ManTech on Wednesday announced a $668 million GSA FEDSIM award to support the Department of Homeland Security’s Continuous Diagnostics and Mitigation (CDM) Dynamic and Evolving Federal Enterprise Network Defense (DEFEND) program.

Under the new six-year agreement, ManTech will serve as the prime contractor providing CDM capabilities and support to DHS and the 9 agencies in CDM Group E, strengthening their cybersecurity posture and improving their ability to rapidly respond to today’s rising threat of cyberattack.

CDM was launched in 2012 in a bid to protect the federal government from cyber vulnerabilities. On Tuesday, the House passed a bill sponsored by Rep. John Ratcliffe (R-Texas) to codify the CDM program and bring it into its second of four phases.

ManTech will support CDM efforts within the Department of Education (ED), Department of Housing and Urban Development (HUD), the HUD Office of Inspector General (HUD OIG), the Environmental Protection Agency (EPA), the Federal Deposit Insurance Corporation (FDIC), Nuclear Regulatory Commission (NRC), National Science Foundation (NSF), Securities and Exchange Commission (SEC), and Small Business Administration (SBA).

The objectives of the CDM DEFEND effort are to reduce agency threat surfaces, achieve advantageous cost and price discounts for tools and capabilities, and accelerate the implementation and adoption of the CDM program within participating agencies.

“ManTech has played a strategic role in the CDM program for over three years, supporting more than 65 agencies in both Phases 1 and 2, and we’re honored to continue supporting the CDM program’s critical role in defending federal networks,” said Kevin Phillips, ManTech president and CEO.

Other major contracts awarded by DHS for the CDM program include a $530 million contact granted to CGI Federal in July, partially focused on cloud protections, and a $621 million, six-year contract  to Booz Hamilton Allen earlier this year.
