EPC Group — historically the oldest continuous Microsoft Gold Partner in North America from 2016 until the program's retirement, a five-time G2 Leader in Business Intelligence Consulting, and the firm behind 10,000+ Microsoft implementations — today launched the 30-Day Copilot, Purview & Microsoft 365 Tenant Hardening Accelerator, a fixed-fee, end-to-end program that hardens a Microsoft 365 tenant and deploys Microsoft 365 Copilot to up to 5,000 users in 30 calendar days, with full Microsoft Purview sensitivity labeling, Data Loss Prevention coverage, oversharing remediation, Conditional Access governance, and a structured adoption and change management program in place before the first user prompt.
“Every CIO I talk to is in the same trap. They bought Copilot licenses six months ago, their CFO is asking why they aren't delivering value, and their CISO won't let them turn it on because Purview isn't tuned and SharePoint is overshared. We built the Accelerator to break that trap. Thirty days. Fixed fee. Governance-first. Up to five thousand users in production with sensitivity labels, DLP, oversharing remediation, Conditional Access, and a real adoption and change management program in place before anyone types a prompt.”
The Accelerator was built in response to a pattern EPC Group has observed across more than 240 Microsoft 365 readiness assessments since August 2025: enterprise and mid-market organizations are paying for Microsoft 365 Copilot licenses they cannot turn on safely. Security and compliance teams correctly insist Microsoft Purview must be tuned, oversharing must be remediated, and Conditional Access must be configured first — and the typical six-to-nine-month implementation timeline has become the operating bottleneck preventing Copilot from delivering the productivity value the organization is already paying for.
The 30-Day Timeline
Four weeks. Fixed scope. Senior architect on the engagement.
Week 1 — Discovery and Tenant Hardening
Comprehensive Microsoft 365 tenant audit, oversharing scan across SharePoint Online, OneDrive, and Microsoft Teams, sensitivity label taxonomy design, Restricted SharePoint Search enablement, and Conditional Access policy authoring for Copilot traffic. Senior architect kickoff with the client's CIO, CISO, and Chief Data Officer.
Week 2 — Microsoft Purview Configuration
Sensitivity label deployment with auto-labeling rules, DLP policy authoring for Copilot prompts and responses, DSPM for AI activation, eDiscovery readiness validation, and Communication Compliance baseline policies.
Week 3 — Oversharing Remediation
Top-50 SharePoint site permissions remediation, “Everyone except external users” link cleanup, broken inheritance correction, Microsoft 365 Group membership review, and Power BI workspace certification gating for sensitive datasets.
Week 4 — Pilot Rollout, Adoption & Change Management
Microsoft 365 Copilot enablement for the first 100 to 500 user cohort, Copilot agent inventory and governance, executive sponsorship alignment, Copilot Champion Network activation, role-based use-case training across Sales, Finance, Operations, HR, and IT, written prompt-engineering guides, and 30-day adoption measurement. Handoff to internal IT or to EPC Group's Managed Microsoft Cloud & Analytics Service for ongoing operational ownership.
Pricing & Scope
From $35,000 fixed fee
for organizations up to 5,000 users
- 30 calendar days from kickoff to first-user enablement
- Adoption and change management program included in base fee
- Bundles tenant hardening, Purview configuration, Copilot rollout, and adoption into one coordinated engagement
- Eligible for Microsoft ECIF and Copilot Acceleration Program funding in qualifying scenarios
- Remote-first delivery across the United States and Canada
Governance-First Is Non-Negotiable
The Accelerator is not a “turn Copilot on fast” offering. It is a “turn Copilot on safely in 30 days” offering. Every engagement includes the full Microsoft Purview hardening sequence as a prerequisite to user enablement.
The Varonis “Reprompt” attack disclosed in January 2026 demonstrated that a single malicious prompt can drain a misconfigured tenant in seconds — underscoring why governance must precede rollout, particularly in regulated industries where ungoverned AI is an unacceptable risk.
Adoption & Change Management Is the Differentiator
Most Microsoft Copilot deployments stall not at the technical rollout but at user adoption. EPC Group's field data across 240+ Microsoft 365 readiness assessments shows organizations enabling Copilot without a structured adoption and change management program typically reach 15 to 25 percent active usage in the first 60 days. Organizations with a structured adoption and change management program reach 65 to 80 percent active usage in the same window.
The Accelerator's Week 4 program is built around four operational deliverables:
- Executive sponsorship alignment with named departmental champions
- A Copilot Champion Network of one trained champion per fifty users
- Role-based use-case training covering Sales, Finance, Operations, HR, and IT scenarios
- Written prompt-engineering guides specific to the client's data and workflows
Active usage is measured at day 30 and reported in the final readout.
Anchored by the vCAIO Practice & Engagement Charter
Every Accelerator engagement is supervised by a senior consultant from EPC Group's Virtual Chief AI Officer (vCAIO) practice — the industry's first fractional AI executive service. Clients seeking ongoing AI executive oversight after the engagement can transition to the vCAIO Fractional Retainer at $6,500 per month or to the full Managed Microsoft Cloud & Analytics Service.
