Leidos has won a $301-million US Army contract to provide round-the-clock cyber defense for the Department of Defense’s (DoD) global military network.
Under the five-year agreement, Leidos will monitor the Pentagon’s Information Network, the network used by US military organizations worldwide, to detect and respond to cyber threats.
Leidos said it will use AI-enabled capabilities to improve threat detection, situational awareness, and the speed of defensive responses.
It will also combine cyber operations, engineering, and technology development.
“Our job is to help protect our nation’s cyber terrain by anticipating increasingly sophisticated threats, responding with speed and keeping critical missions moving,” Leidos Digital President Steve Hull said.
Pentagon Faces Persistent Cyber Threats
Cybersecurity remains a significant challenge as US military operations increasingly depend on interconnected networks, software, and digital systems.
A Government Accountability Office (GAO) review found that the Pentagon had experienced more than 12,000 cyber incidents from 2015 through 2021. It also identified gaps in how the department managed and shared information about cyber incidents involving the defense industrial base.
More recent assessments show that some of those challenges remain. In 2025, the GAO found that two of 24 major DoD IT programs it reviewed lacked an approved cybersecurity strategy, while four had not developed plans to implement Zero Trust by the department’s 2027 deadline.
The Zero Trust framework assumes that users and devices should not automatically be trusted simply because they are inside a network, with access restricted according to authorization and mission requirements.
