Bucking economic trends, the global security software market saw a 19 percent growth in revenue last year — totaling $13.5 billion, according to a Gartner report released this week. One of the major reasons for the rise was an increased interest in appliance products for email and web security and security and event management. Key drivers for purchases were data protection against targeted attacks, privacy and compliance. Symantec remains the top revenue producing company, but smaller vendors gradually are gaining market share. — DK
