Proton VPN is probably one of the best VPNs out there. Has open source clients, is based in Switzerland so under their strong jurisdiction for privacy and data protection, doesn’t keep logs or sell data, has good speeds, includes useful features, etc. I’d definitely recommend it, as well as Proton’s other products.

Their free VPN is good enough that I have not had to purchase their paid version, but I probably will anyway.

Proton is a great company with a pretty good record, but I wouldn’t recommend them for passwords when Bitwarden exists. Proton only open-sources their clients, and for service based offerings like mail or VPN I don’t care about the servers being open-source, but for password management I want to be able to host my own (making sure that self-hosted mail gets properly received by Gmail is pain and self-hosting a huge VPN network is basically impossible).

According to r/VPNTorrents, Proton and AirVPN are the only recommended VPNs since they are the only well-established privacy-respecting ones left. New ones are popping up with promise, like Azire, but time will tell. As for Proton, I decided against it because of limited port forwarding and lack of IPv6 compatibility and settled on AirVPN. Also, I personally try to avoid keeping all my eggs in a single corporation’s basket, so I cannot advise buying into the full Proton suite if you’re remotely tech savvy and/or privacy-concerned. But they are genuinely great products if you have no desire to do any tinkering or shopping around. I just can’t see the appeal in my VPN activities being directly tied to my email. Oh and I almost forgot, I switched from PIA due to their lack of IPv6 support and acquistion by Kape, a known adware company.
