Our credibility on Microsoft 365 is documented in Microsoft Press, in 11,000+ engagements, in 216+ M&A tenant migrations, and in 70+ Fortune 500 references. 216+ M&A tenant migrations — 1.83M users moved EPC Group completed 216+ Microsoft 365 tenant-to-tenant consolidations between 2023 and 2025 across private-equity portfolio companies, strategic-acquirer integrations, and divestitures — moving 1.83 million users in the process.

Compliance-native Microsoft 365 delivery across healthcare, financial services, federal, defense, manufacturing, energy, life sciences, legal, and higher-education industries. Senior-only delivery — no juniors on client engagements Every EPC Group Microsoft 365 engagement is delivered by senior architects with a minimum of 29 years of Microsoft experience. We do not staff associates, junior consultants, or offshore delivery teams onto client work. Fixed-fee accelerators with predictable scope, not open-ended time-and-materials. Industry-specific Microsoft 365 expertise Microsoft 365 controls, retention, sharing, audit posture, and Copilot governance are dictated by industry regulation — and the gap between a generic Microsoft 365 deployment and a compliant one is where most consultancies fail. EPC Group's industry practices each carry their own regulatory mapping and audit-tested evidence packages. HIPAA-compliant Teams + SharePoint + Copilot Microsoft 365 configured for protected health information (PHI) with the Microsoft HIPAA Business Associate Agreement, PHI sensitivity labels, DLP policies that block external PHI sharing, Communication Compliance for clinical Teams channels, Purview audit logging with 7-year retention, and Copilot governance that prevents PHI exposure through Copilot summaries. We serve hospital systems, health plans, life-sciences manufacturers, and clinical research organizations including Palmetto Infusion. Financial Services FINRA-compliant communication + records management Microsoft 365 for broker-dealers, investment advisers, banks, and credit unions — FINRA Rule 4511 retention, SEC Rule 17a-4 non-rewritable / non-erasable (WORM) storage on SharePoint Online with Purview retention labels, MNPI controls, Communication Compliance for trading floors and wealth advisors, OCC heightened standards, and FFIEC IT examination evidence packages.

FedRAMP Moderate and High baselines, CMMC 2.0 Level 2 and Level 3, NIST SP 800-171, ITAR, and CUI controls. Teams for shop-floor + Copilot for engineering Microsoft 365 for discrete and process manufacturers — Teams for shop-floor with F1 / F3 frontline licensing, Teams on shared kiosks and ruggedized devices, SharePoint engineering document control with ECN / ECO workflows, supplier-collaboration sites with conditional sharing, IATF 16949 and ISO 9001 audit evidence, and Copilot for engineering grounded in PLM (Siemens Teamcenter, PTC Windchill, Aras Innovator).

Matter management + secure external sharing Microsoft 365 for AmLaw firms and corporate legal departments — matter-centric SharePoint site provisioning, ethical-wall configuration, document classification with Microsoft Purview, eDiscovery (Premium) workflows, secure external client and counsel sharing via SharePoint Online sharing controls, and integration with iManage, NetDocuments, and HighQ as needed during transition. Higher Education Campus M365 + Teams for classrooms Microsoft 365 for universities and community college systems — A1 / A3 / A5 licensing strategy, FERPA-compliant document handling, Teams for Education with class teams, assignments, and Reading Coach, departmental hub-and-spoke SharePoint, identity federation with Shibboleth or Okta, accessibility (WCAG 2.2 AA, Section 508) review, and research-collaboration patterns for federally funded research.

We say where each firm legitimately wins; buyers detect shilling. EPC Group — where they legitimately win Senior-architect-led, fixed-fee, onshore-only delivery. Deepest M&A tenant-consolidation practice in the U.S. Founder is original SharePoint Beta Team member and since 2002-2003.

Each is sized to a buyer profile and a budget envelope. We provide transparent fixed-fee pricing after a one-hour scoping call with a senior architect — not after a multi-stage discovery and SOW negotiation cycle. M365 Health Check Fixed-fee assessment A two-week fixed-fee assessment of your Microsoft 365 estate — tenant configuration, identity and Conditional Access posture, SharePoint and Teams governance, security and compliance, oversharing exposure, Copilot readiness, and license optimization. Delivered as a costed roadmap with prioritized remediation backlog and a senior-architect readout. Best for: Organizations inheriting a Microsoft 365 estate from an acquisition, a prior consultant, or internal IT turnover — and CIOs and CISOs who need an objective second opinion before signing the next migration, Copilot, or governance SOW. Tenant configuration audit and drift report Identity, Conditional Access, and security posture review SharePoint, Teams, and OneDrive governance assessment Copilot readiness scorecard and oversharing exposure quantification License optimization model (E3 / E5 / F1 / F3 / Copilot) Prioritized remediation backlog with effort estimates and senior-architect roadmap readout M365 Migration Accelerator Fixed-fee migration A 90-day fixed-fee migration program — Google Workspace to Microsoft 365, Exchange Server 2010-2019 to Exchange Online, Notes / Domino to Microsoft 365, or tenant-to-tenant for M&A and divestitures. Includes discovery, design, pilot, wave rollout, and post-migration stabilization. Mailbox dependency graph prevents broken delegations and shared mailbox routing. Best for: Organizations moving from Google Workspace, Exchange on-premises, or a divested tenant to Microsoft 365 inside a single quarter — or consolidating multiple Microsoft 365 tenants after an M&A transaction. Discovery, gap analysis, risk register, and target architecture Migration plan with rollback playbook and dependency graph Pilot wave with 25-100 users in a real business unit Wave rollout in 500-2,500 user increments with daily cutover reporting Hypercare during every cutover and post-migration 30-day stabilization M365 + Copilot Adoption Program Multi-phase fixed-fee A four-to-six-month Copilot rollout program — Copilot Readiness Assessment, oversharing remediation, Purview label and DLP rollout, phased Copilot pilot, scale, adoption engineering, and ROI measurement. Delivered under the Governed AI on Microsoft Framework so Copilot stays inside the regulatory and ethical lines after go-live. Best for: Enterprises ready to deploy Microsoft 365 Copilot at scale but unwilling to expose PHI, PII, MNPI, or CUI through Copilot summaries. Includes regulated industries that need Restricted SharePoint Search (RSS) and Restricted Content Discovery (RCD) before any Copilot license is provisioned. Copilot Readiness Assessment with oversharing exposure quantification Purview sensitivity-label rollout and DLP policy tuning Restricted SharePoint Search (RSS) and Restricted Content Discovery (RCD) deployment Phased Copilot pilot, scale, and rollout with adoption engineering Champions network, role-based training, and ROI measurement against baseline Governed AI on Microsoft Framework operating model for post-go-live governance 24/7 Co-Managed M365 Services Monthly retainer (24/7) A senior-architect-led monthly retainer covering 24/7 incident response, Microsoft release-wave change management, quarterly governance reviews, monthly license true-up, security monitoring, and continuous Defender / Purview feature adoption.

EPC Group has delivered Microsoft 365 consulting since the launch of Office 365 in 2011 and is a 29-year Microsoft Solutions Partner with all six current designations. Our practice covers tenant architecture and multi-geo deployment, SharePoint Online modernization, Microsoft Teams platform engineering, Viva employee experience, Microsoft 365 Copilot rollout, Microsoft Purview data and AI governance, and 24/7 co-managed Microsoft 365 services.
