McAfee has completed the acquisition of Secure Computing in a deal worth $462m.
Secure Computing brings with it more than 22,000 customers in 106 countries.
McAfee said in a statement that Dan Ryan, president and chief executive officer of Secure Computing, will lead McAfee's Network Security product business unit and will report to Dave DeWalt, chief executive officer and president.
DeWalt said, "McAfee's goal is to provide intelligent security that protects from every angle, including the endpoint, the network and all points in between."
The acquisition enables McAfee to combine its end-point security and network intrusion prevention technology with Secure Computing's web and email security capabilities, he said.
McAfee also plans to use Secure Computing's Trusted Source technology to expand intelligent "in-the-cloud" security services for an additional layer of defence.
