**A New Layer of Security at Lyon-Saint-Exupéry** Since July 3, 2026, Aéroports de Lyon has been trialing Ascento Guard, an autonomous outdoor security robot developed by Swiss company Ascento, on the parking lots of Lyon-Saint-Exupéry Airport. This two-month pilot makes Lyon the first airport in France to deploy such a solution, reinforcing its role as a living lab for VINCI Airports' innovation strategy. The robot works alongside human security teams and existing CCTV systems to enhance surveillance of parking areas, aiming to improve passenger peace of mind and incident detection. **How Ascento Guard Works** Ascento Guard is a rugged, all-terrain robot equipped with 360° cameras, thermal imaging, and integrated floodlights. It can navigate ramps, pedestrian zones, and various surfaces at a safe speed. Its AI enables advanced image analysis and event detection, such as identifying people, checking perimeter integrity, and spotting thermal or light anomalies day or night. With an eight-hour battery life and autonomous recharging, it can conduct near-continuous patrols. The robot is designed for deterrence, control, and detection missions, particularly in outdoor spaces like parking lots and industrial sites. **Privacy, Cybersecurity, and Regulatory Compliance** Aéroports de Lyon emphasizes that Ascento Guard incorporates data protection and cybersecurity measures from the ground up. Faces are blurred by default, and capture parameters can be configured to meet European GDPR requirements and airport authority standards. In an environment already using biometric systems like MONA and AI virtual assistants, this robot is presented as a complementary tool that strengthens security without being intrusive. The goal is to detect incidents—such as intrusions, suspicious behavior, or vehicle damage—while maintaining passenger trust and regulatory compliance. **Lyon as a Testbed for Airport Innovation** Lyon-Saint-Exupéry has been a VINCI Airports center of excellence for innovation since 2019, alongside Lisbon and London Gatwick. It has previously hosted world-first trials, including the Stan robotic valet parking system and the MONA facial recognition travel companion. This latest test of Ascento Guard underscores the airport's commitment to trialing cutting-edge technologies before they are rolled out across the VINCI network. For aviation professionals, such deployments highlight the growing role of AI and robotics in airport operations, from security to passenger services. **What This Means for ATPL and ATC Students** Understanding how autonomous systems like Ascento Guard integrate into airport security frameworks is increasingly relevant for future pilots and air traffic controllers. These technologies affect ground operations, emergency response protocols, and the overall safety ecosystem. As AI-driven surveillance becomes more common, aviation professionals must be aware of their capabilities, limitations, and the regulatory landscape governing their use. This knowledge will be essential for effective coordination with ground staff and security teams in modern airports.
