Symantec's First Line of Intrusion Prevention Appliances Receives "CRN Test Center Recommended" Designation

CUPERTINO, Calif. - Aug. 10, 2004 - Symantec Corp. (NASDAQ: SYMC), the global leader in information security, today announced that CRN, a CMP United Business Media publication, has awarded Symantec Network Security 7100 Series the highest possible scores for its comprehensive review of the solution.

CRN reviewed the Symantec Network Security 7120 appliance, one of three models in the Symantec Network Security 7100 Series, and awarded the solution with five out of five stars for both the technical merit and Symantec's channel program. As a result, Symantec Network Security 7100 Series earned the "CRN Test Center Recommended" designation, an honor bestowed only solutions with an average of the two ratings equaling four stars or greater.

"We are honored to have Symantec Network Security 7100 Series recognized by CRN," said Enrique Salem, senior vice president of network and gateway solutions, Symantec. "The results of this comprehensive review confirm that Symantec's first line of intrusion prevention appliances provide a high level of robust protection against today's blended threats while also offering real benefits to our channel partners."

Appearing in the CRN August 2, 2004 issue, the review praised the Symantec Network Security 7100 Series on several of its key technologies and capabilities.

According to the review, "The [Symantec Network Security 7100 Series] offers several fully scalable appliances with throughput ranges from 50 Mbps to 2 Gbps that can meet the security needs of any business, no matter the size."

In addition, the review singled out the product's Intrusion Mitigation Unified Network Engine (IMUNE™), which protects against known and unknown attacks: "Several technological advances help to make the 7100 series unique in the security appliance market…Symantec's network threat mitigation architecture combines anomaly, signature, statistical and vulnerability detection techniques to secure networks from known and unknown attacks. In other words, the 7100 series can prevent attacks and outbreaks even if no virus or anomaly signatures exist."
