What EPC Group Delivers with Gemini
EPC Group is a Microsoft Solutions Partner Founded in 1997 with a senior-architect AI consulting practice that has shipped Google Gemini implementations since the Gemini beta. The Gemini practice sits inside the broader AI consulting and AI governance offering, and is delivered alongside Microsoft 365 Copilot, Azure OpenAI, Anthropic Claude, and the Power Platform agent stack for enterprises that need defensible cross-vendor model selection.
Gemini Practice — Six Service Pillars
- Gemini integration with Google Cloud Vertex AI. Production deployment of Gemini Pro and Flash with VPC Service Controls, customer-managed encryption keys, and tenant-resident data residency.
- Microsoft-stack interoperability. Calling Gemini from Power Automate, Azure Functions, Logic Apps, SharePoint Framework solutions, and Teams custom apps — with Microsoft Entra identity, Purview labeling, and audit logging on every cross-cloud call.
- Multimodal workflows. Image and document classification, video analysis, audio transcription with speaker diarization, and combined text-image reasoning for clinical imaging review, contract diagram extraction, and engineering drawing review.
- Long-context document workloads. Gemini 1.5 Pro's 2M-token context window for whole-codebase review, multi-document policy analysis, and large-scale regulatory mapping.
- Workspace-to-Microsoft-365 migrations. When buyers consolidate off Google Workspace onto Microsoft 365, EPC Group manages the AI migration thread — extracting institutional patterns from Gemini usage, mapping to Microsoft 365 Copilot equivalents, and preserving audit trails through the tenant cutover.
- Safety, compliance, and governance. Vertex AI Safety Filters tuning, Purview-equivalent classification of prompts and responses, immutable audit logging, and the architecture artifacts buyers need for HIPAA, SOC 2, FINRA, FedRAMP-aligned, CMMC, and GxP reviews.
When Gemini vs. Microsoft 365 Copilot
- Multimodal reasoning across images, video, audio, and text in a single call.
- 2M-token context window — whole-codebase review, very large document corpora.
- Buyer-mandated cross-vendor model diversity for risk decomposition.
- Specific Google Workspace ecosystem integration during a migration phase.
Engagement Model
Gemini consulting engagements run on The EPC Group Lifecycle — Assess, Modernize, Govern, Operate, Enable — with fixed-fee accountability at every stage and the same senior architects accountable from costed roadmap through ongoing operations.
Frequently Asked Questions
EPC Group delivers Gemini integration with Google Cloud Vertex AI and Microsoft-stack interoperability — calling Gemini from Power Automate, Azure Functions, and custom agents — plus multimodal workflow design (text + image + audio + video), retrieval-augmented patterns, safety guardrails, audit logging, and the seven-layer agentic governance framework.
Gemini 2.0 Flash for low-latency multimodal classification and routing, Gemini 1.5 Pro for long-context document review and reasoning (up to 2M tokens), Gemini 1.5 Flash for high-throughput inference, and the underlying Google AI Studio + Vertex AI deployment patterns for tenant-resident workloads.
Microsoft 365 Copilot remains the productivity copilot anchored to Microsoft Graph, Purview labels, and tenant policy — the daily-driver for office workers. Gemini is engaged where the workload demands multimodal reasoning across image and video, very long context (up to 2M tokens), or buyer-mandated cross-vendor model diversity. EPC Group designs the routing layer that decides which model handles which class of request, with Purview classification and audit logging on every model call.
Google Cloud Vertex AI offers Gemini deployment with HIPAA BAA support, SOC 2 coverage, and FedRAMP-aligned posture for specific regions and contract structures. EPC Group designs the deployment posture — VPC-SC isolation, prompt logging policy, data-residency choices, and Purview-equivalent classification — and provides the architecture artifacts buyers need for security review.
Layer 1 Microsoft Entra non-human identity for any Gemini-backed agent calling downstream Microsoft Graph. Layer 2 Decision boundaries. Layer 3 Escalation rules. Layer 4 Audit trail on every prompt and response. Layer 5 Monitoring for anomaly detection. Layer 6 Named-owner accountability. Layer 7 Lifecycle controls including model-version pinning, canary, and rollback. The framework applies identically across Gemini, Microsoft 365 Copilot, Claude, and OpenAI agents.
EPC Group engaged with Google Gemini during the Gemini beta and has shipped Gemini-anchored solutions for regulated enterprises ever since. The firm's Gemini practice operates inside the broader AI consulting team led by Errin O'Connor and includes Google-Workspace-to-Microsoft-365 migration scenarios where the buyer is consolidating off the Google stack onto Microsoft.
