Lumison was a UK Managed Services Provider based in Edinburgh, Scotland. Acquired by Bridgepoint Development Capital with 3 other companies to form Pulsant - a company headquartered in Reading, Berkshire
It was known as edNET from 1996 to 2004 and Pulsant from 2012. They primarily offer fully managed network solutions and hosted products to SMEs.
Lumison was founded in Leith as edNET in 1996, where its head office remains. It rebranded to the name Lumison in August 2004, and opened a dedicated datacentre on a greenfield site in Newbridge, Edinburgh in October 2004 and added a London Datacentre in Croydon, South London in 2008. This has enabled Lumison to provide additional rackspace for managed hosting, dedicated servers, virtualised servers and colocation (colo).
In October 2010, a majority stake in Lumison was acquired by Bridgepoint Development Capital in order to fuel growth from its existing position as a Managed IT Services provider into a significant player as a mid-market IT services firm in the UK. Further growth came through the acquisition of Colocation services company, BlueSquare Data Services, and DediPower Managed Hosting Services in 2011. The business has since rebranded under the name of Pulsant. The company now has a turnover of approximately £30m with 130 staff across 5 UK locations. There are 8 data centres in UK and sites in United States, Amsterdam, and Hong Kong.
