What Is the Best VPN Protocol? OpenVPN vs. WireGuard vs. SSTP and More

There are a number of VPN protocols, and which protocol a VPN works by using has a significant influence on how it features. Some protocols are a ton greater than other folks. Luckily, obtaining the greatest VPN protocol is simple as there are only a couple of candidates.

What Is a VPN Protocol?

In quick, a protocol is a set of guidelines that govern how units in a community converse with each individual other. When you connect to the world wide web, for illustration, you are employing the hypertext transfer protocol (HTTP) to enable your computer system discuss to the web page you’re accessing. A VPN protocol is a precise sort of protocol meant for—you guessed it—VPNs.

A protocol can contain all kinds of details. In the situation of HTTP, it is a set of rules encompassing how two gadgets can exchange data (in the sort of HTML files) as very well as some basic security procedures.

When you use a VPN, you’re rerouting your link by a server operated by your VPN provider. To do so securely, the VPN demands to use a different protocol, one particular that is created for VPNs and contains data about the encryption utilised in the connection as perfectly as some other complex specifics.

How a VPN Protocol Influences You

This may sound a tiny abstract, but it has an effect on you specifically: A very good protocol will be a lot faster and a ton much more protected than a poor a person. Some protocols are slow because they require more steps when sending information and facts, when other people are significantly less secure because they include a flaw or use an encryption key that has a recognised weak point.

To support you decide the very best VPN protocol for you—and by extension the most effective VPN, period—we’re going to go more than the protocols we’ve occur throughout the most, as effectively as some proprietary kinds. We’ll start out with the greatest ones out there, OpenVPN and WireGuard, and do the job our way down from there.


OpenVPN is in all probability the most popular VPN protocol out there. Practically all VPN vendors offer it to their prospects in some type or an additional. It gives both velocity and security, without having any significant trade-off in both. When utilizing OpenVPN, most VPN vendors will make it possible for you to pick in between TCP and UDP. You’re commonly much better off likely with UDP, as it is a lot quicker.

To give you an concept of how good OpenVPN is, virtually all VPNs use it as their default. In the broad greater part of cases, there’s no very good motive to use something else. The only exceptions are WireGuard or especially stable proprietary protocols like NordLynx and Lightway, all of which we clarify under.

In actuality, we would go so much as to advise not applying any VPN that doesn’t give OpenVPN, and to be a minor leery of any provider that doesn’t have it as their default—besides the exceptions we pointed out earlier. We discuss about just one case in point in our Surfshark vs. ExpressVPN piece, where by we docked Surfshark some serious factors for defaulting to a mediocre protocol.


For most persons, most of the time, OpenVPN appears to be to be the ticket. Nonetheless, in 2021 a extremely interesting new protocol arrived out, which has the probable to dethrone OpenVPN. Named WireGuard, it is quickly as greased lightning, often beating OpenVPN on a equivalent server load—though retain in brain that there is a ton additional than just the protocol to ascertain a VPN connection’s speed.

However, WireGuard seems to be reliable. It has had at least a person great proprietary protocol based off of it: NordVPN’s NordLynx. That mentioned, there have been some rumblings about how private WireGuard really is, as it appears to store users’ IP addresses indefinitely in some cases.

That mentioned, if pace is your overriding issue, WireGuard may well be an great substitute to OpenVPN. While general we choose OpenVPN, WireGuard arrives in a close 2nd.


Our 3rd entry is the Protected Socket Tunneling Protocol, or SSTP, which dates from the early 2000s and is typically regarded to be speedy and secure, though normally performs a tiny less nicely than OpenVPN. If for whatever purpose you just can’t use OpenVPN, SSTP is a strong fallback selection, while.

The most important problem people appear to be to have with it is that its code is owned by Microsoft, a business with a much less-than-stellar name when it arrives to privacy. However it’s unclear irrespective of whether Microsoft gathers data from SSTP connections or not, if it’s something you are apprehensive about, you may well want to prevent this protocol.

L2TP/IPsec and IKEv2/IPsec

This entry is two for the rate of a single: each L2TP and IKEv2 are two relationship protocols that are generally paired with the IPsec protection protocol to beef up encryption. In both of those cases, you are making a trade-off: L2TP is responsible, but sluggish, although IKEv2 is fast—very rapidly, even—but has safety challenges.

In possibly situation, they are an fascinating selection for developers as they’re considerably more flexible than OpenVPN. Most operate-of-the-mill buyers, nevertheless, might not detect a great deal of a variance. Typically, we only advise applying these two if you have no other preference.


From some of the improved VPN protocols out there, we go to almost certainly one particular of the worst out there. Point-to-place tunneling protocol (PPTP) is a VPN protocol courting from the nineties—ancient in tech terms—which is not specially protected and unbelievably gradual.

It’s frequently not applied anymore as it’s out of date, but for some rationale some VPNs still present it. What ever you do, really do not use PPTP—especially if you’re undertaking something delicate like utilizing BitTorrent to obtain information or tunneling out of China.

Proprietary VPN Protocols

We’ll finish up by likely over a few interesting proprietary protocols which have appear out. Produced by a VPN support for its have use, these protocols generally boast greater speeds, although some of them are a bit of a black box.


The Hydra protocol was developed for and applied by Hotspot Shield and is a superior instance of sacrificing some stability for speed. It is very rapidly but employs weaker encryption—128-AES fairly than the 256-little bit variant. It is not the major offer, and the crazy speeds Hydra checks at might be well worth it.


NordVPN also preferred its individual protocol, but it tweaked WireGuard to its liking alternatively than building 1 from scratch. The result is a blazing rapidly VPN protocol that looks very safe. It would be even better if NordVPN mounted its servers, a little something we go in excess of in our short article evaluating NordVPN vs ExpressVPN.


Last but not the very least is Lightway, developed from scratch by our all round favourite VPN, ExpressVPN. Like NordLynx, it seems completely safe but is in some way even quicker than anything else place out there, such as WireGuard. Even though we hesitate to connect with it the greatest VPN protocol—OpenVPN just has a far better pedigree and observe record—it is unquestionably value examining out.
