Win marks third consecutive year Heneghan has been recognized as “executive of consequence”

FAIRFAX, Va. — Feb. 22, 2024 — ECS, a leader in advanced technology, science, and engineering solutions and an ASGN (NYSE: ASGN) brand, announced today that President John Heneghan has been recognized as a 2024 Wash100 Award winner by Executive Mosaic, an international leadership organization and media company. The annual Wash100 list honors 100 “executives of consequence,” deemed among the most influential private and public sector leaders in the government contracting industry. This marks the third consecutive year that Heneghan has been recognized on the list.

Heneghan assumed the role of ECS president in 2022. He earned this year’s award as the company ramped up its pursuit of high-value strategic deals, delivered innovative and differentiated solutions in AI, cybersecurity, and IT operations, and expanded employee engagement and professional development programs.

“I’m proud to be named to the Wash100 list once again, because it reflects the value of the work we do and the impact our teams make on government missions,” said Heneghan. “Now, more than ever, collaboration, information sharing, and continuous learning are vital for federal organizations, and partners like ECS can play a key role. We’re looking forward to advancing our nation’s top technology priorities in 2024.”

Highlights from the previous year under Heneghan’s leadership include:

In 2023, ECS increased its focus on technological innovation and continued expanding its offerings to include ECS’ cyber analytics solution set, including:

  • ECS Pathfinder, which leverages AI/ML to proactively mitigate cyber risk.
  • Digital transformation road mapping tools that help customers develop and execute their transformation plans.
  • Forward-deployed mission collaboration platforms.
  • Autonomous and open-source AI platforms supporting intelligence missions.
  • Elite ServiceNow partnership, including being the first to migrate a customer to the IL-5 compliant ServiceNow National Security Cloud (NSC).

ECS also re-committed to creating an environment that attracts and engages top professional and technical talent, enhancing career development and leadership programs and expanding employee resource group (ERG) participation.

“John has distinguished himself in short order by recruiting and announcing key enhancements to the ECS management team as well as his pursuit of cyber protection, AI enhancement, machine learning, and digital transformation contracts,” said Jim Garrettson, chief executive officer of Executive Mosaic. “He has a well-earned reputation for positivity and an ability to build consensus among his senior team.”
