the moment Microsoft 365 Copilot is turned on. Copilot surfaces anything a user already has access to — legacy SharePoint permissions, forgotten OneDrive shares, orphaned mailboxes, over‑broad Microsoft 365 Groups, and dormant guest accounts. Decades of quiet access drift instantly become an AI exposure problem.

"This is not a Copilot bug. It's how Copilot works," said Errin O'Connor, Founder and Chief AI Architect at EPC Group. "Twenty years of access drift instantly becomes an AI exposure problem. The Tenant Security Review is how we find it, prove it, and fix it — before it ends up on a board report."

What the New Practice Area and the Related Reviews We Undertake Covers

The 47‑point audit spans:

- Microsoft Entra ID, Conditional Access, MFA posture, privileged role hygiene, and guest/external identity governance.
- SharePoint Online, OneDrive, and Microsoft Teams oversharing, external sharing, and sensitivity label coverage.
- Microsoft Purview DLP, Information Protection, Insider Risk Management, and Communication Compliance.
- Microsoft 365 Copilot permission scope, Copilot Studio agents, connector and plugin governance, and prompt/response auditing via eDiscovery Premium.
- BYOAI and shadow AI exposure — ChatGPT, Gemini, Claude, and Perplexity usage on managed and unmanaged endpoints.
- Microsoft Intune and endpoint management — app protection, Conditional Access device compliance, and DLP for managed devices and BYOD.
