Enabling Epic MyChart Through Control-Plane Ownership
Executive Summary
Enabled Epic MyChart by reclaiming identity and DNS ownership in a 71-hospital Azure healthcare environment, without downtime or disruption to patient care.
This engagement transitioned a large healthcare provider from an MSP-managed identity and DNS model to an Azure-native, provider-owned control plane, meeting Epic's security and governance requirements while establishing a scalable foundation for future digital health initiatives.
Hospital Sites
Identities Migrated
DNS Zones
Downtime
The Challenge
Epic MyChart readiness was blocked by foundational infrastructure constraints:
- ✗Identity and DNS controlled by third parties
- ✗Limited auditability and change governance
- ✗Slow response to security and compliance requirements
Without direct ownership of the control plane, Epic deployment could not proceed.
The Solution
We transitioned the organization from an MSP-managed environment to an Azure-native identity and DNS architecture owned and operated by the provider.
The solution preserved federated authentication, eliminated opaque third-party dependencies, and delivered authoritative DNS and identity governance aligned with Epic's compliance standards—with zero downtime.
