In addition to this, ProtonMail also supports sending encrypted emails to other email providers such as Gmail, Yahoo and AOL via symmetric encryption. Secure Communication With Other Email ProvidersĬommunication between ProtonMail users is encrypted by default, which is denoted by the presence of a blue-colored lock icon. Since your emails are encrypted, there's no way even for the staff to read your emails.

Also, it doesn't track or record information such as the user's IP address. ProtonMail doesn't require any information that can be used to personally identify an account holder while signing up. The latter cannot be recovered if you forget it. ProtonMail requires two passwords - one for signing in and one for decrypting your mailbox. Although message data is already encrypted before being sent, SSL adds an extra layer of security, preventing man in the middle attacks. ProtonMail uses SSL for communication between its servers and your computer. Apart from the fact that your data may survive a nuclear holocaust, this also ensures an extra layer of hardware security. ProtonMail claims that its primary datacenter (which itself is guarded by multiple passwords on a system level) is located under 1000 meters of granite rock, in a heavily guarded bunker that can survive a nuclear attack. In addition to this, ProtonMail ensures that your data stays on its servers, so that it is never exposed on the cloud. These laws are some of the strongest privacy protection laws in the world.Īs ProtonMail is outside of US and EU jurisdiction, only a court order from the Cantonal Court of Geneva or the Swiss Federal Supreme Court can compel us to release the extremely limited user information we have. The ProtonMail email servers are located in Switzerland, and your data is protected by the Swiss Federal Data Protection Act, as well as the Swiss Federal Data Protection Ordinance.
