CMMC and HIPAA Compliance with Intune and SharePoint for a Healthcare Organization

Healthcare professional using a secure device for CMMC and HIPAA compliance with Microsoft 365

Streamlined compliance, secure device management and audit ready external partnerships for regulated healthcare operations.

  • Industry: Healthcare services and compliance
  • Organization Size: 2,000+ employees
  • Users/Teams: Field Technicians, Quality Assurance, Operations
  • Endpoints in Scope: about 350 managed devices
  • Solution Type: CMMC readiness, endpoint modernization, compliant external collaboration
  • Tech Stack: Microsoft Intune, Windows Autopilot, Entra ID (Conditional Access, MFA), Microsoft Defender, Purview DLP, SharePoint Online, Power Automate

Overview

This healthcare compliance organization was relying on ad hoc external file sharing with partner labs and clinics, guest access created on demand without formal approval, and manual audit evidence collection. Facing federal compliance mandates, it needed to modernize endpoint provisioning, formalize external data sharing and fully evidence all collaboration for CMMC readiness, alongside HIPAA requirements.

ESW deployed Microsoft native device management as part of a broader Microsoft 365 consulting engagement, enabled secure external partnerships through SharePoint and automated workflows, delivered hands on training for healthcare teams, and strengthened telemetry and control around sensitive healthcare data.

Challenge

  • Device Inconsistency and Audit Risk: Varying provisioning standards exposed field devices essential for mobile technicians and QA to compliance failures, with inconsistent controls between sites.
  • Unstructured External Collaboration: Ad hoc external file sharing with partner labs and clinics was common practice, lacking standard approvals or audit trails and jeopardizing patient privacy and CMMC progress.
  • Manual, Untracked Approvals: Operations and QA teams routinely created guest access on demand, leaving gaps in evidence collection and formal authorization.
  • Legacy Security Practices: Email and security configurations left high risk legacy protocols enabled, and evidence collection for audits was manual and error prone.

Solution

1. Endpoint and Identity Modernization

  • Standardized Windows device imaging using Intune and Autopilot.
  • Implemented organization wide Conditional Access and MFA, aligned with HIPAA and CMMC requirements.
  • Defender for Endpoint and DLP (Purview) deployed to all field and QA devices.
  • Quarterly documented access reviews, with approvals centrally stored for audit readiness.

2. Secure External Collaboration Hub

3. Training and Enablement

  • Targeted training for site and external access procedures, customized for Operations managers, QA team leads and Field Tech coordinators.
  • End user training for front line staff: secure navigation, document handling, data privacy and compliant sharing practices.

4. Email and Security Posture

  • Disabled legacy email protocols (IMAP, POP, SMTP AUTH).
  • Extended quarantine retention, safer outbound policies and international spam controls.
  • Longer and more effective data retention for incident investigation.

5. Implementation and Change Adoption

  • 6 to 8 week delivery: rapid assessment, then pilot rollout, then organization wide launch.
  • Hypercare support through the first audit cycle after deployment.

Impact

  • Provisioning times cut by 50%: Healthcare field devices ready for use within 1 to 1.5 hours using standardized, compliant baselines.
  • Compliant Collaboration: All requests for external sharing (e.g., sending PHI to partner labs) are now routed, approved and logged, providing rapid, audit ready evidence.
  • Security and Consistency: 100% MFA adoption and policy enforcement for all field, QA and operations teams.
  • Practical Enablement: Step by step guides for site requests, guest management and secure collaboration, adapted for nontechnical users.
  • Reduced Audit Findings: Audit pack maintained in SharePoint; all prior findings related to device and data sharing now closed.
  • Lowered Security Risk: Legacy email exposure eliminated; faster incident investigation with policy and evidence enhancements.

Technology

  • Microsoft Intune, Windows Autopilot, Entra ID (Conditional Access, MFA)
  • Microsoft Defender for Endpoint and Defender for Office 365, Purview DLP
  • SharePoint Online, Power Automate, Microsoft Graph API
  • SharePoint audit and evidence repository; Power BI reporting as needed

Frequently Asked Questions

Can Microsoft 365 support CMMC readiness?

Yes. In this project, Intune, Windows Autopilot, Entra ID Conditional Access and MFA, Microsoft Defender and Purview DLP were aligned with HIPAA and CMMC requirements, and an audit pack is maintained in SharePoint. All prior findings related to device and data sharing are now closed.

How was external sharing with partner labs controlled?

All external site and guest requests go through a SharePoint Collaboration Request Hub. Power Automate flows handle approval and provisioning with full request and result audit logs, and guest invites run through Microsoft Graph for consistent identity and access tracking.

How long did the rollout take?

Delivery took 6 to 8 weeks: rapid assessment, then pilot rollout, then organization wide launch, with hypercare support through the first audit cycle after deployment.
