Defence Holdings is pleased to announce the appointment of Jim Clover OBE to its Advisory Board. Jim is a former UK national security and cyber operations senior leader, with over 25 years’ experience across cyber operations, open-source intelligence and digital forensics. He previously served as Deputy Director of Cyber Operations within HM Government, with senior responsibility for cyber and digital activity in support of UK Defence and national security objectives, including work with allied partners. He was awarded an OBE for services to UK and overseas national security. Jim’s appointment significantly strengthens the Advisory Board’s depth of experience across Defence, national security and cyber operations. It directly supports the expansion of Defence Technologies’ National Security pillar, as the Group builds defence-led, mission-aligned software capability for real operational environments. As software, data and decision advantage continue to shape modern Defence, board-level insight grounded in operational delivery is critical. Jim’s experience brings valuable perspective as Defence Holdings advances from capability development into deployment-aligned delivery.

Translating new regulatory standards into a sustainable cyber strategy is now a priority for organisations across the UK’s Critical National Infrastructure. As threats escalate and compliance requirements expand, keeping pace with both IT and OT is no longer optional. From IEC 62443 and the Cyber Security and Resilience Bill to the updated NIS regulations, the scope of responsibility continues to grow. Our four phase approach, aligned to the NCSC Cyber Assessment Framework, helps Operators of Essential Services and their supply chains move beyond basic compliance towards long term resilience. Governance, risk management, supply chain assurance, zero trust access, continuous monitoring, and tested response plans all play a defined role in building a secure and sustainable foundation. You can read the whole whitepaper here: https://lnkd.in/eaVqCPyM If you would like to understand how these standards apply to your organisation and where the key gaps and opportunities may lie, speak to our CNI specialists today: https://lnkd.in/e6Wubm_y #CyberSecurity #CriticalNationalInfrastructure #CNI #NISRegulations #IEC62443 #CyberResilience #RiskManagement #OperationalTechnology #InformationSecurity #UKBusiness
