Written by the company
CLI Secure is a London-based managed IT, cyber security and connectivity partner for growing UK businesses. We bring managed IT support, 24/7 cyber security (EDR, MDR and SOC monitoring built in, not sold as an add-on), Microsoft 365 & cloud management, network consultancy, CCTV, data cabling and business connectivity together under one accountable team — so there's no more finger-pointing between vendors. Clients get a 4-minute average response time, a 24/7 UK-based helpdesk answered by real engineers (never offshore scripts), 99.98% uptime across managed estates, and a dedicated vCIO who aligns IT with where the business is actually heading. We offer same-day onsite consultancy across Greater London, IT support anywhere in England, and remote support across Europe — with no lock-in contracts, so clients stay because the service works, not because they're tied in.

We have been working with CLI Secure…
We have been working with CLI Secure for many years, and throughout that time, they have consistently provided an excellent level of service. From IT support to CCTV installations, their team has always been professional, reliable, and helpful.
We recently worked with them again to install CCTV and network infrastructure at our new warehouse. From the initial planning stages through to completion, the whole process was handled efficiently and professionally. The team was responsive, knowledgeable, and made sure everything was completed to a high standard.
Their customer service and aftercare have also been excellent, and their pricing has always remained competitive. It is clear that they genuinely care about their customers and the quality of their work.
We are extremely happy with the service we have received over the years and would have no hesitation in recommending CLI Secure to anyone looking for a reliable and professional IT and security solutions provider. A big thank you to the entire CLI Secure team!
