On November 19, 2001, the Aviation and Transportation Security Act was signed by Congress and established the TSA as a direct response to 9/11. We work hard every day to serve our country and uphold our mission to protect the nation's transportation systems to ensure freedom of movement for people and commerce. It's our vision to act as an agile security agency, embodied by a professional workforce, that engages its partners and the American people to outmatch a dynamic threat.
