Byrna Technologies Inc.
A maker of personal security devices, Byrna builds CO2-powered launchers and less-lethal projectiles — such as its Byrna SD and Byrna LE models — for civilians, law enforcement, and security professionals who want a self-defense option that doesn't require a traditional firearm or background check in many places. It began in 2005 as Security Devices International, producing 40mm and 37mm munitions for law enforcement and military use, and took the "Byrna" name in 2020 from a South African affiliate it had acquired, rebranding around its flagship self-defense line.
