Digital Manufacturing
Warren Services, a precision engineering and fabrication company based in Thetford, engaged MTC to assess its cyber resilience through the MTC Cyber Resilience Assessment (CRA). As part of their journey into digital manufacturing, Warren Services has invested in connected equipment and cloud-based applications to improve efficiency and support advanced manufacturing processes. This transition has increased the importance of robust cyber security measures to protect both operational technology and business systems.
The CRA is designed to help manufacturers understand their exposure to cyber risks and strengthen their defences against potential threats. Using a methodology aligned with the National Cyber Security Centre’s Cyber Assurance Framework (CAF) and mapped to the NIST Cyber Security Framework, the assessment reviewed Warren Services’ governance, processes, and technical controls. The project aimed to provide practical, vendor-agnostic recommendations to enhance resilience without prescribing specific technologies. This proactive approach reflects Warren Services’ commitment to safeguarding its operations and intellectual property in an increasingly connected manufacturing environment.
The cyber resilience assessment provided a comprehensive and practical evaluation of our security posture, highlighting key risks and resilience gaps across people, processes and technology. The clear, prioritised recommendations enabled us to strengthen our defences, improve incident response and recovery capabilities and align cyber resilience efforts with our broader business objectives.

The challenge
Like many UK manufacturers, Warren Services faces growing cyber threats, with recent high-profile incidents in the sector highlighting the potential for severe disruption.
While the company had already achieved Cyber Essentials Plus (CE+) certification, it recognised that CE+ does not fully address areas such as business continuity and intrusion detection. The challenge was to identify gaps beyond baseline compliance and develop a roadmap for improvement.
Warren Services needed to ensure its IT and operational technology environments remained secure as it expanded digital connectivity on the shop floor. Key concerns included preventing unauthorised access, managing supply chain risks, and maintaining resilience against incidents that could halt production or compromise sensitive data.
MTC’s solution
MTC conducted a comprehensive Cyber Resilience Assessment, benchmarking Warren Services against best practice frameworks. The assessment highlighted strengths, including robust cyber hygiene, secure cloud backups, and effective segregation between office and manufacturing networks. The assessment identified priority areas for improvement, but we cannot share the details for obvious reasons.
MTC provided tailored recommendations, such as implementing cost-effective cyber security technologies. These range from open-source solutions to commercial technologies bundled with other services, enhancing endpoint protection and network monitoring. These measures were designed to improve detection capabilities, reduce recovery times, and future-proof the business against emerging threats.

The outcome
The CRA confirmed that Warren Services is “punching above its weight” in cyber resilience compared to similar-sized enterprises, thanks to strong leadership and a proactive IT team. The company now has a clear roadmap to strengthen its defences further, enhancing intrusion detection, business continuity, and supply chain security. By acting on MTC’s recommendations, Warren Services expects to increase its resilience score significantly, particularly in the Detect and Respond functions of the NIST framework.
The assessment has also further raised awareness across the organisation, ensuring cyber risk is now part of strategic planning. This case highlights how MTC’s CRA helps manufacturers go beyond compliance to achieve robust, practical cyber resilience.
Our customers like the holistic approach of the CRA, which provides an independent 'mirror' to highlight the strengths and weaknesses in their cyber defences.
This clarity empowers frontline teams to build a compelling business case and gain board-level support for further improving cyber resilience.
