Internal Network Security • Penetration Testing • ISO Readiness
A healthcare organization handling sensitive patient data required a comprehensive internal security assessment to evaluate the safety of their network infrastructure, Wi-Fi environment, and internally connected systems. The objective was to identify security gaps, strengthen defenses, and prepare for ISO certification while ensuring patient data confidentiality and trust.
The healthcare environment depended on internal Wi-Fi and networked systems, but security controls had not been formally assessed. Weak Wi-Fi and router configurations, unpatched Windows and macOS systems, and limited security documentation increased the risk of unauthorized access, data exposure, and compliance gaps.
The healthcare client required a focused internal security audit to support ISO certification and demonstrate secure handling of patient data. They needed an assessment of Wi-Fi, network infrastructure, and connected systems, along with penetration testing to identify vulnerabilities. The engagement also included remediation guidance, patch management support, and a credible security report to strengthen compliance readiness and overall cyber resilience.
Engaged with IT and management teams to understand the current network architecture, connected systems, data flow, and define the scope and approach for the internal security audit.
Reviewed Wi-Fi architecture and encryption standards, router and access point configurations, network segmentation and internal access controls.
Identified all systems connected to the internal network, including: Windows workstations, macOS devices, medical and administrative systems.
Discovered critical issues such as: default credentials on Wi-Fi/router admin panels, outdated Windows and macOS operating systems, missing security patches and update misconfigurations.
Performed controlled penetration testing to validate exploitability, assess lateral movement risks within the internal network, and evaluate impact on sensitive patient data systems.
Provided vulnerability validation, risk assessment, and structured vulnerability management guidance.
Delivered internal audit reports, vulnerability findings, remediation recommendations, and ISO-ready certification documentation.
