Founded in 2014 and based in Lyon (France) and Wilmington (USA), Elistair designs smart, automated tethered drone systems for perimeter protection, border surveillance, and event security. Its micro-tether technology solves the issue of drone battery life by enabling continuous flight when connected to a generator or the grid. The tether also secures data, preventing hacking and interference. Used in over 70 countries by armed forces, civil security, and private companies, Elistair collaborates mainly with national security and defense actors. It offers two patented product lines: KHRONOS, a fully automated tethered DroneBox, and SAFE-T and LIGH-T, which convert free-flying drones into tethered systems. Key clients include the French Defence Agency, Thales, US Army, UK police, Total, Paris Airports, ENGIE, Securitas, and Vodafone.
