In their biggest acquisition to date, McAfee has announced plans to buy Secure Computing for $465 million. The deal will help round out McAfee’s security offerings, adding specialized equipment that keeps hackers from breaking into computer networks. This will vault the #2 rated computer security company further into the protection of business networks as well as boost the number of companies that use its services. “The market is moving toward bigger vendors with broader suites. That just means more dollars for McAfee,” McAfee Chief Executive DeWalt said. “That is why we are expanding the portfolio.” Secure Computing began in 1984 developing technology to protect computer systems at the U.S. National Security Agency. It was spun off as an independent company in 1989.
