A leading healthcare provider with 500+ endpoints across 12 locations engaged Codesecure for internal and external network VAPT. We identified critical vulnerabilities including unpatched systems, weak VLAN segmentation between medical devices and IT infrastructure, and misconfigured firewall rules.
Case Study / Network VAPT for a Healthcare Provider
Client Overview
A leading healthcare provider operating across 12 locations with a mix of modern IT infrastructure and legacy medical equipment. Their network had grown organically, creating flat segments where medical devices, staff workstations, and administrative systems shared the same VLANs. A previous compliance audit flagged network security concerns.
Challenge
The client needed to understand their actual security posture before an upcoming HIPAA audit. Legacy medical devices that could not be patched, 24/7 operational requirements, and distributed locations made traditional testing approaches difficult. They required a VAPT partner experienced in healthcare environments.
Our Approach
Codesecure conducted a comprehensive network VAPT engagement covering the following areas:
• External perimeter testing of public-facing services and IP ranges
• Internal network VAPT across all 12 locations via VPN
• Vulnerability scanning of 500+ endpoints including servers, workstations, and network devices
• Manual exploitation to assess real-world impact
• Firewall rule review covering ACLs, NAT policies, and inter-VLAN routing
• Wireless security assessment
• Detailed CVSS-scored reporting with prioritised remediation
Results
47 vulnerabilities were identified — 8 critical, 15 high, and 24 medium severity.
Critical findings included:
• Unpatched VPN appliance with a known RCE exploit
• Default credentials on network switches
• Medical device VLANs accessible from guest Wi-Fi
• Exposed RDP on external perimeter
All critical and high findings were remediated within the agreed timeline. A revalidation assessment confirmed successful remediation and an improved security posture across all locations.
Conclusion
Regular network VAPT is essential for healthcare organisations managing sensitive patient data and connected medical devices. By identifying and remediating critical vulnerabilities, the client reduced their attack surface and strengthened HIPAA compliance. Contact Codesecure for a comprehensive network security assessment.
