CLI Secure is a London-based Managed Service Provider (MSP) delivering fully managed IT for small and mid-sized businesses. We take complete ownership of your technology — so you get reliable, secure, well-run IT without hiring or managing an internal team.
Our fully managed service, powered by the CLI 360 platform, spans the entire lifecycle of your IT: designing and setting up your infrastructure, keeping it maintained and patched, running your day-to-day operations, and supporting every user through a 24/7 helpdesk. It also includes the essentials most businesses can't afford to get wrong — email and Microsoft 365 management, backup and disaster recovery, and layered cyber security.
Whether you're setting up IT for a new office, migrating to the cloud, or replacing a provider that's letting you down, we deliver it with zero downtime — and then run it for you, backed by written SLAs and a dedicated London team.

Great IT isn't a one-off project — it's an ongoing discipline. We start by setting up and hardening your infrastructure: servers, network, Wi-Fi, firewalls, cloud and devices, all configured to best practice.
Then we take over the day-to-day management — monitoring, patching, backups, email administration and user support — while our security controls run quietly in the background. Every change is documented, every incident is logged, and every month you get clear reporting on what we did and why.
