The company Proton AG building an internet that protects privacy, starting with email. The group of scientists, engineers, and developers drawn together by a shared vision of protecting civil liberties online, created ProtonMail, an easy-to-use secure email service with built-in end-to-end encryption and state of the art security features. The goal is to build an internet that respects privacy and is secure against cyber-attacks.

All user data is protected by the Swiss Federal Data Protection Act (DPA) and the Swiss Federal Data Protection Ordinance (DPO), which offer the strongest privacy protection in the world for both individuals and corporations.
As 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 the company Proton AG to release the extremely limited user information we have.
End-to-end encryption means that no one but the intended recipient can read the message.
Messages are stored on ProtonMail servers in encrypted format. They are also transmitted in encrypted format between our servers and user devices. Messages between ProtonMail users are also transmitted in encrypted form within our secure server network. Because data is encrypted at all steps, the risk of message interception is largely eliminated.
With ProtonMail, privacy isn't just a promise, it is mathematically ensured.
ProtonMail’s zero access architecture means that your data is encrypted in a way that makes it inaccessible to the company Proton AG. Data is encrypted on the client side using an encryption key that the company does not have access to. This means the company doesn't have the technical ability to decrypt your messages, and as a result, is unable to hand your data over to third parties.
The company uses the open-source cryptographic solutions, based on Time-tested and trusted encryption algorithms. This guarantees that the encryption algorithms do not have clandestinely built-in back doors. ProtonMail’s open source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection.
Hardware level of security is provided by the owning and controlling the company’s own server hardware at several locations within Switzerland, so your data never goes to the cloud. All data centers are located at highly secure sites that require biometric access. This provides an extra layer of protection by ensuring your encrypted emails are not easily accessible to any third parties.
On a system level, the servers utilize fully encrypted hard disks with multiple password layers, so data security is preserved even if the hardware is seized.
Unlike competing services, Proton AG does not save any tracking information. By default, the company does not record metadata, such as the IP addresses used to log into accounts. As the company has no way to read encrypted emails, it does not serve targeted advertisements. To protect user privacy, ProtonMail does not require any personally identifiable information to register.
The company Proton AG uses Swiss-certified SSL and TLS encryption protocols, to secure communication between its servers and users’ computers, and to ensure that the infrastructure is not under control of US or EU government agencies.

The ProtonMail service has been designed with a strong emphasis on comprehensive security for everyone and usability. As a result, ProtonMail is very easy to use.
There is nothing to install, and no encryption keys to manage; if you can use Gmail, Thunderbird, or Outlook, you can use ProtonMail.
