I found one one on here right after submitting this.

Multicopter Defender looks just like DroneDefender, which I guess was first by 2 or 3 years.

Raysun makes a few gadgets; more notably a net launcher and also a bazooka that launches a self-inflating flotation device on the end of a line. At their site are links to videos with brief footage of a drill exercise in which a consumer-class drone drops a smoke bomb on baseball players and MulticopterDefender is shown along with a counter-drone launching a net over it in mid-air :D
