Cybersecurity & Infrastructure In-One

Network Security Clinic Ltd is a UK-based cybersecurity and infrastructure consultancy supporting organisations across the public and private sectors. We specialise in strengthening network security, improving operational resilience, and aligning technology environments with recognised industry standards.

Our work is grounded in established frameworks including ISO/IEC 27001, NCSC guidance, and Cyber Essentials. We focus on delivering practical, measurable improvements that enhance security posture without unnecessary complexity.

Founded by Mohamed Warssame, a network and security consultant with over 20 years of experience, the company is built on deep technical expertise across enterprise networking, cloud infrastructure, and secure systems design.

Professional experience spans both public and private sectors, including NHS, Ministry of Justice, Facebook, SmartFocus, and SunGard Availability Services — providing insight into highly regulated, high-availability, and large-scale environments.

We operate remotely across the UK and provide on-site consultancy support across the UK, Europe, the Middle East, and Africa where required.

Our Mission

Bridging Strategy and Implementation

Our mission is to bridge the gap between cybersecurity theory and real-world implementation. We help organisations translate compliance requirements and security frameworks into resilient, secure, and scalable infrastructure environments.

Every engagement is designed to strengthen operational resilience, reduce risk exposure, and support long-term infrastructure sustainability.

Our Approach

Structured. Risk-Driven. Vendor-Neutral.

We follow a structured methodology designed for growing organisations and enterprise environments. Our focus is clarity, prioritisation, and measurable outcomes.

We do not push products. We focus on outcomes that strengthen security posture and reduce long-term risk.

Our Values

What Guides Our Work

Cyber Essentials & Standards Alignment
