About TSA

The Transportation Security Administration (TSA) is an essential component of the U.S. Department of Homeland Security, tasked with safeguarding the country’s transportation systems. Established in response to the September 11, 2001 terrorist attacks, the TSA enhances security protocols across various modes of transportation, with a particular focus on aviation.

The agency is responsible for the security screening of both passengers and baggage at over 450 U.S. airports and employs a diverse workforce of over 47,000 individuals. This workforce includes Transportation Security Officers, Federal Air Marshals, explosives experts, canine teams, and other security personnel dedicated to preventing aircraft hijackings and ensuring safe travel.

Beyond aviation, the TSA also plays a critical role in the security of other transportation networks, including rail, mass transit, highways, pipelines, and ports. The TSA’s approach to security is both risk-based and layered, integrating intelligence data, advanced screening technologies, and variable security measures to adapt to emerging threats.

Programs such as TSA PreCheck exemplify the agency’s strategy to streamline screening processes for pre-approved, low-risk travelers at more than 200 airports. Initially part of the Department of Transportation, the TSA was transitioned to the Department of Homeland Security in 2003.

Despite facing scrutiny over its screening methods and the treatment of passengers, the TSA remains focused on its mission to mitigate threats to transportation security.
