By working with us our customers gain access to a wide range of managed services, professional services, and training across Cloud, Networks, Managed Cyber Security, and Unified Communications and collaboration technologies.

Founded in 1996, Claranet has evolved from a pioneering ISP (Internet Service Provider) into a leading technology services provider with global reach. The company has annualised revenues of circa £400 million, over 10,000 customers, and more than 2,500 employees.

The company’s ambitious growth strategy has led to numerous acquisitions and Claranet consistently appears in The Sunday Times Top Track 250 as one of the fastest growing privately-owned businesses in the UK. This international success is driven by local service, out of local offices, using a mixture of local and international infrastructure, including public clouds.

Claranet was positioned for the second year running in Gartner’s Magic Quadrant for Data Centre Outsourcing and Hybrid Infrastructure Managed Services, Europe, introduced in 2018. This follows Claranet’s inclusion as a ‘Leader’ in the Magic Quadrant for Managed Hybrid Cloud Hosting, Europe for five years running, 2013-2017. The company was also named a Market Leader across two categories in the 2020 ISG Provider Lens™ for Public Cloud Solutions and Services Quadrant report.
