Symantec ManHunt Receives NSS Approved Award During Gigabit Intrusion Detection Test

The NSS Group Rates Symantec ManHunt as a True Gigabit IDS Solution

CUPERTINO, Calif. - August 11, 2003 - Symantec Corp. (NASDAQ: SYMC), the world leader in Internet security, today announced that Symantec ManHunt network intrusion detection system achieved the recognized NSS Approved award in an independent test of Gigabit Intrusion Detection Systems (IDS) by The NSS Group, Europe's leading network and security testing organization.

The NSS Group's test evaluated the attack detection accuracy, performance, attack evasion, stateful operation and management of all participating products in real-world conditions.

Symantec ManHunt's results in stateful operation were flawless; it was the only product to track 1 million real connections easily using the default settings out of the box, with no tuning required.

In the Gigabit performance tests, Symantec ManHunt demonstrated excellent levels of performance across the board. The product achieved 100 percent detection rates at all load levels in all "real world" traffic tests, and was capable of monitoring fully utilized Gigabit networks.

"ManHunt manages to combine very high levels of performance with an excellent correlation engine and good reporting and analysis capabilities across multiple sensors," said Bob Walder, Director The NSS Group Ltd. "The ability to correlate data from third-party IDS and firewall products makes it particularly attractive in large enterprise deployments, whilst the reduction in false positives and enhanced protection against zero-day exploits offered by the protocol anomaly detection architecture makes it attractive in any environment."

Symantec ManHunt's unique hybrid detection capabilities excelled during the test, with the report noting this as a trend for future Network IDS products. The strength of combining multiple detection techniques within the product was highlighted in the detection tests with Symantec ManHunt achieving an excellent custom Attack Recognition Rating (ARR) of 96 percent. In addition, Symantec ManHunt's protocol anomaly detection, which detects zero-day attacks without the need for signatures updates, showed complete resistance to false positives generated during the test, achieving a perfect score.

The test also underlined Symantec ManHunt's strength in its incident management capabilities. For most organizations, IDS products generate mass volumes of data, which requires both security expertise and time to sort through to find the relevant information, assess the problem, take action and merge data for reporting. The NSS Group commends Symantec ManHunt's correlation engine for its ability to combine multiple events from multiple sensors into single incidents, alleviating the burden of distinguishing the genuine alerts from the irrelevant.

"Symantec ManHunt solves the inherent problems seen in traditional IDS products - false positives, data overload, ineffective countermeasures and poor management," said Sandeep Kumar, director of product management at Symantec. "We are very pleased with the results of The NSS Group's IDS test, and remain committed to providing our customers with a best-of-breed, true Gigabit IDS solution."

Overall, The NSS Group endorsed Symantec ManHunt as having accomplished perfect or near-perfect detection capabilities at all levels and all types of traffic in the tests. It also recommended Symantec ManHunt for customers with a genuine need to monitor Gigabit levels of traffic with a single sensor and zero risk of dropped packets.
