London enterprise provider with its own carrier-class network, supplying connectivity, cloud, cyber security and IT services to UK organisations.
About Exponential-e
Exponential-e works with organisations rather than households. The London company says it runs its own carrier-class network, built to the standard telecoms carriers use, along with a UK-based security operations centre, and that more than 3,000 organisations rely on its group.
Connectivity is one strand. It offers business internet and leased lines, SD-WAN, managed Wi-Fi, 4G data SIMs for connected devices, satellite broadband and HSCN, the secure network used across health and social care. Alongside that sit private and public cloud, Microsoft Azure services, colocation, backup and disaster recovery.
The wider group also includes Vysiion, Xpertex, EXPO.e and EXPO.e Networks. Exponential-e Ltd was incorporated in July 2002, and its registered office is on Leman Street in London.
