"All of our data protection and rights management customers will benefit from today's announcement, whether they are commercial, critical infrastructure or government enterprises," Dave Hansen, who was appointed president and CEO on Monday, said in a statement. "It will enable us to continue to sharpen our focus and extend our leadership in the explosive growth markets of data protection for cloud and virtual environments, and security from the cloud."
Raytheon, a $25 billion defense company based in Waltham, Mass., said it acquired the SafeNet business to help meet growing demand for protected, encrypted classified data. The acquired business will complement Raytheon communications systems that allow the U.S. military to transmit classified voice and data traffic securely, the company said in a statement.
