Security experts and engineers have been showing off the latest technology at this year's Security and Counter-Terrorism Expo.
The event, at London's Olympia, brought together people from around the world to demonstrate what is on offer to defence forces tackling threats from cyber terrorism to drone misuse.
Timothy Bean, from Fortem Technologies, explains how the device his company has brought to the event could effectively capture a drone.
"When something is seen in the airspace, the DroneHunter will autonomously take off without a human pilot.
Mr Bean then explains that a net will come out of the DroneHunter at 80mph and capture the enemy drone in it's netting - then it will tow it away to a safe location.
Airborne devices like the drones that brought Gatwick to a standstill in December can be used as a modern menace, but some could be used as a potential weapon.
Many of the companies at the event have come up with different ways of stopping them.
The exhibition further looks at current and future threats we face, from vehicle improvised explosive devices, artificial intelligence and cyber terrorism as well as the threat of drones.
