McAfee, Inc. (nyse: MFE) is an antivirus software and computer security company headquartered in Santa Clara, California. It markets McAfee VirusScan and related security products and services, including the IntruShield, Entercept, and Foundstone brands.

History

The company was founded in 1987 as McAfee Associates, named for its founder John McAfee. Network Associates was formed in 1997 as a merger of McAfee Associates and Network General. In 2004, a major restructuring occurred. In the spring, the company sold its Magic Solutions business to Remedy, a subsidiary of BMC Software. In the summer of 2004, the company sold the Sniffer Technologies business to a venture capital backed firm named 'Network General' - the same name as the original owner of Sniffer Technologies. Also, the company changed its name back to McAfee to reflect its focus on security-related technologies.

Among other companies bought and sold by McAfee (formerly known as Network Associates) is Trusted Information Systems, which developed the Firewall Toolkit, which was the free software foundation for the commercial Gauntlet Firewall, which was later sold by McAfee to Secure Computing Corporation. Network Associates, as a result of brief ownership of TIS Labs/NAI Labs/Network Associates Laboratories/McAfee Research, was highly influential in the world of Open Source software, as that organization produced portions of the Linux, FreeBSD, and Darwin operating systems, and developed portions of the BIND name server software and SNMP version 3.

Leading up to the TIS Labs acquisition, McAfee had acquired Calgary, Alberta Canada-based FSA Corporation, which helped the company diversify its security offerings away from just client-based antivirus software by bringing on board its own network and desktop encryption technologies. The FSA team also oversaw the creation of a number of other technologies that were leading edge at the time, including firewall, file encryption, and public key infrastructure product lines. While those product lines had their own individual successes including PowerBroker, written by Dean Huxley and Dan Freedman and now sold by Symark Software), the growth of antivirus always outpaced the growth of the other security product lines. It is fair to say that the company remains best known for its antivirus and antispam product lines.

On June 9, 1998 Network Associates agreed to acquire Dr Solomon's Group P.L.C, the leading European manufacturer of Antivirus software, for $642 million in stock.

On April 2, 2003, McAfee acquired IntruVert Networks for $100 million. According to Network World, "IntruVert's technology focus is on intrusion-prevention, which entails not just detecting attacks, but blocking them. The IntruVert product line can be used as a passive intrusion-detection system, just watching and reporting, or it can be used in the intrusion-prevention mode of blocking a perceived attack."
