Healthcare Network Segmentation
Clinical system isolation using VLAN design, keeping EMR and patient data systems on a separate, documented network segment from general staff and guest traffic, with a written configuration record for DPA compliance.
Key highlights
- Dedicated clinical VLAN for EMR and patient-facing systems
- Documented network segmentation configuration for DPA audits
- TP-Link Omada managed switching for VLAN enforcement
- Guest and staff networks fully isolated from clinical systems
- Written segmentation report delivered on completion
Clinical systems need their own network segment
In a healthcare environment, the network carries two very different categories of traffic. Administrative systems, guest Wi-Fi, and general staff traffic that can tolerate the same security posture as any business environment. And clinical systems, EMR platforms, diagnostic equipment, patient monitoring, and pharmacy systems, that hold sensitive patient data and must be isolated from general traffic. Mixing these on a flat network creates both a security risk and a compliance gap.
Why clinical VLAN segmentation matters for DPA compliance
The Kenya Data Protection Act 2019 requires appropriate technical measures to protect sensitive personal data. Patient health records are classified as sensitive data. A documented network segmentation design, showing that clinical systems are isolated from general access, is a concrete technical safeguard that satisfies this requirement and can be produced during a compliance audit.
What the segmentation design covers
Clinical VLAN
EMR servers, diagnostic imaging systems, pharmacy software, and any networked medical device are placed on a dedicated VLAN. Traffic between the clinical VLAN and other network segments is restricted by firewall rules, not just physical separation.
Staff and admin VLAN
General business workstations, printers, and administrative systems sit on a separate VLAN with standard business internet access but no direct path to clinical systems.
Guest and visitor VLAN
Patient and visitor Wi-Fi is isolated from both clinical and administrative systems. Guest devices reach the internet and nothing else.
IoT and CCTV VLAN
IP cameras, access control readers, and building management devices are placed on a separate VLAN, preventing lateral movement to clinical or administrative systems.
Documented configuration report
The deliverable isn't just a configured network. It's a written configuration document that describes every VLAN, the systems assigned to it, the inter-VLAN routing rules enforced at the firewall, and the rationale for each design decision. This document supports DPA audits and provides a baseline for future network changes.
Book a healthcare network assessment
A network assessment scopes the existing environment and identifies what needs to change before clinical segmentation can be implemented. For facilities already using an EMR, the assessment can usually be completed in a half-day visit. Contact Sentire to schedule.
