Why Leading AI Governance Matters

Risk

Generic AI consulting leaves regulators dissatisfied. Leading AI governance leaves audit-defensible posture.

Cost

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

Time

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

Brand

Public AI incidents — sensitive data leakage, AI-generated harmful content, bias incidents — cause material brand damage. Leading AI governance prevents these incidents.

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, higher cost, and less Microsoft AI stack depth.

How is EPC Group different from boutique AI firms?

Most boutique AI firms have AI strategy + ethics expertise but lack Microsoft 365 Copilot + Microsoft Copilot Studio + Microsoft Purview + Microsoft Sentinel + Microsoft Compliance Manager hands-on implementation depth. EPC Group is industry-specialized AND Microsoft-deep.

How long does AI governance implementation take?

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

What about EU AI Act?

The EU AI Act applies to organizations with EU operations. EPC Group standard 12-week EU AI Act compliance accelerator: $400K-$800K.

Who delivers EPC Group AI governance engagements?

Errin O'Connor (Chief AI Architect, CEO, 4-time Microsoft Press author) leads. Senior AI governance architects with combined Microsoft Defender, Microsoft Purview, Microsoft Sentinel, Microsoft Entra, and industry-specific compliance experience.
