In an effort to improve its cyber-protection technology, Waltham-based Raytheon has reached agreement with private-equity firm Vista Equity Partners LLC to acquire an 80 percent share of Websense Inc. for $1.9 billion. Vista acquired Websense two years ago for about $990 million.
Raytheon plans to integrate Websense into its existing Raytheon Cyber Products unit and operate the new division with Websense incumbent CEO John McCormack at the helm.
In addition to contributing the $400 million cyber products unit, Raytheon will infuse $1.6 billion in cash, $600 million in the form of a loan. For its 20 percent stake, Vista will contribute $335 million to the venture.
Websense’s Triton platform, which allows companies to adapt and respond to future cyber attacks, is said to be what particularly appealed to Raytheon.
In November, Raytheon spent $420 million to bolster its intelligence business by acquiring surveillance and cybersecurity company Blackbird Technologies.
