Business Wire, Oct 11, 2006

Evaluation Based on Completeness of Vision and Ability to Execute

SAN FRANCISCO -- Riverbed Technology, Inc. (Nasdaq:RVBD) announced today that it has been positioned by Gartner in the leaders quadrant in the "WAN Optimization Controller (WOC) Magic Quadrant"1 published in October 2006 and authored by Andy Rolfe and Joe Skorupa. This report positions vendors in one of four quadrants based on the companies' vision and ability to execute on that vision. The four quadrants are Leaders, Challengers, Visionaries and Niche Players.

According to Gartner, Leaders exhibit an ability to shape the market by introducing additional capabilities in their product offering and by raising awareness of the importance of these features. Gartner expects a Leader to be growing market share, or the market as a whole, and to have solutions that resonate with an increasing number of enterprises. Leaders in the WOC market need to have a broad feature set, including QoS, generic compression, protocol acceleration and file system acceleration, with the majority of features proven in substantial real-world implementations. They also need to be able to offer sales and support on a global basis.
