The Transportation Security Administration was created to strengthen the security of the nation’s transportation systems while ensuring the freedom of movement for people and commerce.
In response to both 9/11 and evolving threats, and with the help and support of Congress, DHS has significantly adapted and enhanced its ability to detect threats through a multi-layered, risk-based system.
Securing the global supply chain, while ensuring its smooth functioning, is essential to our national security and economic prosperity.
Since the Department's creation, we have worked to secure all modes of transportation, land, air and sea.
