Experience you can rely on
CNS was founded in 1991 to give growing businesses access to the kind of IT expertise usually only available to large organisations. We have supported clients through every generation of business technology, from Wang office systems to today's cloud services.
Predicting growth and finding capital for IT infrastructure is hard. That's why we focus on flexible services that let you pay for what you need today, and scale when you're ready.
Today we provide a 24/7 fixed-cost helpdesk, Microsoft 365 and cloud services, security, backup, telephony and networking to businesses across London and the South East.
