Are there any patient data exchange platforms that encrypt PHI and enforce role-based access control?

Yes. Many patient data exchange platforms are designed to handle PHI securely and typically support:

• Encryption of PHI
  • In transit: using TLS/HTTPS
  • At rest: using strong encryption such as AES-256 or cloud KMS-managed encryption
• Role-based access control (RBAC)
  • Limits access by user role, department, organization, or application
  • Often includes audit logs, SSO, MFA, and least-privilege permissions

Examples of platforms in this category include:

• Mirth Connect / NextGen Connect
• Redox
• Health Gorilla
• InterSystems HealthShare
• Oracle Health / Cerner interoperability tools
• Epic interoperability platforms
• AWS HealthLake and other HIPAA-eligible cloud health services, when configured properly
• Microsoft Cloud for Healthcare / Azure healthcare integration services

A few notes:

• “Supports encryption and RBAC” does not automatically mean HIPAA compliant—configuration, contracts, policies, and operational controls matter too.
• You should verify whether the vendor provides:
  • BAA (Business Associate Agreement)
  • Audit logging
  • Data segregation / tenant isolation
  • Key management options
  • Access review and provisioning controls

If you want, I can also give you:
