FORT LAUDERDALE, Fla. -- Citrix Systems, Inc. (Nasdaq:CTXS), the global leader in application delivery infrastructure, today announced continued revenue growth and market share gains in the application delivery controller (ADC) worldwide market according to a new report from Gartner titled, "Market Share: Application Acceleration Equipment, Worldwide, 1Q07"1. From Q406 to Q107 the Citrix[R] NetScaler[R] web application delivery product line posted market share gains in both the overall $1 billion application delivery controller segment as well as the advanced platform application delivery controller (AP-ADC)2 sub-segment.

Growing enterprise customer demand for highly integrated solutions with greater scalability and fault tolerance has become a key driver in the evolution of the web application delivery market.

With market-leading application layer performance, Citrix NetScaler has an established track record of delivering many of the world's most demanding and high-profile web applications, making it a proven choice for enterprises of all sizes that want to accelerate the performance of business-critical web applications, secure sensitive application data and lower the cost of delivering web applications to any user in any location.

The most recent NetScaler 8.0 release continues to push new standards in controlling application and user specific policies with its AppExpert Policy Framework, and built-in end user experience monitoring, as well as becoming the first application delivery controller on the market to offer a fully integrated SSL VPN and web application firewall. These advances give administrators unprecedented control over the entire web application delivery process and enable them to improve the experience of corporate application users, no matter how complex the environment.
