Leidos (NYSE: LDOS) demonstrated its Cyber and Electromagnetic Activities Resiliency System, known as CRS, during the Valiant Shield 2026 military exercise held June 22 to July 2 in Guam, according to a company press release.

During the joint field training exercise, CRS detected simulated cyber intrusions and identified unusual activities across tactical platforms and networks. Valiant Shield is a U.S. military exercise in the Indo-Pacific that brings together U.S. and partner nation forces across air, land, sea, space, and cyber domains.

"Cyber resilience is now essential to military readiness," said Jason O'Connor, president of Leidos Intelligence. "Commanders need to know when cyber activity could put the mission at risk. Valiant Shield gave us the opportunity to show that CRS can provide that awareness in realistic field conditions and help warfighters stay focused on the mission."

CRS is designed for military environments where standard cybersecurity tools may have limited visibility. The system monitors mission equipment and connected technologies for signs of unusual cyber activity across tactical platforms and networks.

Leidos, headquartered in Reston, Virginia, reported annual revenues of approximately $17.2 billion for the fiscal year ended January 2, 2026, and employs approximately 50,000 people globally.
