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.

Excellent Managed IT and Cyber Security Support
I’ve been working with CLI Secure for several months now, and I couldn’t be happier with their service. As a business owner, having reliable IT support and strong cyber security is essential, and CLI Secure has delivered on both fronts brilliantly.
Their team is incredibly knowledgeable, responsive, and proactive. They don’t just fix problems when they arise — they actively help prevent them. Whether it’s setting up secure systems, monitoring our network, or providing clear advice on best practices, everything has been handled professionally and efficiently.
What really stands out is their customer-focused approach. They explain technical matters in plain English and always take the time to ensure we fully understand the solutions. Thanks to their expertise, we now have much better peace of mind regarding our data security and IT infrastructure.
I highly recommend CLI Secure to any business looking for trustworthy, high-quality managed IT and cyber security services in London. They’ve become a true partner rather than just a supplier.
Thank you, CLI Secure team! Keep up the great work.

Great Service and Friendly Staff
We recently used Cli Secure to set up the CCTV system and network infrastructure at our new warehouse. From the initial planning through to installation, the team was professional, responsive, and easy to work with. The work was completed to a high standard, and we're very happy with both the quality of the service and the support we received. We'd be happy to recommend them.
