Anti-virus software company McAfee Monday said it is buying Foundstone, which makes software for detecting and managing software vulnerabilities, for $86 million in cash.

The acquisition will add Foundstone's line of vulnerability management software to McAfee's growing list of security products. McAfee plans to combine Foundstone's technology for spotting and remediating software vulnerabilities with its intrusion detection and security policy management products, allowing companies to identify and shield high-priority computer assets from attack.

As part of the deal, Foundstone's professional services group will become part of McAfee's services team, McAfee said.

McAfee's purchase of Foundstone, in Mission Viejo, Calif., follows moves in the last year to focus its product offerings and bolster its standing in the intrusion detection and prevention market. In April 2003, McAfee, formerly Network Associates, paid $220 million to purchase two companies: IntruVert Networks and Entercept Security Technologies, both of San Jose.

The acquisitions gave McAfee, of Santa Clara, a jump start in detecting network-based attacks, IntruVert's specialty, and attacks targeted at network servers, or "hosts."

McAfee in recent months has also shed products and business units. In December 2003, the company announced the sale of its Magic help desk and management software division to BMC, an enterprise management products maker, for $47 million. In April, the company said it was selling its Sniffer family of network management products for $275 million in cash to an investment group including Silver Lake Partners and Texas Pacific Group, which relaunched the product under the auspices of a reconstituted Network General.

McAfee will focus initially on getting Foundstone's technology to recognize and interact with the IntruVert and Entercept technologies, as well as McAfee's VirusScan 8, said Vince Rossi, senior vice president of product management at McAfee.

The goal is to give customers the ability to assess their exposure to Internet and network-borne threats using a constantly updated threat profile provided by McAfee's other products. With detailed information on which of their computer assets are the most exposed to threats, IT departments can focus their efforts on dealing with the biggest threats to their most critical assets, saving time and effort, he said.
