CONCORD, Mass. -- RSA Security's Arthur Coviello Brings Seasoned Leadership and Security Market Expertise to Help Crossbeam Accelerate Revenue Growth in 2005

Crossbeam Systems(R) Inc., the leader in protecting the world's largest networks, today announced that it beat all of its business targets for 2004, including adding more than 200 new customers and recording its third consecutive year of doubling revenue. The company also announced that it has named Arthur Coviello, Jr., president and CEO of RSA Security (NASDAQ: RSAS), to its board of directors.

As the pioneer of integrated, best-of-breed security devices, Crossbeam capitalized on the increase in security spending and rapid market shift away from single function security appliances in 2004 and completed a record financial year. Notable accomplishments include:

--Achieving 111 percent year-over-year revenue growth, making 2004 the third consecutive year in which Crossbeam more than doubled its revenue

--Signing on more than 200 new customers, including major enterprises such as British Petroleum, United Airlines and Qualcomm, bringing Crossbeam's total customer base to 455 customers

--Increasing international sales, with overseas sales accounting for 50 percent of revenue

--Earning 60 percent of its revenue from service providers, including two of the top three RBOCs, five of the top 10 PTTs in Europe and five of the top 10 wireless operators in Europe

"From powering an RBOC's managed firewall service to protecting the transactions of a multi-national financial services powerhouse, global blue chip companies increasingly turn to Crossbeam as the trusted source for large, integrated security solutions," said Peter George, president and CEO of Crossbeam Systems. "As we look to build on our momentum in 2005, Art's security expertise and experience in taking successful growth companies to market leaders will be a real asset for expanding Crossbeam's business."

Over the last 10 years, Mr. Coviello has helped RSA Security become one of the leaders in information security, growing its revenue 10-fold in eight years. On the board of directors, he will advise Crossbeam as the company looks to build similar revenue growth.

"Crossbeam provides tremendous value to enterprises and service providers by allowing them to improve network security while lowering their capital and operational costs through network consolidation," said Mr. Coviello. "I look forward to joining Crossbeam's board of directors and helping the company extend its reach into new markets."

Mr. Coviello joined RSA Security in 1995, helping the company increase revenue from $25 million in 1995 to more than $305 million in 2004. Before joining RSA Security, he served as chief operating officer for CrossComm Corporation, an internetworking vendor. He has also held various finance and management positions in graphics software and semiconductor equipment companies. In addition, he has served on numerous outside boards of directors. He began his career at Deloitte & Touche as a CPA, and graduated magna cum laude from the University of Massachusetts.
