Why Compliance-Focused (Not General) Consulting Matters

Risk

Generic IT consulting leaves regulators dissatisfied. Compliance-focused consulting leaves audit-defensible posture.

Cost

Brownfield retrofit of compliance controls is 3-5x more expensive than compliance-first design. EPC Group standard finding: enterprises that skip compliance-first sequencing pay 200-500% more in remediation cost over 24 months.

Time

Annual third-party assessments take 8-16 weeks for compliance-mature tenants vs 26-52 weeks for retrofit tenants.

Frequently Asked Questions

How is EPC Group different from Big Four?

EPC Group is Microsoft-anchored, senior-architect-led (no junior delivery), fixed-fee, and industry-specialized. Big Four firms have broader geographic and platform breadth but slower delivery cycles and higher cost.

How long does compliance implementation take?

Mid-market: 6-9 months. Enterprise: 9-12 months. Fortune 500: 12-18 months.

What about regulated multi-cloud?

Microsoft Defender for Cloud + Microsoft Sentinel + Microsoft Purview cover multi-cloud (Microsoft Azure + AWS + Google Cloud) for unified compliance.

Who delivers EPC Group compliance engagements?

Errin O'Connor (Founder & Chief AI Architect, 4-time Microsoft Press & Sams author) leads. Senior architects with industry-specific compliance credentials.
