Experts in all aspects of aviation security

CAS offers a wide array of services to meet the complex security needs of the aviation industry. CAS has the extensive experience and proven performance providing security guard and screening services needed to meet the complex demands of the aviation industry nationwide.


CAS created a screening protocol and became pioneers in performing airport employee screening prior to the current debate on employee screening. In 2007, CAS was asked to pioneer the program to screen airport employees immediately after a security breach at a CAT X airport involving airline personnel. CAS has been providing employee screening and vehicular traffic security services ever since. CAS's approach ensures airports are in compliance to your airport/airline security plan and the TSA regulations governing access control.

  • Screening of airport employees
  • Walk-through metal detectors (WTMDs)
  • Hand-held metal detector searches (HHMDs)
  • X-ray search of personal property
  • Physical property search

CAS has been providing services under the SPP since the program’s inception in 2002 and is the largest, most experienced provider of SPP services to the TSA. CAS’s primary responsibilities are to provide checkpoint passenger and baggage screening and checked baggage screening in order to prevent the introduction of explosives and prohibited articles into the sterile areas. We utilize the application of WTMD, Advanced Imaging Technology (AIT), X-ray imaging, Explosive Detection Systems (EDS), 3D Computed Tomography (CT), physical search, and other detection innovations.
