Check Point primarily concentrates on firewalls, which is server-side software that monitors incoming and outgoing network traffic and prevents malicious intrusions. Zone Labs produces similar software for desktops and notebooks. The Zone Labs software can also help prevent PCs from becoming drones that can be used by attackers to launch assaults on other systems.
Working together, the two types of software can further help corporations defend themselves against attacks, the companies said.
"The biggest opportunity we have is bringing security to every desktop," Check Point chief executive Gil Shwed said in a statement.
Check Point also hopes the acquisition will help it better position itself competitively through diversification. Security companies previously had only specialised in a few products. Now most are trying to sell a broad array of products that will work in concert. Symantec for instance, bought two software companies specialising in management tools that, over time, will make it easier for customers to update their security systems.
Shwed, in fact, said that next quarter the company will come out with new products for beefing up Web security and security within companies.
Zone Labs has approximately 25 million users of its ZoneAlarm application, many of which use the free version of the product. The company, however, also has a corporate version that comes with tools that let information technology employees manage desktops remotely. Zone Labs also sells security software for instant messaging, which it bought earlier from IMSecure.
Check Point will pay $113m (£64.7m) in cash and $92m in stock for Zone Labs.
