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!  

Note: Atlas VPN does not support PPTP, L2TP, or OpenVPN connection protocols.

  3. Changing the protocol





WireGuard® is a 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.

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.
