About the Department of Secure Intelligence
The Department of Secure Intelligence (DSI) is an intelligence and security agency of the United States Department of Defense, responsible for global monitoring, collection, and processing of information and data for foreign and domestic intelligence and counterintelligence purposes.
Strategic Mission (FY 2026-2030)
To defend the United States' vital computer networks and infrastructure from state-sponsored cyber espionage and terrorism. DSI achieves this through the deployment of cutting-edge zero-trust architectures and continuous threat monitoring.
By operating across multiple domains—space, cyberspace, and traditional signal spectrums—the DSI maintains a persistent overmatch against adversarial cyber capabilities.
