There are numerous VPN protocols, and which protocol a VPN utilizes has a huge affect on how it functions. Some protocols are a good deal improved than some others. Luckily, obtaining the very best VPN protocol is quick as there are only a couple of candidates.

What Is a VPN Protocol?

In shorter, a protocol is a established of rules that govern how equipment inside a community converse with each and every other. When you connect to the world-wide-web, for case in point, you are making use of the hypertext transfer protocol (HTTP) to let your laptop chat to the site you are accessing. A VPN protocol is a precise type of protocol meant for—you guessed it—VPNs.

A protocol can involve all kinds of info. In the circumstance of HTTP, it is a set of rules encompassing how two devices can exchange facts (in the variety of HTML documents) as very well as some simple stability policies.

When you use a VPN, you are rerouting your relationship by means of a server operated by your VPN services. To do so securely, the VPN requirements to use a separate protocol, a single that’s created for VPNs and is made up of details about the encryption employed in the connection as very well as some other specialized information.

How a VPN Protocol Influences You

This may perhaps audio a minimal abstract, but it has an effect on you instantly: A very good protocol will be a ton a lot quicker and a ton far more safe than a undesirable just one. Some protocols are gradual because they require extra steps when sending facts, even though others are less protected for the reason that they include a flaw or use an encryption crucial that has a recognised weak point.

To assist you pick the ideal VPN protocol for you—and by extension the ideal VPN, period—we’re likely to go around the protocols we have occur across the most, as properly as some proprietary types. We’ll start out with the very best types out there, OpenVPN and WireGuard, and get the job done our way down from there.


OpenVPN is probably the most well known VPN protocol out there. Nearly all VPN suppliers present it to their clients in some form or a further. It provides each speed and safety, without the need of any sizeable trade-off in either. When using OpenVPN, most VPN providers will let you to select amongst TCP and UDP. You’re usually greater off heading with UDP, as it’s more quickly.

To give you an strategy of how fantastic OpenVPN is, just about all VPNs use it as their default. In the wide vast majority of cases, there is no good reason to use something else. The only exceptions are WireGuard or notably solid proprietary protocols like NordLynx and Lightway, all of which we make clear below.

In actuality, we would go so significantly as to propose not using any VPN that does not present OpenVPN, and to be a little leery of any service provider that doesn’t have it as their default—besides the exceptions we talked about previously. We talk about just one instance in our Surfshark vs. ExpressVPN piece, in which we docked Surfshark some significant details for defaulting to a mediocre protocol.


For most persons, most of the time, OpenVPN seems to be the ticket. On the other hand, in 2021 a really attention-grabbing new protocol came out, which has the prospective to dethrone OpenVPN. Named WireGuard, it’s fast as greased lightning, often beating OpenVPN on a comparable server load—though keep in thoughts that there is a lot far more than just the protocol to identify a VPN connection’s pace.

Still, WireGuard looks stable. It has had at least just one great proprietary protocol centered off of it: NordVPN’s NordLynx. That claimed, there have been some rumblings about how personal WireGuard seriously is, as it looks to shop users’ IP addresses indefinitely in some circumstances.

That reported, if pace is your overriding issue, WireGuard may be an superb different to OpenVPN. While in general we want OpenVPN, WireGuard will come in a close second.


Our third entry is the Protected Socket Tunneling Protocol, or SSTP, which dates from the early 2000s and is generally regarded to be quick and protected, while frequently performs a minor much less very well than OpenVPN. If for regardless of what rationale you can not use OpenVPN, SSTP is a stable fallback alternative, while.

The key concern folks seem to be to have with it is that its code is owned by Microsoft, a corporation with a fewer-than-stellar standing when it arrives to privateness. Nevertheless it is unclear irrespective of whether Microsoft gathers data from SSTP connections or not, if it’s some thing you are fearful about, you may possibly want to prevent this protocol.

L2TP/IPsec and IKEv2/IPsec

This entry is two for the price tag of 1: both L2TP and IKEv2 are two relationship protocols that are usually paired with the IPsec security protocol to beef up encryption. In the two instances, you are creating a trade-off: L2TP is trustworthy, but slow, though IKEv2 is fast—very fast, even—but has protection difficulties.

In possibly scenario, they are an attention-grabbing alternative for builders as they’re a great deal far more versatile than OpenVPN. Most operate-of-the-mill customers, though, may not see a great deal of a distinction. Commonly, we only advocate working with these two if you have no other alternative.


From some of the better VPN protocols out there, we go to possibly a person of the worst available. Point-to-stage tunneling protocol (PPTP) is a VPN protocol relationship from the nineties—ancient in tech terms—which is not specially safe and very sluggish.

It is generally not utilised any more as it is out of date, but for some cause some VPNs nonetheless offer you it. Whichever you do, never use PPTP—especially if you’re doing anything at all delicate like utilizing BitTorrent to down load files or tunneling out of China.

Proprietary VPN Protocols

We’ll complete up by heading in excess of 3 fascinating proprietary protocols which have occur out. Developed by a VPN provider for its individual use, these protocols generally boast greater speeds, however some of them are a bit of a black box.


The Hydra protocol was designed for and utilised by Hotspot Shield and is a superior example of sacrificing some protection for velocity. It’s extremely fast but works by using weaker encryption—128-AES relatively than the 256-bit variant. It’s not the greatest offer, and the insane speeds Hydra checks at could be really worth it.


NordVPN also needed its own protocol, but it tweaked WireGuard to its liking relatively than developing one from scratch. The outcome is a blazing fast VPN protocol that appears really protected. It would be even improved if NordVPN fixed its servers, one thing we go in excess of in our write-up evaluating NordVPN vs ExpressVPN.


Very last but not the very least is Lightway, formulated from scratch by our general favourite VPN, ExpressVPN. Like NordLynx, it appears perfectly secure but is somehow even quicker than nearly anything else put out there, which include WireGuard. Although we wait to phone it the greatest VPN protocol—OpenVPN just has a much better pedigree and observe record—it is undoubtedly well worth examining out.
