Citrix NetScaler Gains Share in Web Application Delivery Market with Fastest Revenue Growth Rate Among Market Share Leaders

Business Wire, June 29, 2006

FORT LAUDERDALE, Fla. -- Citrix Systems, Inc. (Nasdaq: CTXS), the global leader in access infrastructure solutions, today announced market-leading growth in the $209M Application Delivery Controller (ADC) market according to a new report from Gartner titled "Market Share: Application Acceleration Equipment, Worldwide 1Q'06"(1). From Q405 to Q106 the Citrix(R) NetScaler(R) product line posted the highest overall growth rate of all the market share leaders named in the report based on worldwide market share. According to Gartner estimates, Citrix was one of only two vendors to increase in worldwide market share and revenue in both the overall Application Delivery Controller market (ADC)(2) and the Advanced Platforms ADC sub-segment (AP-ADC)(3).

The growing trend among enterprise customers to centralize servers and deploy web-enabled intranet applications has resulted in a strong demand for solutions that improve the performance, security and availability of these applications. The Citrix NetScaler solution is ideally suited to meet this demand by tightly integrating advanced traffic management capabilities with state-of-the-art application acceleration and security technology into a single easy-to-deploy network appliance. Additionally, since Citrix NetScaler's single, unified device takes the place of a number of point solutions, overall network infrastructures are simplified, and operational costs are reduced.

"The NetScaler product line has long been a technology leader in the market for advanced web application delivery systems," said Wes Wasson, vice president of marketing and product strategy, Application Networking Group, Citrix. "Since acquiring NetScaler less than one year ago, Citrix has continued to increase that technology leadership while dramatically expanding its market reach through the extensive Citrix worldwide distribution channel. With an estimated 75 percent of all Internet users now going through a Citrix NetScaler system each day, Citrix is well positioned to continue its success in this high-growth market."

Since completing the acquisition of NetScaler in August of 2005, Citrix has increased market share by expanding the reach of the NetScaler product line through its worldwide distribution channel - one of the most extensive and developed distribution channels in the industry. Additionally, market share gains have been influenced by the exposure of the NetScaler product line to the vast Citrix installed base, which counts more than 180,000 customers worldwide.
