Nevis Networks Names Charles Dauber President And Chief Executive Officer

Former Blue Coat Executive to Lead Nevis' Entry into Emerging LAN Security Market

SANTA CLARA, Calif - (July 18, 2005) - Nevis Networks, an emerging provider of LAN security systems, announced today that veteran network security executive Charles Dauber has been named president and chief executive officer. Dauber, who replaces former CEO Suresh Nihilani, will drive the successful penetration of Nevis' "Personal DMZ™" technology into the enterprise market.

(Editor's note: Please also see release issued today titled "Nevis Networks Secures Additional $12.5 Million in Financing.")

Dauber previously held the roles of vice president of marketing, vice president of security products, and vice president of corporate development at leading network security company Blue Coat Systems (NASDAQ: BCSI). Dauber took the lead in successfully repositioning and re-launching network caching vendor CacheFlow as Blue Coat Systems, creating the market-leading internal security company with over $120 million in annualized revenues. Prior to Blue Coat, Dauber was CEO of a broadband services provider and held marketing and sales positions at Copper Mountain Networks and Teradyne, Inc.

"We recruited Charles to Nevis because he has a very strong track record of rapidly building market share for new technologies. Charles' success in building Blue Coat into a market leader proved his personal leadership, technical vision, and deep security-market experience," said Pete Buhl, founding partner of BlueRun Ventures. "His ability to leverage Nevis' strong technology and its team is the catalyst for us to become the leading provider in this new LAN security market."

"Internal security is the biggest problem facing IT departments today. Existing LAN security alternatives aren't capable of addressing the complex issues involved in internal threats," said Dauber. "Nevis has very disruptive technology that for the first time truly enables enterprises to lock down those threats on the LAN. This is an outstanding opportunity to leverage my experience and knowledge in successfully bringing security companies to market. I'm thrilled to be joining Nevis, which is at the forefront of what I believe will prove to be a very large market opportunity."

A savvy dealmaker, Dauber successfully completed multiple acquisitions and over 15 technology partnerships at Blue Coat. Products introduced under his tenure have achieved numerous industry awards and are recognized market-share leaders in their respective classes. Dauber earned a combination degree in electrical engineering and marketing from the University of Texas at Austin.
