Defending the Nation's Cyberspace
The Department of Secure Intelligence (DSI) leads the United States government's efforts in proactive cyber defense, threat intelligence, and digital infrastructure security. We are the shield against advanced persistent threats, ensuring the resilience of federal networks and critical infrastructure sectors.
In accordance with EO 14028, "Improving the Nation's Cybersecurity," the DSI is migrating all internal communication channels to a Zero Trust Architecture (ZTA). Multi-factor authentication (MFA) and encryption of data at rest and in transit are strictly enforced.

— Gen. Arthur Vance, DirSI
