Security audit of Mullvad app completed – please upgrade

20 September 2018  SECURITY

We recently requested an external security audit to be performed on our VPN app, version 2018.2.

An independent audit helps to discover potential security vulnerabilities and fix them, all resulting in an even better service. It also gives you the opportunity to judge whether or not we are technically competent enough to provide a service in which security is paramount.

Thanks to the audit's findings, we prioritized our improvements accordingly and released app version 2018.3.

Upgrade your app

So what does this mean for you, our customer? We recommend that you upgrade to the latest stable version of the app, which at the time of this post is 2018.3.

Download Mullvad now – this link and our website's Download button always point to the latest version.

Read the audit's results

We are quite pleased with the outcome of the audit. To quote the auditors themselves, "In sum, the assessment yielded a total of seven issues, which [is] an exceptionally small number given the complex field of the VPN software and the connected, vast attack surface."

The final report of the audit, carried out by Cure53 and Assured, will be publicized by Cure53 and on our blog on Monday 24 September.
