In the midst of technological evolution, Mullvad, the Swedish VPN provider, takes a step further by integrating GotaTun, an in-house implementation of WireGuard. This development marks a strategic turning point, as it allows for optimizing the performance and stability of its services. Discover how this initiative fits into Mullvad’s digital transformation.
The 3 key points not to miss
- Mullvad deploys GotaTun, a unique implementation of WireGuard written in Rust, to improve the stability of its VPN services.
- The switch to GotaTun allows Mullvad to free itself from the technical constraints associated with using wireguard-go, especially on Android devices.
- The transition is accompanied by new features such as multihop and DAITA, enhancing user security and privacy.
GotaTun: a new step for Mullvad
Mullvad, a renowned player in the VPN field, has recently integrated GotaTun, an implementation of WireGuard written in Rust. This decision stems from the desire to offer better stability and reduce frequent crashes encountered with wireguard-go, particularly on Android devices. By turning to internally developed technology, Mullvad thus strengthens its technical independence and optimizes the management of its services.
The limitations of wireguard-go
Wireguard-go, although the standard for many VPN providers, has shown its weaknesses. Mullvad found that the majority of failures in its mobile application came from this module, despite the fixes applied over the years. Moreover, the complex integration between Rust and Go added a layer of technical complexity that hindered the maintenance and performance of the service.
Improvements and new features
With GotaTun, Mullvad has not only improved the stability of its services but also introduced additional features. For example, multihop and DAITA are now natively integrated, simplifying the software infrastructure. These innovations allow Mullvad to offer a smoother and more secure VPN experience to its users while enhancing the privacy of their data.
The future of VPN at Mullvad
The development of GotaTun is part of a series of initiatives aimed at making WireGuard the central pillar of Mullvad’s technical offering. By moving away from OpenVPN, which is scheduled to go offline in January 2026, Mullvad focuses on optimizing WireGuard to meet modern challenges, such as censorship and network surveillance. Thanks to advanced obfuscation methods and a secure infrastructure, Mullvad continues to position itself as a leader in the VPN field.
History of Mullvad
Founded in Sweden, Mullvad quickly established itself as a VPN provider prioritizing transparency and security. Known for its strict no-logs policies and for offering an anonymous service to its users, Mullvad has always relied on technology to stay at the forefront of personal data protection. With the introduction of GotaTun, Mullvad continues to strengthen its position by offering innovative and secure solutions.
