The Department of Homeland Security (DHS) has reaffirmed its decision in fall 2015 to award a $1 billion contract to Raytheon [RTN] to provide support for the division responsible for the cyber security system that helps protect federal civilian networks, DHS and the company said statements.

Raytheon won the Development, Operations and Services (DOMino) contract in September 2015 to provide support to the DHS National Cybersecurity Protection System (NCPS), which is better known as EINSTEIN. However, in early October at least one losing bidder, Northrop Grumman [NOC], protested the award.

General Dynamics [GD] was the original contractor supporting EINSTEIN, a platform that protects more than 100 federal civilian government agencies. The DOMino contract is new.

Raytheon in its statement said that “After completing corrective actions stemming from the GAO protest of the DOMino award decision, the U.S. Department of Homeland Security has reaffirmed the selection of Raytheon Company.”

The contract is for five years and some orders can be extended for two more years. Raytheon will provide services to operate and maintain existing EINSTEIN capabilities and to design and develop new cyber security capabilities.

Senate appropriators in their version of the FY ’17 DHS spending bill recommend $480.5 million fore the NCPS. The funding will allow the DHS National Protection and Programs Division, which is responsible for NCPS, to continue deploying EINSTEIN’s new intrusion prevention capabilities, as well as information sharing and analytics across the federal civilian government.
