Riverbed Positioned in the Leaders Quadrant of Leading Analyst Firm's Magic Quadrant for WAN Optimization Controllers

SAN FRANCISCO, CA, Jul 13 (MARKET WIRE) --
Riverbed Technology (NASDAQ: RVBD), the IT infrastructure performance
company for networks, applications and storage, today announced that it
has been positioned by Gartner in the leaders quadrant in the "WAN
Optimization Controller (WOC) Magic Quadrant, 2009" published in June
2009 and authored by Andy Rolfe, Joe Skorupa and Severine Real. According
to Gartner, "Leaders exhibit an ability to shape the market by
introducing additional capabilities in their product offerings and by
raising awareness of the importance of these features. We expect a Leader
to be growing 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."

According to the report, "Optimization techniques for wide-area networks
(WANs) can improve most organizations' application response times,
particularly where network latency is high, which is often due to
centralization of servers and IT resources. Typically, WAN optimization
controllers (WOCs) serve to prevent network latency having a severe impact
on the performance of applications and underlying protocols. Through data
reduction and prioritization techniques, WOCs can also help organizations
avoid costly bandwidth upgrades."

Riverbed(R) WAN optimization solutions enable organizations of all sizes
to overcome a wide range of IT infrastructure performance bottlenecks,
including poor application performance, slow database backups and
insufficient bandwidth at remote sites. By speeding the performance of
applications between data centers, remote offices and mobile workers by up
to 100 times, the Riverbed award-winning Steelhead(R) products enable
companies to consolidate IT, improve backup and replication processes to
ensure data integrity, and improve staff productivity and collaboration.

"Our leadership is reflected in our customer base of over 6,000
organizations. For the past 5 years, we've maintained leadership in the
WAN optimization market because we stay focused on addressing customers'
ever-changing needs, which allows us to continually develop superior
technology," said Eric Wolford, senior vice president, marketing and
business development at Riverbed. "We have been recognized for our
excellent product reputation, broad application support, ease of
installation and our managed service provider relationships. As the
market matures we will continue to align our product and distribution
strategies to support growing global organizations."

The 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. To
