There is a latest technology in the U.S. called iTwin USB file sharing device. The iTwin allows two computers to share files over the internet. You just need to plug the other half of the iTwin into your computer and the other half to where would you like to send or receive a file. Security wise the iTwin uses 256-bit AES encryption to ensure that the data is secured while being transferred.

It has a price of $99 plus $10 additional for delivery.
