Symantec Network Security 7160 Appliance Earns "NSS Approved" Award in Intrusion Prevention Group Test

Symantec's Intrusion Prevention Appliance Achieves Stellar Scores in Extensive Testing of Performance, Security Effectiveness and Usability

CUPERTINO, Calif. - August 2, 2005 - Symantec Corp. (NASDAQ: SYMC) today announced that the Symantec Network Security 7160 Series appliance achieved the highest out-of-the-box scores in security effectiveness and near 100-percent scores for its other key capabilities in an independent test of Intrusion Prevention Systems (IPS) by The NSS Group, the world's foremost independent security testing facility. As a result, Symantec's intrusion prevention appliance earned the globally recognized "NSS Approved" award, given only to products that successfully complete the exhaustive tests of performance, security and usability.

The Symantec Network Security 7160 intrusion prevention appliance was reviewed during the NSS IPS Group Test, an extensive side-by-side comparison that used more than 800 tests to evaluate the performance and reliability, security effectiveness and usability of leading Network IPS products. The tests also simulated extreme situations often seen in enterprise environments.

"The Symantec Network Security 7160 appliance delivers very high levels of performance with first-rate policy management, incident management, alert handling and reporting out of the box," said Bob Walder, director, The NSS Group Ltd. "Its signature recognition was excellent out of the box, handling our demanding false positives, false negative and evasion tests easily, and was the only product to score 100 percent resistance to false positives out of the box, crucial for not blocking legitimate traffic. Overall, the Symantec Network Security 7160 appliance should definitely be considered for large-scale IPS/IDS deployments."

Performance and Reliability - The Symantec Network Security 7160 continued to detect and block 100 percent of attacks while subjected to settings similar to an enterprise network under the most extreme conditions. According to the test, the Symantec Network Security 7160 appliance "performed consistently and completely reliably throughout our tests…Under eight hours of extended attack (comprising millions of exploits mixed with genuine traffic) it continued to block 100 percent of attack traffic, whilst passing 100 percent of legitimate traffic." The NSS Group confirmed Symantec's 1Gbps rating for this device under all normal conditions and commended its latency, stating that the appliance can be "deployed anywhere on a Gigabit network - either internally or at the perimeter." The appliance also demonstrated its enterprise viability by maintaining state on more than 1,000,000 concurrent connections.

Security Effectiveness - The Symantec Network Security 7160 appliance earned the highest out-of-the-box scores in security effectiveness, a category that includes attack detection and blocking, resistance to false positives and resilience against IPS evasion. Its innovative Intrusion Mitigation Unified Network Engine (IMUNE), coupled with Symantec's industry-leading threat intelligence and response capabilities helped the appliance achieve the only 100-percent score in attack detection and blocking, following an update. In addition, the Symantec Network Security 7160 appliance was the only solution to earn a 100-percent score for its resistance to false positives without an update and one of only two vendors to demonstrate perfect resistance to all evasion attempts, which are commonly used to bypass prevention and render an IPS useless. The NSS Group stated that the Symantec Network Security 7160 "achieved a clean sweep across the board in all our evasion tests."

Usability - The NSS Group underscored Symantec Network Security 7160's strength in policy management, alert handling and reporting capabilities. The NSS Group found its policy management to be "powerful, scalable and intuitive," and commended the advanced correlation capability for alleviating the burden of distinguishing the genuine alerts from the irrelevant. Further, The NSS Group found Symantec Network Security 7160's incident handling capabilities, which are crucial for enterprise deployments, to be "very impressive…The ability to handle large quantities of data are vital in a high-bandwidth system, especially when it is possible to include events from third-party sensors, and SNS acquits itself with honors in this area."

"The NSS IPS Group Test results validate the superior capabilities of Symantec Network Security 7100 Series, specifically the devices' ability to detect and block today's broad range of attacks while handling real-world Internet traffic at high 1Gbps rates with very low latency," said Sandeep Kumar, director of product management for Symantec Network Security solutions. "That's a necessary formula for intrusion prevention solutions to effectively protect enterprise networks."
