Drone security is much in the news. Federal agencies have issued warnings about foreign manufactured drones that use the mfrs internet access points for updates, etc.
This presents problems for many security conscious buyers, since the vast majority of marketed drones are Chinese. A few Chinese drones do not use such access points.
If your agency or company needs include secure drone ops, at present you must do your own research to decide appropriate purchases. You can also rely on reputable sellers, such as Vertigo Drones, for timely information, sales and service.
