Homeland Protection

Developing technology to keep the nation safe

A vital mission of the U.S. government is to secure the nation from the many threats it faces. We support this mission by assessing, prototyping, and deploying innovative technology that helps reduce the nation's vulnerability to terrorism, secure transportation systems, and protect critical infrastructure.

The ERSA system uses cameras to track aircraft flying too close to the capital’s no-fly zone.

Homeland Protection Groups

We apply artificial intelligence (AI) and machine learning technologies and develop prototypes to meet critical national security needs. Our technology portfolio uses AI for a range of applications, from augmenting human capability to enabling autonomous systems.
