F5 Networks Certified as Five-Star Vendor from CMP's VARBusiness Magazine

F5's Advantage Partner Program commended by leading technology publication

SEATTLE, March 19, 2007 - F5 Networks, Inc. (NASDAQ: FFIV), the global leader in Application Delivery Networking, today was recognized by CMP Technology's VARBusiness magazine as one of North America's top information-technology (IT) vendors in terms of partnership programs offered to solution providers.

F5 was certified as a Five-Star Partner, affirming the commitment and strength of its programs for IT integrators, resellers, and consultants. According to VARBusiness, vendors are honored for the way they monitor partner members' training and certification levels, the amount of business they generate, the amount of products or services they sell indirectly, and the number of dollars they invest in their programs, among other factors.

"We're thrilled to receive this high honor from VARBusiness," said Dean Darwin, Vice President of North America Channels at F5. "By combining a commitment to excellence, innovative solutions, partner rewards, and community support, F5 has a recipe that ensures partners thrive. Through the channel, we continue to build mutually beneficial relationships based on industry-leading technology and a singular dedication to success. A Five-Star rating proves we're on the right track with our partners, as well as our customers."

Of the 250+ vendor-program entries reviewed for the past year, only 60 companies received the coveted Five-Star rating in the magazine's 13th annual Partner Programs Guide survey. Past recipients of this respected distinction include Apple, IBM, Intel, and Microsoft. The year's guide appears in the March 19, 2007, issue of VARBusiness.

"We applaud vendors like F5 for demonstrating best practices and for the leadership roles they have achieved within the IT distribution channel," said VARBusiness editor Lawrence M. Walsh.
