I’ve been using Proton Mail and VPN for a while now, and I’m just wondering how everyone else feels about them. I have this kind of inherent alight distrust of them just because they seem like they offer a lot for free and kind of have a Big Tech vibe about them, but there’s nothing for me to really substantiate that distrust with, its mostly just a feeling. That being said, I do use their services as mentioned and they work pretty well, even on the free teir. So aside from that one instance where they gave that guy’s info to the feds, is there any reason not to trust them with my data?
For that one instance, not doing so would have been illegal and probably gotten them hit with a major penalty.
Any email sent to Proton in clear text is 100% accessible to them at the point of entry. They basically promise you that they won’t look at it before encrypting it for storage. So if you trust their promise, it’s all good.
Any email that comes in already end to end encrypted with OpenPGP is not accessible to them ever, kind of. If their client gets hacked and starts sending unencrypted messages to them or someone else, then they have access.
The only way to have a zero trust environment is always having people (or businesses) send you messages encrypted with OpenPGP, and never using Proton’s clients (webmail, mobile app, and desktop bridge). That’s fairly unreasonable, and you might as well use any other email service at that point.
So, you can trust them as much as any other company, because unless you write and run your own email server (which, trust me, is a huge pain in the ass*), that’s your only option.
* I wrote and run an email service called Port87, which launched recently, and there are so many obstacles to doing this, even if you’re only running one user on one domain on one server.
