FAIRFAX, VA, April 29, 2020 -?CGI (NYSE: GIB) (TSX: GIB.A) announced that it has been awarded a six-year, US$267 million task order to provide cybersecurity consulting services under the U.S. Department of Homeland Security's (DHS) Continuous Diagnostics and Mitigation (CDM) Program for CDM's Dynamic and Evolving Federal Enterprise Network Defense (DEFEND) Group F Federal agencies. The contract was awarded via the U.S. General Services Administration's Alliant 2 government-wide acquisition contract through an acquisition conducted by GSA FEDSIM.

CGI will provide DHS's Cybersecurity and Infrastructure Security Agency?(CISA) with a shared services platform to deliver CDM cybersecurity capabilities to over 75 non-Chief Financial Officer (CFO) Act agencies. Additionally, CGI will provide a shared services catalog (SSC) of capabilities and services that meet CDM program goals. The SSC will grow and evolve with the threat and technology landscape and will allow CGI to develop innovative solutions that prioritize cloud native and hosted service solutions.

"CGI has played a strategic role and been a trusted partner to CISA, for the past four years, though our work on Credential Management and DEFEND Group C," said CGI Senior Vice-President Stephanie Mango. "In partnership with CISA we have worked across many agencies to identify and address cybersecurity challenges. We look forward to continuing our support of this critical cross-agency initiative and leveraging our wealth of cybersecurity and shared services expertise to help DHS achieve its ultimate objectives."?

CGI's contributions to the CDM program began in 2016 with a contract award for identity management services through the Credential Management Task Order, providing design and implementation services to 26 Federal agencies. CGI provided agencies with tools, sensors and services to implement elements of credential management to strengthen policies and practices for all authorized users at participating agencies. In 2018, CGI was awarded the DEFEND Group C contract award – a six-year task order requiring new cybersecurity capabilities via standardized security stacks for a set of seven large agencies. Through the Group C contract, CGI provides those agencies improved visibility and insight into their cyber risks with a centralized view across the government infrastructure. The Group F contract leverages the company's experience with the CDM Program. The shared services platform CGI delivers will provide non-CFO Act agencies?access to the same cybersecurity tools as their larger, cabinet-level counterparts.
