CASRA

What CASRA does

CASRA (legally APSS Software & Services AG) is a Zurich-based private software company that develops computer-based training and competency assessment systems for X-ray security screeners. Its flagship platform, the X-Ray Tutor (XRT/XRT4/XRT5), covers the full screener competency lifecycle, from pre-employment selection (X-Ray ORT) through initial and recurrent training to certification (X-Ray CAT), and supports single-view, dual-view, and 3D CT imaging technologies. The platform incorporates an individually adaptive training algorithm grounded in 25+ years of cognitive research originating from the University of Zurich's Visual Cognitive Research Group (VICOREG, founded 1999), and is complemented by add-on modules for customs high-energy X-ray, biosecurity, color vision testing, and the Airport Checkpoint Effectiveness Simulation (ACES) benchmarking tool. CASRA earns revenue through annual software subscriptions (single and concurrent licenses), one-time lifetime licenses with optional updates, professional training services, and content customization engagements. The company sells primarily to government aviation authorities, customs and border agencies, airport operators, and critical infrastructure screeners across at least 17 countries, leveraging direct enterprise field sales, public tenders, and regional channel partners such as Aerotech Chile and Protactics. Official regulatory recognition from the German Federal Aviation Office (LBA) and Federal Police (BPOL), combined with ICAO Annex 17 and ECAC compliance, functions as a procurement gating factor in regulated markets.

Core offering

CASRA develops and sells computer-based training (CBT) and testing software used by aviation security authorities, customs agencies, and airport operators to train, assess, and certify X-ray security screeners. Its X-Ray Tutor platform supports single-view, dual-view, and 3D CT imaging technologies and is complemented by competency assessment tests (X-Ray CAT), pre-employment screening (X-Ray ORT), and benchmarking tools (ACES). Revenue is generated primarily through software licensing (annual subscriptions and lifetime licenses) plus professional training and content customization services.

Product overview

CASRA offers a unified platform architecture called the CASRA Solution, combining multiple products and modules for X-ray security screening. The core offering is X-Ray Tutor 5 (XRT5), a computer-based training and testing platform supporting single-view, dual-view, and 3D CT imaging technologies. Complementary products include X-Ray CAT for competency assessment testing and X-Ray ORT for pre-employment assessment. The platform is available in standard and Expert versions, with Expert allowing customers to create custom content. Add-on modules include 3D CT Training, Customs High Energy X-ray, Theoretical Block for e-learning, and Waggoner's Color Vision Test. Supporting tools include the Airport Checkpoint Effectiveness Simulation (ACES) for checkpoint comparison and TIP Data Tool for Threat Image Projection data analysis. The solution serves aviation security, customs, cargo, mail, critical infrastructure, and other security screening environments.
