Layered Antivirus Products Offer Greater Protection Against Blended Threats, Says IDC

FRAMINGHAM, MA – OCTOBER 10, 2002 – As computer viruses and malicious code become increasingly virulent and difficult to detect, corporations will need to implement more flexible and comprehensive security solutions to protect their networks and information. Layered security, using a combination of desktop antivirus, server antivirus (e.g., email) and content filtering applications, yields greater protection against network attacks. By tightly linking these applications, IDC believes that a layered security approach will create a defense stronger than its individual parts working separately.


"Recent network attacks, such as Code Red and Nimda, provide clear evidence that hackers and crackers are becoming much more sophisticated in their abilities," said Brian Burke, senior research analyst for IDC's Internet Security Software service. "Blended threats are specifically designed to get past point-solution security products. The best way to provide overall protection for a company's network is through an integrated approach utilizing layered security applications. As blended threats gain more harmful payloads, a layered approach will become even more critical."

IDC expects that integrated layered security solutions will become more widely available in 2003 and will help drive significant growth in the security market. The worldwide antivirus (AV) software market reached $1.67 billion in revenues in 2001, according to IDC, representing 19% growth over 2000 revenues. IDC believes that managed services for antivirus protection will enjoy a compound annual growth rate (CAGR) of 73% over the next four years, growing from $42 million in 2000 to approximately $647 million in 2006. Security solutions for server/gateway platforms will also exhibit strong growth, with a 24% CAGR from 2001 to 2006 and revenues increasing from $508 million in 2001 to nearly $1.5 billion in 2006. This category will represent the most dominant share of the market in 2006, with 44%.
