Atlas VPN connection protocols

  • Updated

Atlas VPN offers two different connection protocols: IPSec/IKEv2 and WireGuard®. In this article you will find information on both of these connection protocols, so you can choose the one that suits you best!  


WireGuard® is an extremely simple yet fast and modern protocol that utilizes state-of-the-art cryptography. It is considered faster, simpler, leaner, and more useful than the current leaders of the industry. Thanks to it being only 4,000 lines of code there's less room for vulnerability and security flaws. It intends to be considerably more performant than OpenVPN. WireGuard® is designed as a general-purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances, and widely deployable. It is currently under heavy development, but it already might be regarded as one of the most secure, easiest to use, and simplest VPN solutions in the industry.

WireGuard® is a registered trademark of Jason A. Donenfeld.


IPSec/IKEv2 (Internet Key Exchange version 2) is a VPN encryption protocol and due to its robust 256-bit security, IKEv2 became one of the most popular industry-leading standards. IKEv2 is also one of the fastest protocols out there. However, since IKEv2 runs on the UDP 500 port only, some firewalls can block the traffic, therefore, the protocol may be less efficient when trying to connect from a heavily censored country or a restricted network.

Switching between VPN connection protocols might help you to resolve certain connectivity issues. If you are having any trouble connecting to VPN servers or receiving desired Internet connection speeds, test out a different VPN protocol. The protocol can be changed in the Atlas VPN application settings.
