Citrix XenDesktop 4 Wins InfoWorld 2010 Technology of the Year Award

Citrix Systems, Inc. (NASDAQ: CTXS) today announced that Citrix® XenDesktop™ 4 has been honored as an InfoWorld 2010 Technology of the Year Award winner. Selected by InfoWorld Test Center editors and reviewers, the annual awards identify the best and most innovative products on the IT landscape. Winners are drawn from all of the products tested during the past year, with the final selections made by InfoWorld’s Test Center staff. All products reviewed by the Test Center are eligible to win.

XenDesktop 4 is a comprehensive desktop virtualization solution that delivers a complete Windows desktop experience as an on-demand service to any user, anywhere, making virtual desktops a mainstream reality for hundreds of millions of corporate employees for the first time ever. Unlike first-generation VDI-only solutions that were applicable only to a narrow set of users, XenDesktop 4 with its new FlexCast™ delivery technology is the first product in the industry to support every major desktop virtualization model in a single, integrated solution – a breakthrough that improves ROI, simplifies management and extends the benefits of virtualization to every employee in the enterprise. XenDesktop 4 further simplifies desktop computing by integrating all the functionality of Citrix XenApp™, enabling customers to deliver on-demand applications as a seamless part of their overall desktop strategy. XenDesktop’s award-winning HDX™ technology also ensures every user receives a high-definition experience. By using up to 90 percent less bandwidth than competing solutions, XenDesktop with HDX is the only solution to deliver a high-definition experience over WAN connections, and can support up to three times more users on the same LAN.

“InfoWorld Technology of the Year award winners are not just the best products in their class, but the products that are leading the way in the technology categories that businesses and IT professionals should care most about,” InfoWorld Test Center Executive Editor Doug Dineley said. “These are the products that are changing the way businesses operate and how people work.”

“We are honored that InfoWorld Test Center editor and reviewers recognized XenDesktop 4 as an InfoWorld 2010 Technology of the Year Award winner. It’s a testament not only to the strength of our innovative solution, but to the growing mainstream adoption of desktop virtualization overall,” said Raj Dhingra, group vice president and general manager, XenDesktop product group at Citrix Systems. “XenDesktop 4 has proven to be a market-leading and award-winning desktop virtualization product and to share this win with other top-notch solutions, like Intel’s Nehalem processor, Microsoft Windows 7 and Apple’s iPhone OS and AppStore is a true achievement.”
