The Department of Defense is building on its endpoint security effort with a potential $163 million task order to CSRA Inc. [CSRA] to integrate cyber management capabilities for the department’s Defense Information Systems Agency (DISA).

Under the deal, announced Wednesday, CSRA will work with Microsoft [MSFT] and McAfee to manage security tools for DISA’s Endpoint Security Solution (ESS) Integrator Support (IS) program.CSRA logo

The task order contains a one-year base period, with four one-year follow-up options.

“CSRA leads the industry as the top partner for the U.S. military through cutting-edge cyber services, training, and cloud integration. This award further solidifies our relationship with DISA, and we look forward to supporting its mission for years to come,” said Ken Deutsch, head of the company’s defense group, in a statement.

CSRA will work with McAfee to develop hardening and containment solutions for the Microsoft cyber security software utilized by DISA’s endpoint program.

“We look forward to working with DISA and CSRA to showcase a best-in-class approach to cybersecurity and endpoint protection. DISA is leading the way in its defense-in-depth approach and Microsoft’s technologies will help to ensure a no-compromises approach to DISA and CRSA’s cyber efforts,” said Gerald Robinson, general manager of Microsoft’s DoD Enterprise Services organization.

DISA has tasked CSRA with developing capabilities that allow the DoD Information Network to remain operable while portions of the system may be experiencing an attack. CSRA will integrate endpoint technologies to isolate and suppress cyber attacks in real-time, while still allowing network functionality.

The task order also calls for CSRA to provide closure for endpoint security capability gaps, build interoperability across the DoD security architecture and shorten implementation timelines for new capabilities.

“We are proud to continue our work supporting DISA and providing the best next-generation technology for our warfighters,” said Deutsch.

This latest deal follows an earlier $498 million contract from in June to CSRA to support DISA’s milCloud 2.0 phase one (Defense Daily, June 27).
