The story of Byrna Technologies Inc. is one of adaptation, innovation, and a keen understanding of the evolving landscape of personal security. Founded in 2005 as Security Devices International (SDI), the company initially focused on developing less-lethal solutions primarily for law enforcement and military markets. However, a shift in focus towards the consumer market, coupled with a rebranding to Byrna Technologies in 2019, propelled the company to new heights, establishing it as a leading name in the less-lethal self-defense industry.
