What are VPN protocols?

A VPN protocol is a set of rules or instructions that determine how data routes between your device and the VPN server. VPN providers rely on protocols to ensure a stable and secure connection. Every VPN protocol has its own pros and cons when it comes to speed, security, and stability.

IKEv2 - The fastest VPN protocol

- Excellent speed - 5/5
- Excellent security with strong encryption - 5/5
- Very stable - 5/5
- Overall, it is an excellent choice for supported devices - 5/5

OpenVPN - a time-tested VPN protocol

OpenVPN is the most popular and among the easiest VPN protocols to use, supported on a wide range of devices. We recommend using its UDP protocol for streaming and downloading. At the same time, TCP works best when you need additional, especially when connected to public Wi-Fi networks. OpenVPN is available across our desktop and Android apps out-of-the-box.

It depends on your needs. If you are serious about security, we recommend going with OpenVPN (TCP). If you want to achieve the best speeds possible, IKEv2 and OpenVPN (UDP) are the best solutions. Anyway, IKEv2 and OpenVPN have never been compromised yet.
