Exhibit 99.1

                   Citrix Completes Acquisition of NetScaler;
            Delivers the ``Best Access Experience'' to Any Resource

     FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--Aug. 16, 2005--Citrix Systems, Inc.
(Nasdaq:CTXS), the global leader in access infrastructure solutions, today
announced it has completed the acquisition of privately held NetScaler Inc., a
global leader in high-performance application networking. The transaction is
valued at approximately $300 million in cash and stock and includes the
assumption of approximately $23 million in unvested stock options.
     This acquisition strengthens Citrix's customer value proposition by
improving the performance of any application delivered through the Citrix Access
Platform, the industry's most complete and integrated system that seamlessly
connects users, devices, and networks to enterprise resources. NetScaler
accelerates the performance of Web browser-based applications and e-commerce and
consumer Web sites by as much as 15 times.(a) NetScaler technologies will
enhance the Citrix Access Platform by significantly improving application
security, manageability, reliability, and availability of any application while
lowering the cost of operations.
     "With this acquisition, we are extending our best access experience value
to the entire range of Web-based applications, including enterprise,
browser-based, XML Web services, and others," said Mark Templeton, president and
chief executive officer for Citrix.
     "With the addition of the Citrix NetScaler Application Accelerator and
Application Switch, the Citrix Access Platform can significantly optimize the
customer's entire set of client/server, Web, desktop, or legacy enterprise
resources. This reduces their IT costs through increased server scalability and
availability, reduced back-end server loads, and increased network bandwidth
efficiency, all while increasing user satisfaction and productivity."
     NetScaler, with approximately 200 employees, including research and
development teams in Silicon Valley and India, will continue to operate from San
Jose, Calif., as the Application Networking Group of Citrix. B.V. Jagadeesh,
previously president and chief executive officer for NetScaler, will now report
to Mark Templeton as group vice president and general manager.
     In early 2003, Citrix outlined a strategy to expand its coverage of the
overall Access Infrastructure category by penetrating into adjacent high-growth
markets such as collaboration and VPN. Since that time, Citrix has completed
three acquisitions of best-of-breed companies. In 2004, Citrix acquired
Expertcity, now the Online Group, moving the company into the real-time
collaboration, desktop access and on-demand assistance market segments. Citrix
also acquired Net6, now the Gateways Group, extending Citrix's reach in the SSL
VPN (secure socket layer virtual private network) and IP (internet protocol)
telephony market segments. NetScaler is the latest acquisition, adding
innovative application networking technologies, including application
acceleration & optimization; application traffic management, and application
security. These technologies will allow end users to access enterprise resources
faster; they'll improve the service levels that IT departments provide to the
organizations they support; and they'll increase agility for businesses that run
on the Citrix Access Platform.
