Different VPN protocols determine how the VPN tunnel is made and how data is transmitted. A good example is NordVPN and Cyberghost VPN, two of our best VPN services.What are VPN protocols and which are the worst and the best? VPN protocols help secure your internet connection and affect things such as speed and security. Unsurprisingly, commercial VPNs are dropping support for L2TP. However, we recommend that you use L2TP/IPsec as your last option-when you can't connect to OpenVPN for some reason. Its primary selling point is stability and wide support, similar to OpenVPN. Plus, you might want to stay away from L2TP like a plague, just like IKEv2, due to alleged reports of IPsec being compromised by the NSA.Īnd when it comes to speed, L2TP/IPsec isn't the fastest VPN protocol. One of the key reasons being it uses UDP by default on port 500. However, L2TP is not as secure as the open-source OpenVPN protocol. Like IKEv2, it adds a layer of the IPsec suite for secure tunneling that uses AES-256 bit encryption. L2TP stands for Layer 2 Tunnel Protocol and, at its most basic, is just a tunneling protocol.

Best vpn protocol how to#
Check out our article on what is OpenVPN and how to use it for more details. Some example scenarios where you might want to use OpenVPN include when connecting to public Wi-Fi. In summary, OpenVPN is your go-to choice if you need a VPN protocol that is widely available and secure.
Best vpn protocol plus#
While this is a plus for expert users, it can be challenging for beginners. For starters, UDP prioritizes speed, and TCP is for reliability.Īdditionally, OpenVPN is highly configurable, allowing you to dictate various things beforehand. OpenVPN implements both the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP), so you can choose which your VPN should run on depending on your use case. It also uses other security protocols, making it one of the most secure VPN protocols. But unlike Wireguard, OpenVPN is older and hence is ubiquitous among commercial VPN providers-it's often the default VPN protocol for most paid VPN services.Īlongside 2048-bit RSA authentication, OpenVPN utilizes the industry-wide AES-256 bit key encryption standard for security. Similar to Wireguard, OpenVPN is also open source. Logo credit: OpenVPN Inc./ Wikimedia Commons Primary use case scenarios include online gaming, video streaming, and downloading large files over the internet. For instance, instead of using industry standards like the AES-256 bit key encryption protocol, it uses newer cryptographic techniques like the ChaCha20 encryption algorithm.Ĭonsidering its specifications, Wireguard is the best VPN protocol if you want the fastest speed over a VPN connection. Wireguard leverages a wide range of modern encryption techniques, which gives it an edge over old protocols.
Wireguard also doesn't hurt battery life as much as other VPN protocols on mobile devices.
The lean codebase also makes Wireguard easier to implement and easier to use, something you'll notice in all VPN services that use the protocol. The protocol's top-notch speed is all thanks to its smaller codebase. Wireguard's key strengths include its open-source nature and fast speed. The only caveat is it's not ubiquitous in commercial VPN services like older protocols. Although it's in development, Wireguard is available to use. It's a fast and open-source VPN protocol still in active development. Wireguard is the latest kid on the block.
