Wibhu Becomes Airtight Networks; Secures $10.25 Million To Deploy Industry’s First WiFi Firewall

MOUNTAIN VIEW, CA, Nov. 15, 2004 – Wibhu Technologies today announced it has changed its name to AirTight Networks and has obtained $10.25 million in financing led by Walden International and joined by three other prominent venture capital companies: Blueprint Ventures, Granite Ventures and Trident Capital. The Series A funding will allow AirTight to ramp up sales and marketing efforts to support the launch of its new WiFi Firewall, which will be unveiled November 30, 2004, at the WiFi Planet show in San Jose, CA.

AirTight also announced the expansion of its management team with the arrival of veteran WLAN industry leader David C. King as CEO, and experienced security industry sales executive Brad Taylor as vice president-worldwide sales. In addition, AirTight has added Danial Faizullabhoy, managing director of Walden International, Eric Zimits, managing director of Granite Ventures, and Mark Smith, former vice president-worldwide sales for NetScreen Technologies, to its Board of Directors. Joining the company as advisors are Bart Schachter, founding and managing partner of Blueprint Ventures, and Christopher (Woody) Marshall, managing director of Trident Capital.

“We have carefully chosen the name AirTight Networks because our solution provides corporate data networks complete protection from over-the-air attacks,” said King. “We firmly believe, and will prove through comparative testing, that the AirTight solution represents a turning point in security – a WiFi firewall that provides ‘air-tight’ protection against intruders.”

King, the former chairman, president and CEO of Proxim, Inc. has been the driving strategic force behind AirTight since joining the company earlier this year. He joined Proxim in 1992 as vice president of marketing, and was appointed president and CEO in July of 1993. He took the company public in December of that year as the first publicly traded WLAN company. During his tenure, Proxim grew from $4 million to more than $100 million in annual sales. Before Proxim, King was vice president-marketing and customer services at Vitalink Communications Corp., a pioneer in wide area data networking. He also served as a senior manager at McKinsey & Co.’s San Francisco office, leading the consulting firm’s high technology and health care practices.

Taylor, AirTight’s new vice president-worldwide sales, has 18 years experience in sales force development, operations and venture funding. He was most recently executive vice president- sales and marketing for Digital Evolution, a software provider for web services management and security. Before Digital Evolution, Taylor spent eight years at RSA Security, initially as director of sales and then as founder of RSA Security Ventures.

AirTight clearly has the technology chops and its management team has already demonstrated an impressive ability to execute. With the WiFi security market ready for prime time, AirTight is strongly positioned to secure an ‘air-tight’ lock on the market.”
