ProtonVPN is a virtual private network (VPN) service provider operated by the Swiss company ProtonVPN AG. The company is a beneficiary of Proton Technologies AG, the company behind the email service ProtonMail. According to ProtonVPN's official website, ProtonVPN and ProtonMail operate on "completely segregated infrastructures" for technical security reasons.
ProtonVPN AG is a beneficiary of Proton Technologies AG, the company behind the email service ProtonMail, and Fondation Genevoise pour l'Innovation Technologique (FONGIT), a non-profit foundation financed by the Swiss Federal Commission for Technology and Innovation. According to ProtonVPN's official website, ProtonVPN AG is legally separate from Proton Technologies AG.
- Secure Core – a feature that aims to protect users against traffic correlation attacks.
- Strong Encryption – all traffic is encrypted with AES-256, key exchange is done with 4096-bit RSA, and HMAC with SHA-384 is used for authentication.
- Forward Secrecy – encrypted traffic cannot be captured and decrypted later if the encryption key from a subsequent session gets compromised.
- No Logs Policy – by TheBestVPN.com team, ProtonVPN has been listed as top 5 for 'Strict no logging' VPN.
- Strong Protocols – ProtonVPN only uses the OpenVPN protocol.
- DNS Leak Prevention – this prevents that connections to the default DNS servers of the system are made to prevent leaks.
- Kill Switch – their software has a built-in kill switch that will interrupt a user's Internet connection if their VPN server connection drops. This would help to keep the user's true IP address from being accidentally shown.
- Tor over VPN – selected Tor servers allow users to route all of their Internet traffic through the Tor anonymity network.
In a July 2017 review by TechRadar, ProtonVPN received four out of five stars; the verdict read, "ProtonVPN offers great security and we love the Windows client, but there are cheaper services around." A November 2017 review of the free version by the same TechRadar writer concluded: "If you can live with a choice of only three locations, ProtonVPN's free plan is an excellent choice [...] It’s well worth checking out, if only as a backup for your existing VPN service." Another November 2017 review, however, by That One Privacy Site states of its paid service: "ProtonVPN got a lukewarm reaction from me [...] In the end, (especially given its high asking price), I believe there are better services available on the market."
In 2018 ProtonVPN partnered with Mozilla to pilot selling VPN subscriptions via showing ads in the Firefox browser.
A very detailed January 2019 review rated Proton VPN at 3.5/5, with very good security, reasonable performance, but few server locations.