The Accelerator is delivered under EPC Group's published Engagement Excellence Charter: one named accountable program manager, four-hour first-response SLA, senior architects only with no junior consultant tier, and weekly written status reporting.
Who the Accelerator Is For
- Enterprise and mid-market organizations of 100 to 5,000 users running Microsoft 365 E3 or E5 with Copilot licenses purchased or planned
- CIOs whose Copilot rollout has been blocked by Purview gaps, oversharing concerns, or weak adoption planning
- CISOs who require governance before deployment as a non-negotiable condition of Copilot enablement
- Regulated industries — financial services, healthcare, government, energy, manufacturing — where ungoverned AI is unacceptable risk

Frequently Asked Questions
What does the 30-Day Copilot Tenant Hardening Accelerator include?
A fixed-fee, end-to-end engagement that hardens a Microsoft 365 tenant and deploys Microsoft 365 Copilot to up to 5,000 users in 30 calendar days. The base scope covers Microsoft Purview sensitivity labeling, Data Loss Prevention (DLP), oversharing remediation across SharePoint Online and OneDrive, Conditional Access policy authoring for Copilot traffic, executive sponsorship alignment, a Copilot Champion Network at one champion per 50 users, role-based use-case training, and written prompt-engineering guides. A senior architect from EPC Group's vCAIO practice supervises the entire engagement.
Why does it have to be governance-first instead of just turning Copilot on?
The January 2026 Varonis "Reprompt" disclosure demonstrated that a single malicious prompt can drain a misconfigured Microsoft 365 tenant in seconds. Microsoft 365 Copilot inherits whatever permissions the user has — if SharePoint is overshared with "Everyone except external users" links, if Purview sensitivity labels are not deployed, or if Conditional Access is not enforced, Copilot will surface that exposure at machine speed. Every engagement under this Accelerator includes the full Microsoft Purview hardening sequence as a prerequisite to user enablement. Governance is not an upgrade tier; it is the prerequisite.
How much does the Accelerator cost?
The Accelerator starts at $35,000 fixed fee for organizations up to 5,000 users. The base fee includes tenant hardening, Microsoft Purview configuration, oversharing remediation, Copilot pilot enablement, the adoption and change management program, and a senior vCAIO architect on the engagement. Custom scope, large tenant sizes (over 5,000 users), or complex regulatory environments (HIPAA, FINRA, SOC 2, CMMC, FedRAMP) may quote higher. The engagement is eligible for Microsoft ECIF and Copilot Acceleration Program funding in qualifying scenarios.
Can the Accelerator actually deliver in 30 calendar days?
Yes — for organizations up to 5,000 users with Microsoft 365 E3 or E5 already deployed, Copilot licenses purchased or planned, and a willing executive sponsor. The 30-day timeline assumes the four-week cadence in the published scope: Week 1 discovery and tenant hardening, Week 2 Purview configuration, Week 3 oversharing remediation, Week 4 pilot rollout and adoption. Organizations with extensive technical debt, fragmented identity environments, or unresolved compliance audits typically require a Phase 0 readiness assessment (4-6 weeks) before the 30-day clock starts.
What happens after the 30 days?
Two transition options. (1) Handoff to internal IT — EPC Group hands over runbooks, governance documentation, adoption metrics, and a 30-day post-engagement support window for triage. (2) Transition to EPC Group's Managed Microsoft Cloud & Analytics Service or the vCAIO Fractional Retainer ($6,500 per month) for ongoing operational ownership, monthly governance reviews, and executive AI advisory. Most regulated-industry clients choose option 2 because Microsoft Purview, Conditional Access, and Copilot agent inventory require active operational discipline after launch.
How does the Accelerator handle adoption — is this just a technical deployment?
Adoption is the differentiator and the entire Week 4 program. EPC Group's field data across 240+ Microsoft 365 readiness assessments shows organizations enabling Copilot without a structured adoption program reach 15-25% active usage in 60 days. Organizations with a structured program reach 65-80% in the same window. The Accelerator includes four operational deliverables: executive sponsorship alignment with named departmental champions, a Copilot Champion Network of one trained champion per 50 users, role-based use-case training across Sales / Finance / Operations / HR / IT scenarios, and written prompt-engineering guides specific to the client's data. Active usage is measured at day 30 and reported in the final readout.
Is this offering available for regulated industries?
Yes — financial services (SOC 2, FINRA, SEC 17a-4), healthcare (HIPAA, 21 CFR Part 11), government and defense contractors (FedRAMP, CMMC Level 2/3, ITAR), energy, and manufacturing. The Accelerator scope already includes the Purview Audit Premium retention setting, DSPM for AI activation, Communication Compliance baseline policies, and DLP rules that map to common regulatory frameworks. Industry-specific scope customization happens during the Week 1 discovery readout.
Why is EPC Group the right partner for this?
