Gartner Dataquest Report Says Symantec Continues to Gain Market Share as World's Top Security Software Provider

CUPERTINO, Calif. - July 24, 2003 - Symantec Corp. (Nasdaq: SYMC) today announced that a new Gartner Dataquest report reflects Symantec's continued position as the world's leading security software provider based on new license revenue in 2002. According to the "Worldwide 2002 Security Software Market and Vendor Shares" report, Symantec's market share of the overall worldwide security industry increased from 15 percent in 2001 to 19 percent in 2002, leading the list of the world's top 25 security software vendors.

The growth of Symantec's market share was underscored by the expansion of its lead over the second-place company from less than five percentage points in 2001 to more than nine percentage points in 2002. According to the report, Symantec's year-over-year growth rate of 40 percent more than quadrupled the growth rate of the security software industry as a whole, which came in at nine percent. Overall performance was based on two separate segments covered in the report: security infrastructure software and security administration software.

Symantec retained the top position for the third straight year in the security infrastructure software segment. According to Gartner Dataquest, the segment includes antivirus, encryption, intrusion detection, network security (firewall and virtual private network), web content filtering and security event and performance management software.

Symantec's compound annual growth rate of 39 percent for the period of 2000 to 2002 tripled the industry rate of 13 percent.

"The most significant aspect of this report shows that Symantec's market share continues to grow at a steady rate and outpace the industry as a whole," said John Schwarz, president and chief operating officer, Symantec. "Blended attacks such as SQL Slammer and Bugbear will become more frequent and severe as the time between vulnerability identification and exploitation becomes progressively shorter and shorter. To ward off future cyber threats, customers are adopting an integrated set of security solution that operate at the gateway, server and client levels. Symantec is the only provider that offers a complete integrated alerting, internet posting, customer response and service management solution for the enterprise user."

According to the report, Symantec placed tenth in the field of 24 with the offering of only one product, Enterprise Security Manager, and experienced a strong growth rate of 27 percent from 2001 to 2002.
