In this article, you can learn more about all the protocols that you can use with Surfshark.
A protocol is a set of rules that negotiates and maintains the connection between your device and the Surfshark VPN server. Almost everything you do online is based on sending and receiving information. Your information has to be divided into small chunks of data (packets) to send it. Protocols determine in what order packets will be sent, what encryption will protect them, etc. All protocols used at Surfshark are fast and secure, and it is up to you if you just stay with the default option or switch to your preferred protocol.
Different protocols have advantages of their own. Some protocols guarantee better speed and image video/audio quality, while others – a more stable connection. Therefore, if you experience some connectivity issues, you should try changing the protocol at first.
