6 Types of VPN Protocols, Compared: Which is the Best to Use?

1

OpenVPN

In most cases, OpenVPN or WireGuard will be your best bet. PPTP is a protocol we don’t recommend using because of its relatively low-level encryption. However, you could try this protocol when privacy and security are not your highest priorities, such as for unblocking streams. If OpenVPN is not supported or does not work well for whatever reason, you could consider using L2TP/IPSec or IKEv2.

Like some other VPN protocols on this list, IKEv2 (Internet Key Exchange) was also developed by Microsoft with Cisco. This protocol is the successor of IKEv1. It’s particularly popular among mobile users because it does an excellent job of establishing a reconnection. Similar to L2Tp, IKEv2 also uses IPSec for encryption. Even though Microsoft worked on it, IKEv2 is not a completely closed-source protocol; we do have open-source implementations.

WireGuard

In essence, every VPN has to strengthen WireGuard’s wobbly privacy to benefit from its speed and security. That’s why we recommend using WireGuard-based protocols only if they come from reputable VPN providers. NordVPN, for example, fixes WireGuard’s privacy issues with the so-called “double NAT system” (network address translation). This allows them to establish secure connections without storing identifiable data on their servers.
