Reseller Ultima Business Solutions has announced profits of £1m for its 2002 financial year.
The announcement follows the company's investment of £4m in a 24-hour support centre, a new London office and an increase in its security focus.
"The real growth area of our business has been our managed security service and security infrastructure sales," said Darron Antill, Ultima's managing director.
"Our new network operation centre houses our managed services offering, which has taken off, and our City of London office has brought us nearer to new and existing customers."
The company is also predicting strong growth for 2003 after winning 28 new contracts through its London office in a 16-week period.
Ultima has a broad product offering, with reseller agreements with HP, Check Point, Nokia, Microsoft, Citrix and IBM.
David Ellis, director of e-security at Ultima distribution partner Unipalm, said that managed security services are beginning to take off for resellers that offer flexibility and fast return on investments to customers.
But he warned: "The service level agreement (SLA) needs to be carefully considered, because if the reseller cannot meet the SLA it is a serious problem for them and for confidence in managed security services."
