Speaking at the company's European iForum conference, chief technology officer Bob Kruger revealed that a Linux version of Citrix Secure Gateway (CSG) was scheduled for release later this year.

"People who have some trepidation about putting Windows in the DMZ are happier putting Linux in there," he said.

CSG, which was originally developed in the company's Sydney research labs, is used to provide secure access to Citrix's application hosting servers.

Concerns over security have been an ongoing problem for the Windows platform. Last year, Microsoft was forced to halt new development for a month to conduct a complete security review of all Windows code.

Security fears have also driven an increasing interest in Linux, in part because of its open source development model, which makes it easier to identify potential vulnerabilities, and in part because of its tightly integrated user access system, which makes deploying virus code more difficult.
