The global market for intrusion detection and prevention systems reached $382m (£241.6m) in 2002, and is forecast to quadruple to $1.6bn (£1bn) by 2006, according researchers.
Infonetics Research's forecast report, Intrusion Detection and Prevention Products, said that the security market is booming as intrusion detection becomes a must-have technology.
"Intrusion detection and prevention is making the transition from niche security technology to core network infrastructure, similar to the transition firewalls made between 1995 and 2001," explained Jeff Wilson, executive director of Infonetics Research, in a statement.
"Organisations of all sizes are looking for the next step in perimeter security, and network intrusion prevention will be the primary driver for the explosive growth we forecast through 2006."
Infonetics said its research showed that, for the last quarter of 2002, the race for market share was tight, with Internet Security Systems on top at 23 per cent share and Cisco close behind at 18 per cent.
But the analyst predicted that the picture is likely to change significantly over the next two years, with the hardware market poised for dramatic growth.
Currently the study shows that North America accounts for 62 per cent of intrusion detection and prevention product revenue, with Europe, Middle East and Africa sales scoring 19 per cent.
