Demonstrating its latest next-generation firewalls in Booth #427, Palo Alto Networks returns to Interop after winning the coveted Best of Interop 2008 Grand Prize Award with significant customer and industry traction and growth over the past year. Despite the economic downturn, the company has continued to accelerate customer acquisition, beating the annual revenue plan.

"Palo Alto Networks has had a great year since being chosen as the Best of Interop Grand Prize winner last year," said Lenny Heymann, Interop General Manager. "We are glad to have the company back active in the event this year, demonstrating its latest advancements in firewall technology and speaking on the troubles of today's legacy firewalls. We look forward to hearing some of Lee's insights on the panel."

Over the past year, Palo Alto Networks has seen significant traction and growth on the customer front, adding new customers such as Greenhill & Co., Virginia Commonwealth University (VCU) Health System, ThedaCare, the Museum of Modern Art and Cricket Wireless, and continues to expand in major regions internationally, as well. In addition, since last year's Interop, the company has named Lane Bess, former EVP and GM of Trend Micro, as CEO to lead the company through this critical expansion; and has raised an additional $37M in funding to fuel its rapid growth. The industry has also validated the company's achievements and innovations with significant award recognition, including ZDNet's Most Influential BizTech Product Award, CRN's Top Executive Award for CEO Bess, InformationWeek's Innovators & Influencers Award for CTO Nir Zuk, and InformationWeek's Start Up 50 Award. Palo Alto Networks also earned Interop 2008's Best of Interop Award in the Security Category.

"The industry has had its eye on Palo Alto Networks since our recognition at last year's Interop, and over the past year the company has not disappointed," said CEO Bess. "We are very proud of the achievements of the company, and the validation we have received from the industry and customers for our unique approach to innovative firewall technology. It's fair to say that Interop 2008's Grand Prize Award was a landmark event for the company, and we are excited by our trajectory as we power through a difficult economy and are exceeding the milestones we previously set."
