Peribit Networks Ranked Second Fastest-Growing Private Company In Silicon Valley

Silicon Valley/San Jose Business Journal Honors WAN Optimization Leader Among 50 Top Performing Companies

SANTA CLARA, CA – October 18, 2004 - Peribit Networks, the leader in application delivery over the WAN, today announced it has been recognized as the “Second Fastest Growing Private Company in Silicon Valley” by the San Jose Business Journal. PriceWaterhouseCoopers verified the financial data for all participating companies, which included search engine giant Google. Hundreds of Silicon Valley’s leading companies were evaluated and ranked by percentage revenue growth during the period of 2001 through 2003 before the final top 50 companies were selected for this special edition of the journal published today.

The company attributes its tremendous growth to the growing demand for enterprises to dramatically improve application performance across their wide area networks without having to resort to prohibitively expensive and complex network upgrades. Peribit’s award-winning Sequence Reducer™ and Sequence Mirror™ platforms and PeriSphere™ architecture help customers increase available WAN bandwidth, acceleration applications, and prioritize business-critical traffic.

“This recognition as one of the fastest-growing companies in the fiercely competitive and highly innovative Silicon Valley further validates that our rapidly growing and diverse customer base is deriving significant benefits from our WAN application delivery solutions,” says Jef Graham, president and CEO of Peribit. “Companies deploying Peribit solutions are realizing major productivity gains and more efficient utilization of their network infrastructures, which translate into substantial cost savings and a rapid return on investment.”
