On the top floor of a squat Singapore industrial estate, wedged between a railway depot and water reclamation plant, is a young security firm that’s shooting for the stars.

TRD is one of the world’s leading purveyors of anti-drone technology—a burgeoning industry worth some $1.1 billion last year and projected to grow to $7.4 billion by 2032. “Anti-drone is the hot topic right now,” says TRD CEO Sam Ong, a former officer in the Singapore Armour Corps, where he specialized in tank technology.
