Networking Services for Healthcare Organizations: Requirements and Providers
Healthcare networking operates under a distinct set of federal mandates and technical constraints that distinguish it from general enterprise networking. This page covers the regulatory framework governing healthcare network infrastructure, the core technical mechanisms that satisfy those requirements, practical deployment scenarios across care settings, and the decision boundaries that separate compliant from non-compliant architectures. Understanding these requirements is essential for any organization selecting or evaluating network compliance and regulatory requirements in a clinical context.
Definition and scope
Healthcare networking encompasses the design, implementation, and ongoing management of network infrastructure that transmits, stores, or provides access to protected health information (PHI) as defined under the Health Insurance Portability and Accountability Act of 1996. The HIPAA Security Rule (45 CFR Part 164, Subpart C) establishes the federal floor for technical safeguards applicable to electronic PHI (ePHI). Any network segment that carries ePHI — including imaging traffic, electronic health record (EHR) system data, telehealth sessions, and medical device telemetry — falls within scope.
The scope extends beyond acute-care hospitals. Physician practices, outpatient clinics, long-term care facilities, health plans, and healthcare clearinghouses are all covered entities under HIPAA. Business associates — including managed service providers and cloud networking vendors that handle ePHI on behalf of covered entities — must also execute a Business Associate Agreement and meet equivalent Security Rule requirements.
The scope of applicable standards is not limited to HIPAA. The Centers for Medicare and Medicaid Services (CMS) Conditions of Participation (42 CFR Part 482) impose operational requirements that carry network implications, including requirements for EHR interoperability. The NIST Cybersecurity Framework (NIST CSF 2.0) and NIST SP 800-66 Revision 2 provide implementation guidance mapped directly to HIPAA Security Rule controls.
How it works
A compliant healthcare network architecture is built around four functional layers that map to the HIPAA Security Rule's technical safeguard categories:
-
Access control layer — Role-based network segmentation ensures that only authorized devices and users reach ePHI systems. This typically involves VLAN segmentation separating clinical systems, administrative traffic, and guest or IoT device traffic. Network security services implement 802.1X port authentication to enforce device identity before granting network access.
-
Encryption and transmission security layer — The HIPAA Security Rule at 45 CFR §164.312(e)(2)(ii) specifies encryption of ePHI in transit as an addressable implementation specification. In practice, healthcare organizations deploy TLS 1.2 or TLS 1.3 for all ePHI-bearing application traffic, and IPsec or WireGuard tunnels across WAN segments. SD-WAN services configured with end-to-end encryption satisfy this layer while maintaining application-aware routing for clinical workloads.
-
Audit and monitoring layer — HIPAA §164.312(b) requires hardware, software, and procedural mechanisms to record and examine activity on systems containing ePHI. Network monitoring services in healthcare environments must generate tamper-evident logs with sufficient granularity to support breach investigations under the HIPAA Breach Notification Rule (45 CFR Part 164, Subpart D).
-
Availability and redundancy layer — The Security Rule's contingency planning standard (§164.308(a)(7)) requires organizations to maintain access to ePHI during emergencies. Network redundancy and failover services are not optional in clinical environments where system downtime directly affects patient care. Dual-carrier WAN configurations, automatic failover routing, and backup power for network hardware all feed into the contingency plan.
Common scenarios
Hospital campus networks — Acute care hospitals typically deploy a multi-tier architecture with a segmented core, distribution, and access layer. Medical devices — infusion pumps, patient monitors, imaging systems — occupy a dedicated IoT VLAN enforced by IoT networking services controls. Imaging traffic (DICOM) requires guaranteed bandwidth allocations because DICOM studies can exceed 1 GB per scan. Separation between clinical and operational technology (OT) networks is a baseline expectation under guidance from the HHS 405(d) Task Group's Health Industry Cybersecurity Practices (HICP).
Telehealth and remote care — The growth of CMS-reimbursed telehealth services following regulatory changes documented under the Consolidated Appropriations Act of 2023 created demand for encrypted, low-latency connectivity between patient-facing endpoints and provider systems. WAN services supporting telehealth must provide sufficient upstream bandwidth — typically 1.5 Mbps minimum per simultaneous HD video session — with Quality of Service (QoS) prioritization for real-time traffic.
Multi-site physician groups and clinic networks — A practice operating 10 or more locations requires consistent policy enforcement across all sites. Managed network services with centralized policy management reduce the per-site compliance burden by pushing uniform firewall rules, encryption policies, and access controls from a single management plane.
Rural and critical access hospitals — Facilities operating under the CMS Critical Access Hospital (CAH) designation (42 CFR Part 485, Subpart F) face the additional constraint of limited fiber infrastructure. Fiber optic networking services are expanding into rural markets, but hybrid WAN designs using 4G LTE or 5G fixed wireless as secondary paths remain common in areas where terrestrial fiber is unavailable.
Decision boundaries
The primary decision boundary in healthcare networking is the PHI/non-PHI traffic distinction. Network segments that never carry ePHI — public Wi-Fi for patients, administrative office printing — are not subject to the Security Rule's technical safeguard requirements, though they must still be segmented to prevent PHI ingress.
A secondary boundary separates covered entity infrastructure from business associate infrastructure. A cloud networking provider operating network-as-a-service must sign a Business Associate Agreement before managing any network segment that could carry ePHI. Network-as-a-Service (NaaS) vendors without executed BAAs represent a compliance gap regardless of their technical controls.
The third boundary concerns on-premises versus cloud-hosted clinical systems. Organizations migrating EHR workloads to cloud infrastructure must apply the Security Rule's encryption and access control requirements to the virtual network segments within the cloud environment, not only to physical on-premises infrastructure. Cloud networking services for healthcare must support private connectivity options — AWS PrivateLink, Azure Private Endpoint, or equivalent — to avoid routing ePHI over the public internet.
A fourth boundary governs wireless versus wired clinical networks. The NIST SP 800-153 guideline on wireless LAN security recommends against transmitting ePHI over open or WPA2-Personal wireless segments. Healthcare-grade wireless networking services deploy WPA3-Enterprise with 802.1X authentication and separate SSIDs for clinical and non-clinical traffic as the minimum acceptable configuration.
