Gibraltar-based VPN IVPN now offers users the choice to connect using WireGuard, an in-development, open-source protocol that aims to rival current standards in speed and security.

“We are more excited than ever to launch what we believe is the future of VPN technology, WireGuard!”, said IVPN CEO Nick Pestall in a blog post announcing the feature.

The new protocol, which IVPN describes as “extremely fast, secure and simple”, is available as a click-and-connect option within its iOS, Android, and MacOS apps. Linux users can connect through WireGuard’s native implementation, but Windows is currently not supported.

WireGuard, developed by Jason A. Donenfeld, is designed to be “easily implemented in very few lines of code”, says the official WireGuard website.

“Its simplicity and size ensure a much smaller attack surface relative to other protocols (roughly 1% of OpenVPN). This greatly enhances its ability to be peer reviewed and audited” adds Pestall in his blog post.

IVPN’s introduction of the protocol does come with an explicit warning to users, though, explaining that WireGuard is still “under heavy development” and only recommended for “testing purposes and in situations where security is not critical”.

This word of caution is echoed on WireGuard’s own website, which says: “WireGuard is not yet complete. You should not rely on this code. It has not undergone proper degrees of security auditing and the protocol is still subject to change.”

For security reasons, IVPN has assured users that WireGuard VPN servers will be kept completely separate from its OpenVPN servers.

IVPN, alongside a handful of other VPN providers, is sponsoring WireGuard’s development and encourages all customers to make a donation if they have the means.

Those who haven’t already subscribed to IVPN’s service can trial the apps for three-days free of charge through a dedicated WireGuard page, with no payment details required.

IVPN isn’t the first provider to offer the protocol; Swedish-based Mullvad first implemented it in March 2017, making it one of the first known VPN providers to do so. AzireVPN followed suit in September 2017.

Private Internet Access is another provider that hopes to integrate the protocol into its apps in the near future to ensure that it remains at “the forefront of VPN technology.”
