As of January 2020 ProtonVPN has undergone an independent audit by SEC Consult. SEC Consult found some medium and low risk vulnerabilities in ProtonVPN's Windows, Android, and iOS applications, all of which were "properly fixed" by ProtonVPN before the reports were published. None of the issues identified would have provided an attacker remote access to a user's device or traffic. You can view individual reports for each platform at protonvpn.com.

IVPN has undergone a no-logging audit from Cure53 which concluded in agreement with IVPN's no-logging claim. However, IVPN has not undergone a more comprehensive security audit by an independent third party, and therefore cannot be strongly recommended at this time.
We have still chosen to list it on this page with the assumption that an audit will be published soon. IVPN has hired Cure53 to undertake a comprehensive audit covering the IVPN website, public and internal server infrastucture. They expect the audit to begin in November 2019 and be completed by the 6 auditors in January 2020.
IVPN has 77 servers in 31 countries at the time of writing this page. Typically the more servers a provider offers, the better. IVPN has a decent (but not exceptional) server count that will most likely provide adequate coverage to most users.
