Amongst the top VPN protocols OpenVPN by far is the best. OpenVPN technology uses the highest levels (military standards) of encryption algorithms i.e. 256bit keys to secure your data transfers.

Apart from that, OpenVPN protocols also uses what is called "authenticating data" using digital certificates. This is just like using a passport to travel around the world, when you send data to a person the recipient can then certify the source of the data transfer.

OpenVPN is also known to have the fastest speeds even in the case of long distance connections that have latency. The protocol is highly recommended for streaming, downloading files  and watching live TV. In addition to speeds, the protocol is stable and known to have fewer disconnections compared to its many counterparts.
