Explore." lang: en-GB --- Healthcare # 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. - Ransomware on clinical systems - Medical device (IoMT) compromise - Patient record exfiltration - Third-party vendor access Back to Control: https://fire-vault.com/solutions/control Image: Clinical records and hospital systems protected offline (https://fire-vault.com/assets/oss-industry-healthcare-CpzjVCJ-.jpg) The exposure in numbers 01 Medical device network isolation 100% Medical device network isolation 02 Direct paths between clinical and admin networks Zero Direct paths between clinical and admin networks 03 Clinical zones with independent governance 5 Clinical zones with independent governance 04 DSPT and NIS2 compliance evidence Full DSPT and NIS2 compliance evidence The Challenge ## Healthcare faces life-critical cyber threats. 01 ### Patient Safety Risk Ransomware attacks on healthcare networks force the cancellation of surgeries and diversion of emergency patients, directly endangering lives. 02 ### Medical Device Vulnerabilities Connected medical devices run embedded operating systems that cannot be patched without recertification, creating permanent vulnerabilities on the clinical network. 03 ### Flat Hospital Networks Many hospitals share a single network for clinical systems, medical devices, admin workstations, and guest Wi-Fi, enabling rapid ransomware propagation. 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 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 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." Module deployment · healthcare network ## Where each Control module is deployed across clinical systems, devices and research. Healthcare networks carry a corporate estate, clinical systems, a long tail of medical devices and a research environment. Control puts a real boundary at every change of trust so a compromise in one estate does not become a clinical incident. Grounded in NHS DSPT, HSCN reference architecture, IEC 80001 and NIST SP 1800-30.
