Leidos is an American technology and engineering company that provides services and solutions to government and commercial customers, with a strong focus on national security, defense, intelligence, and civil government markets. The company delivers systems integration, engineering, cybersecurity, software development, data analytics, cloud migration and managed IT services, as well as mission support for complex programs. Leidos’ work spans areas such as C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance), secure communications, sensors and systems engineering, and health IT solutions for public-sector healthcare programs.
Leidos traces its corporate roots to Science Applications International Corporation (SAIC) and emerged as an independent, publicly traded company following a corporate separation in 2013. Since that reorganization the firm has continued to expand its capabilities to address evolving defense, intelligence and civil requirements, applying research and engineering to large-scale system deployments and program sustainment. It supports a broad range of mission types from system design and integration to operations, maintenance and modernization of legacy infrastructure.
The company primarily serves U.S. federal government agencies — including defense and intelligence customers — while also supporting allied governments and commercial clients worldwide. Its offerings are delivered through a combination of in-house technical teams, program management offices and partnerships, and the firm emphasizes secure, scalable solutions intended to support long-term mission outcomes. Leidos is governed by a board of directors and an executive management team; up-to-date leadership and corporate information are available through the company’s public disclosures.
