VPNs & Firewalls Lead Security Market

Despite the growing popularity of all-in-one security devices, two distinct product areas are driving most security revenue, according to the latest Infonetics Research Inc. "Network Security Appliances and Software Report."

In the second quarter of this year, VPNs (virtual private networks) and firewall hardware and software accounted for 78 percent of the $1 billion spent on security products, says the analyst firm. Intrusion detection systems (IDSs) and intrusion prevention systems (IPSs, duh) made up 14 percent, and gateway antivirus products accounted for the remaining 8 percent.

VPNs have certainly staked their claim in enterprise data centers recently. Last year, a Heavy Reading report identified Secure Sockets Layer (SSL) VPNs as one of the hottest parts of the technology sector (see Heavy Reading Analyzes SSL VPNs).

This trend is set to continue over coming years, at least according to Infonetics. VPN and firewall revenues are set to grow from $2.9 billion in 2004 to $4.7 billion in 2008. Revenue from gateway antivirus products is set to rise from $200 million to $700 million between 2004 and 2008. IDS and IPS technologies, however, will grow from $500 million to $1 billion over the same period.
