Arbor Networks Honored with ''Hot Companies'' Award.

LEXINGTON, Mass. -- Arbor Networks Kicks off 2006 with continued success

Arbor Networks, a leader in network security, announced today that it has been named one of Info Security Products Guide's "Hot Companies" winners for 2006. Selected from an industry analysis of more than 600 information security vendors around the world, Arbor Networks was one of only fifteen percent chosen for this prestigious honor based on the company's tremendous success in 2005.

"Great architecture and an effective threat response system that automatically updates against new and future attacks are possibly the best assurances any enterprises can ask for when seeking to protect their corporate networks," said Rick Justice, chief editor of Info Security Products Guide, which is published by Silicon Valley Communications. "Security products become obsolete in just a few days unless they are updated against newer threats and their architectures were designed to support zero-day threats. Arbor Networks takes Intrusion Prevention Systems (IPS) to the next level by ensuring that they continue to support their customers proactively and network-wide."

"We are delighted to be recognized by the Info Security Products Guide as one of the top companies in 2006," said Arbor Networks' Vice President of Marketing Tina Stewart. "This award recognizes our position as a leader in this space. Arbor Networks provides core-to-core network security and operational performance for global business networks, from the service provider cloud to the enterprise core."

Arbor Networks provides the most widely-used security appliances for the prevention of distributed denial-of-service attacks, fast-spreading worms and internal network misuse. The Arbor Peakflow platform is used by Fortune 1000 companies and by more than 70 percent of the world's service providers, including AT&T, British Telecom, EarthLink, NTT Com and Verizon Business.

In 2005, Arbor Networks was recognized for its financial growth and innovative technology. Inc. Magazine named Arbor Networks No. 9 to its Inc. 500 list of fastest-growing private companies; Red Herring named Arbor Networks to its "Top Ten Companies to Watch" list; and Deloitte & Touche named Arbor a "Rising Star" in the Deloitte Fast 50 Private Companies to Watch. In addition, American Water, the third largest water supplier in the United States, was named to the InfoWorld 100 list for protecting its network using Arbor Peakflow X.
