There are three Proton for Business plans: With these two encryption mechanisms, your information is fully protected and only visible to those you choose. For example, if a Proton user sends an email to another Proton user, the data is never visible, even to Proton, during the exchange. They also use end-to-end encryption, complete encryption from start to finish. Since Proton's goal is privacy and security and not advertising, their zero-access encryption approach is much more secure. However, when their servers are hacked and compromised, attackers can access the encryption key, allowing them to read your data. Most cloud providers keep the encryption key to read emails and communications for targeted advertising purposes. Without your specific encryption key, which Proton does not possess, the bad guys cannot access your data. This data encryption-at-rest technology ensures that your data stays your data, even if Proton servers are hacked. Zero-access encryption protects emails received, even from other email providers, as the data is immediately encrypted and unreadable, even by the Proton service itself. With zero-access encryption, Proton encrypts received emails using the account owner's encryption key. Proton uses two types of encryption-zero-access encryption and end-to-end encryption.
