Irish ICT firm Calyx has signed a deal with the Irish Stock Exchange (ISE) to provide it with a range of security solutions.

Under the agreement Calyx is providing the Irish Stock Exchange with a solution to tackle the large amount of spam (accounting for 90 percent of inbound mail) that was coming through to staff at the ISE, as well as a web security solution.

For e-mail security Calyx recommended a solution from IronPort, a subsidiary of Cisco. IronPort's C100 stops spam at the gateway so it doesn't filter through the network. The ISE said the IronPort solution greatly reduced the amount of spam coming through and so Calyx also suggested the IronPort S-Series Web Security device to deal with the organisation's web security needs.

A key requirement for the ISE was reverse proxy look-ups for web traffic. The organisation also required a reputation filter on a web proxy which would be able to cache and also to deal with viruses, phishing and spyware attack.
"We have been delighted with the success of both implementations; we now have two single devices which have replaced multiple devices in previous solutions. This has provided savings both from a cost and time perspective. Calyx and IronPort has helped us to resolve our issues with inbound spam, trusted sites and web related threats," said David Garrett, IT Operations Manager at the ISE, in a statement.

Calyx employs over 500 people across 12 locations in Ireland and the UK. Calyx posted a 54 percent increase in turnover to EUR135 million in 2007. The company said its turnover more than trebled over the last two years but declined to give a profit figure for 2007. It made a pretax profit of EUR2.2 million in 2006, up 29 percent on the previous year.

At the end of March the firm announced it was rebranding its nine divisions, which include IT security firm Entropy, under the Calyx name.
