M365 Tenant Hardening Partner FAQ
Who should I hire for Microsoft 365 tenant hardening?
Match the partner to your project profile. (1) Small/mid-market with straightforward M365 workloads + internal IT capable — Microsoft FastTrack (free, included with E3/E5) covers 60-70% of hardening needs; internal team handles the rest. (2) Mid-market to enterprise in regulated industries (HIPAA, SOC 2, PCI) — hire a Microsoft Solutions Partner with Security + Modern Work designations. (3) Enterprise + complex environments + Copilot readiness + BYOAI concerns — hire a boutique Microsoft specialist like EPC Group with all six Solutions Partner designations + deep Purview + Entra + Copilot governance experience. (4) DoD contractors + ITAR + CMMC — hire a partner with GCC High deployment history + CMMC 2.0 assessor relationships.
What is Microsoft FastTrack and when is it enough?
Microsoft FastTrack is a free onboarding service Microsoft provides to customers with 150+ M365 licenses. It covers: (1) Tenant setup + baseline configuration. (2) Standard security best-practices enablement (Conditional Access baselines, MFA rollout, basic DLP). (3) Migration support for common workloads. (4) User adoption guidance. FastTrack is sufficient when: workloads are standard (Exchange + SharePoint + Teams + basic Copilot), compliance requirements are baseline (no HIPAA / FedRAMP / CMMC), internal IT is Purview-capable, and there is no active regulatory audit. FastTrack is NOT sufficient for: regulated industries, complex environments, Copilot governance depth, custom app inventory, BYOAI governance.
What is a Microsoft Solutions Partner?
Microsoft Solutions Partner is the current-tier Microsoft partner designation (replaced Gold Partner status in 2022). There are six Solutions Partner designations: (1) Data + AI (Azure), (2) Infrastructure (Azure), (3) Digital + App Innovation (Azure), (4) Business Applications, (5) Modern Work, (6) Security. Each requires: performance measures (revenue + growth), skilling (certifications), and customer success measures (deployment + usage). EPC Group holds all six Solutions Partner designations — one of the smaller number of partners with full portfolio depth. When hiring for M365 tenant hardening, minimum: Modern Work + Security designations.
Big Four vs Solutions Partner vs boutique specialist?
Match to project intent: (1) Big Four (Deloitte / PwC / EY / KPMG) — best for board-facing programs with multi-vendor (Microsoft + AWS + Salesforce) scope + brand credibility for audit committee. Cost: $400-$650/hr blended. Depth of Microsoft-only expertise: lighter. (2) Global system integrators (Accenture / Avanade / Slalom) — best for multi-year enterprise transformation programs with multi-region deployment. Cost: $300-$500/hr blended. Depth: broad but less specialist. (3) Boutique Microsoft specialists (EPC Group and similar) — best for depth-first engagements requiring senior consultants on the actual work + long-term partner tenure. Cost: $200-$375/hr blended. Depth: highest for Microsoft-only work.
What credentials should I verify?
Six credentials to verify before hiring: (1) Microsoft Solutions Partner designations (all six ideal; minimum Modern Work + Security for M365 hardening). (2) Individual senior consultant certifications (MCE, Certified Cybersecurity Architect, Purview + Compliance certifications). (3) Case studies matching your industry + size (ask for 3-5 specifically). (4) Reference calls with prior clients (2-3 minimum, direct conversations). (5) Bench continuity — will the pitch team do the actual work, or will juniors execute? (6) Author + speaker footprint — do their senior staff publish, present at Microsoft Build/Ignite, contribute to Microsoft engineering feedback? Depth signals matter.
What should a tenant-hardening engagement include?
Minimum scope for enterprise-grade tenant hardening: (1) Discovery + assessment (2-3 weeks) — 12-gap audit (permission drift, DLP coverage, sensitivity labels, Insider Risk, Entra Conditional Access, Defender integration, Compliance Manager). (2) Foundation deployment (4-8 weeks) — sensitivity label taxonomy, DLP baseline, permission cleanup, guest access restrictions, legacy auth removal. (3) Advanced controls (4-8 weeks) — Insider Risk, Communication Compliance, Purview eDiscovery Premium if needed. (4) Copilot readiness gap closure (2-4 weeks) — BYOAI policy, approved-tool list, endpoint DLP. (5) Handoff + ongoing governance (2 weeks) — runbook, monitoring, quarterly reviews. Full program: 14-25 weeks + $155K-$300K depending on scope.
