System One has named John Heneghan chief executive officer of government solutions, bringing in the executive who led ECS through four years of expansion in federal AI and cybersecurity work.
As head of the government services business, Heneghan will direct operations with a primary focus on expanding market share, scaling service offerings and strengthening strategic customer relationships, System One said Monday. He will work with the teams at Gap Solutions, KeyLogic and Quadel — companies that System One acquired — to extend the company’s reach across government.
“We are thrilled for John to join our team to lead our government business. He brings a proven record of success leading and accelerating company growth in the government market,” said President and Chief Operating Officer Greg Lignelli. “John understands our customers and where they are headed. He will mobilize teams and solutions to help our customers meet their mission objectives.”
Who Is John Heneghan?
Heneghan, a five-time Wash100 awardee, most recently served as a consulting transformation officer at Everforth, working on the company’s shift toward an artificial intelligence-led digital engineering model.
He was previously the president of ECS, the IT systems integrator now known as Everforth ECS, serving from January 2022 until February 2026, when Donnie Scott succeeded him.
During that tenure, the company expanded across federal AI, cyber defense, cloud mission environments and enterprise modernization. ECS has served as an AI interoperability integrator on the National Geospatial-Intelligence Agency’s Maven program since 2017 and won the potential $104.3 million Canyonlands contract from NGA in December 2025 to continue AI development work. A joint venture between ECS and Yakshna Solutions took a position on the Treasury Department’s $20 billion PROTECTS cybersecurity blanket purchase agreement in March 2025, and the company won a spot on the GSA OASIS+ vehicle that February.
Heneghan joined ECS in September 2017 as senior vice president leading enterprise solutions delivery for customers, including the U.S. Postal Service, FBI, the Department of Homeland Security, Health and Human Services, the Defense Information Systems Agency and the U.S. Army, becoming chief operating officer in 2021. Before that, he spent six years as a vice president at CGI Federal, overseeing a portfolio covering DHS, the Coast Guard and the Office of Personnel Management, and was executive vice president at SPS Consulting. He spent nine years at Stanley Associates, now a wholly owned subsidiary of CGI Federal, in program management, proposal and corporate development roles.
Heneghan holds a bachelor’s degree from the University of Maryland.
