TSA Expands Pre-Check Program

TSA's known-traveler program is being expanded to Las Vegas' McCarran International Airport.

The program, known as Pre-Check, allows passengers to volunteer information to the agency in exchange for the possibility of receiving expedited screening. TSA has been testing the program at airports in Dallas, Tex., Miami, Detroit, Boston and Atlanta.

The agency said Wednesday it would extend the ability to sign up for Pre-Check, which is part of its move to a "risk-based" security system, to passengers flying out of Las Vegas.

“I am encouraged by the positive passenger feedback and early results from this risk-based security initiative, and look forward to working with our airline and airport partners as we continue expanding and testing this concept,” TSA Administrator John Pistole said in a statement.

“This system enables our officers to expedite the screening process for passengers we know the most about, while better focusing their efforts on higher-risk and unknown passengers," he continued. "As we continue to implement a system with multiple layers of security to keep the traveling public safe, we are dedicated to providing the most effective security in the most efficient way.”

ON DEMAND: Business-impacting events such as severe weather, man-made disasters, and supply chain disruption are increasing in frequency and making impacts around the globe.

In today's rapidly evolving security landscape, organizations face an ever-growing array of disruptive events, security threats and risks. Traditional reactive approaches to security intelligence often leave businesses vulnerable and ill-prepared to anticipate and mitigate emerging threats that could impact the safety of their people, facilities or operations.
