The most recent major tunneling protocol, WireGuard offers by far the best connection speeds, all while maintaining security. This VPN protocol is considered secure, but there is one concern: L2TP/IPSec was co-developed with NSA, and there are suspicions that there may be backdoors to L2TP/IPSec traffic.
L2TP itself is a combination of two protocols that preceded it: Layer 2 Forwarding Protocol and Point to Point Tunneling Protocol. L2TP creates the tunnel and handles authentication. Layer 2 Tunneling Protocol (L2TP) doesn't have any encryption, so it also uses the Internet Protocol Security (IPSec) with 256bit AES variant. On the other hand, this allows for stable connections and is good for connecting to remote servers. Transmission Control Protocol (TCP) - usually requires multiple data verifications, which in turn slows down the data exchange process.User Datagram Protocol (UDP) - less data verification, therefore quite fast.OpenVPN uses two types of standard network protocols: It relies on the OpenSSL crypto library - an index of secure cryptography algorithms that make your tunnel safer. OpenVPN uses TLS with SSL/TLS for private key exchange. You can use it with 3DES and AES for encryption, with the latter being the safest method. The protocol also supports advanced cipher functions. This allows for virtually seamless switching between wifi and mobile data. The reason for that is that when the connection with a VPN server is interrupted, you will be automatically reconnected. Internet Key Exchange version 2, or IKEv2 for short, is very common on VPN mobile apps. Here are the most common VPN protocols in more detail: Now that we know the basics of a VPN protocol, let’s take a look at the most common ones. We discuss which protocols are best for different use cases further down in the article. Therefore, when it comes to specific purposes when security is less important than speed and vice versa, it is best to use different protocols that prioritize different aspects of the data exchange process. But with less encryption, online traffic becomes less secure.

The less encryption and verification (bubble wrap), the faster data delivery is. But if you're sending a baseball bat to your cousin, fragile stickers and bubble wrap won’t be necessary.ĭifferent VPN protocols are like the bubble wrap - or the absence of it - when it comes to sending data over the VPN. If you want it to reach her in one piece, you'll have to wrap it in bubble wrap, add a "fragile" sticker on the box, and choose a reputable delivery service. Let’s say you’re sending an expensive tea set to your grandma abroad. It is sort of similar to sending a package via post in real life. They establish VPN tunnels to safely exchange data. However, worry not because in this article, we’ll explain what VPN protocols are, how they work, take a look at a couple of different ones, and suggest which VPN protocol is the best for particular use cases.Ī VPN protocol is a set of rules on how the data will be packaged and sent over a private network. Such descriptions are often highly technical and not easy to understand if you don’t have the technical knowledge. You’ve probably seen such names as OpenVPN or WireGuard, or heard something about their speed and other properties. But if we go deeper, there is more to fiddle with - VPN protocols.

Using a VPN is not rocket science - all you need to do is download the app, choose a location and press the connect button.
