SAN FRANCISCO--(BUSINESS WIRE)--Feb. 24, 2004

Awarded Top Ranking for Enabling Companies to Proactively Combat Worms, Zero-day Threats and Internal Network Misuse/Abuse

Arbor Networks(TM), the leading provider of network integrity systems, today announced that its enterprise solution, Peakflow X, has captured a coveted "Tester's Choice" in a Secure Enterprise Magazine review of Network Anomaly Detection products. Highlighting the best-in-class caliber of the product, the review stated that, "Peakflow X is one of the most interesting boxes we've had the pleasure of test-driving in a long while."

Proven to meet the demands of the largest enterprise networks, Peakflow X provides comprehensive, real-time situational awareness of activity across the entire network. Only with this network-wide perspective can network operators effectively detect internal threats and intelligently assign security policy without disrupting the business.

In a head-to-head review that included products from vendors such as Lancope and Q1 Labs, Arbor's Peakflow X earned Secure Enterprise's prestigious distinction because its "solid analysis engine and stellar management features," did a superior job of informing operators of "what's happening on our network now." During the evaluation - in which Peakflow X was used to halt a major worm outbreak - reviewers also cited the product's unique ability to handle enterprise network deployment challenges such as complicated routing and accurate baselining of database, file sharing, and proprietary application protocols.

"We are very pleased that the successful adoption of Peakflow X by Fortune 100 companies and the Department of Defense has been validated by this prestigious honor," said Thomas Arthur, CEO and president of Arbor Networks. "With the relentless rise of zero-day threats - such as the recent MyDoom worm - we have answered customer demand for a better approach to securing enterprise networks. Peakflow X's comprehensive, real-time comparison of actual host traffic to normal host traffic successfully addresses internal network security by detecting and mitigating zero-day worms, intelligently segmenting networks, and resolving user misuse and abuse. We're honored to receive this recognition from Secure Enterprise."
