Overview

Computer Network Consultants Ltd (commonly known as CNC) is a United Kingdom-based IT managed service provider that was originally established in 1996. The company built its reputation delivering IT support, networking and cyber services to small and medium-sized businesses across Sussex and Hampshire in southern England. Its service portfolio has historically centred on managed IT, LAN and Wi-Fi networking, IT security, Microsoft Office 365 and Teams, hosting and colocation, and backup as a service. In 2023 the business was acquired by FluidOne, a UK security-first technology partner that provides integrated cyber, IT and secure networking services. Following the acquisition, CNC was integrated into the FluidOne Group and now operates as the Brighton branch of FluidOne's Business IT division, part of the group's Business IT centre of excellence. The Brighton branch continues to serve local and regional clients while benefiting from the wider group's scale, expertise and portfolio. As part of FluidOne, the former CNC operation positions itself as an award-winning IT and cyber company that simplifies technology for businesses. It emphasises tailored, secure Connected Cloud solutions intended to improve efficiency, productivity, long-term growth and AI-enablement. The team is made up of certified experts who provide ongoing support and guidance, with a stated commitment to people-centred relationships with clients, staff and the wider community. The Brighton branch offers a range of services including Modern Workplace, Microsoft Office 365 and Teams, IT Security, Hosting and Colocation, IT Managed Services, Backup as a Service, and LAN and Wi-Fi solutions. Its networking practice covers design, build, ongoing management, monitoring, maintenance and support, as well as cabling, Wi-Fi installation and comms room organisation. The business serves clients across all industries, with a particular focus on small and medium-sized organisations in Sussex and Hampshire. FluidOne itself is a leading UK-based security-first technology partner serving more than 2,000 businesses and 200 channel resellers, with a strong company culture enjoyed by 460 staff and a turnover in excess of £100m. The group consistently reports one of the highest Net Promoter Scores in the industry. CNC's integration into FluidOne reflects the broader consolidation trend in the UK managed IT and cyber services market, where regional providers join larger platforms to offer broader capabilities and greater scale.
