Ok, but DRO doesn’t actually have any products for use against sea drones.

”DroneShield helps maritime facilities and vessels protect themselves from nefarious and negligent UAS intrusions. Maritime vessels are considered high value targets, with a high density of passengers or cargo on board. Terrorists can utilize drones to commit remote surveillance and terrorism on maritime facilities and vessels. DroneShield provides both portable and fixed systems to suit a range of counterdrone requirements.

Maritime authorities use DroneShield to protect docks, cargo facilities and passenger vessels from the threat of UAS intrusion. DroneShield sensors distinguish UAS from other common flying objects to provide users with a reliable drone detection solution. “
