Which is the fastest VPN protocol?

The fastest secure VPN protocol is WireGuard, and performance benchmarks show it to be three times faster than OpenVPN.

Our speed tests show that Catapult Hydra is even faster than WireGuard, but this is a closed source protocol and is only available on Hotspot Shield.

Although some older protocols (such as PPTP and L2TP) are faster than WireGuard, these should be avoided in all cases. These fast connection speeds are attributed to the protocol's weak encryption, making them useless as a privacy and security tool.
