Clinical Network Isolation and Medical Device Protection

Healthcare networks connect life-critical medical devices, patient records, and clinical systems. When ransomware reaches a hospital network, it does not just encrypt data. It cancels surgeries, diverts ambulances, and puts lives at risk.

Back to Control
Control

Healthcare

When a hospital receptionist's email and a ventilator share the same network, every phishing email is a potential path to patient harm.

The Challenge

Healthcare faces life-critical cyber threats.

Patient Safety Risk

Ransomware attacks on healthcare networks force the cancellation of surgeries and diversion of emergency patients, directly endangering lives.

Medical Device Vulnerabilities

Connected medical devices run embedded operating systems that cannot be patched without recertification, creating permanent vulnerabilities on the clinical network.

Flat Hospital Networks

Many hospitals share a single network for clinical systems, medical devices, admin workstations, and guest Wi-Fi, enabling rapid ransomware propagation.

The Scenario

Scenario: Hospital Ransomware Attack

Ransomware enters through a phishing email opened on an administrative workstation. Within four hours, it propagates across the flat hospital network, encrypting clinical workstations, imaging systems, and electronic health records. Emergency departments divert patients to neighbouring hospitals. Surgical lists are cancelled for eleven days. Three MRI machines require complete rebuild because their embedded controllers were encrypted. With Firevault Control, the administrative network is physically separated from clinical systems and medical devices. The ransomware cannot propagate beyond the admin zone because the network path to clinical systems does not exist.

"The ransomware encrypted everything on our network in under four hours. Our MRI scanners, our patient records, even the pharmacy dispensing system. The only systems that survived were the ones that happened to be switched off that night."

Solution Blueprint

Physical protection for patient-critical systems.

Healthcare organisations gain physical isolation between administrative, clinical, and medical device networks. Ransomware cannot propagate from an email workstation to a ventilator because the network path does not exist. Clinical system recovery is guaranteed through air-gapped archives that ransomware cannot reach.

  • Physical isolation of medical devices from admin networks
  • Ransomware containment that protects patient safety
  • Multi-party authorisation involving clinical governance
  • Independent management communications for incident response
  • Continuous DSPT and NIS2 compliance evidence
  • Air-gapped recovery for rapid clinical service restoration
Fracture

Fracture — Emergency Clinical Isolation

Module 1 of 4

Physically disconnects compromised network zones to prevent ransomware propagation into clinical systems and medical devices. When a threat is detected, Fracture severs the path within seconds to protect patient-critical systems.

Key Capabilities

NHS Data Sovereignty

All clinical data and configurations remain within the agreed jurisdiction in secured Firevault Bunkers, meeting NHS data residency requirements.

Clinical Governance Access

Access to clinical systems requires authorisation from both IT and clinical governance teams, reflecting the dual nature of healthcare technology.

DSPT Compliance

Automated compliance logging maps directly to Data Security and Protection Toolkit requirements and NIS2 Article 21 outcomes for healthcare.

Cellular Management

Out-of-band management via cellular connectivity ensures control over hospital networks independent of the compromised infrastructure.

Patient Data Audit Trail

Every access to clinical systems and patient data paths is recorded in tamper-proof logs for regulatory and clinical governance audit.

Rapid Clinical Recovery

Air-gapped copies of clinical systems enable rapid restoration of patient-critical services without relying on network-connected backups.

Demo to Live

Adoption Guide

Step 1

Clinical Network Assessment

Map all network paths between admin systems, clinical applications, medical devices, and guest access to identify segmentation gaps and patient safety risks.

Step 2

Clinical Zone Design

Design physically separated zones for administration, clinical systems, medical devices, and imaging with Control modules at each boundary.

Step 3

Ward-Level Pilot

Deploy in a representative ward or department with full zone separation, controlled updates, and compliance logging to validate clinical workflows.

Step 4

Trust-Wide Deployment

Phased deployment across the trust with air-gapped recovery, continuous DSPT evidence generation, and 24/7 cellular management capability.
