Is Proton Mail more secure than Fastmail?

Proton Mail has multiple security features that Fastmail does not, including end-to-end encryption and zero-access encryption. With Proton Mail, only you control your private key that’s used to decrypt messages on your device. Proton cannot access your email contents, contacts, attachments, calendar events, etc.

What’s more private, Fastmail or Proton Mail?

Fastmail emphasizes privacy by refusing to monetize your data, instead charging its users for the service. Nonetheless, Fastmail can access your email contents because they are not end-to-end encrypted. Additionally, Fastmail is based in Australia, and its servers are located in the United States. Both countries are members of the Five Eyes(new window) [https://protonvpn.com/blog/5-eyes-global-surveillance/] intelligence-sharing network. By comparison, Proton Mail cannot access your emails because they are encrypted with a private key that only you control. Proton is based in Switzerland, so our users are protected by Swiss privacy laws and beyond the reach of surveillance regimes.

What is the best Fastmail alternative?

Proton Mail offers many of the same features as Fastmail (and more). But when it comes to privacy and security, Proton Mail is significantly more advanced. Proton backs up its privacy claims with automatic end-to-end encryption and zero-access encryption, all of which is open source so that anyone can verify our code does what we say. Proton Mail also offers basic services for free, while Fastmail’s Basic plan starts at $2.50/month.

No one else should have the ability to access your data.

You get what you pay for. In the case of big tech, if you pay nothing, you get used. I quit using Gmail and switched to @ProtonMail
