Tutanota vs. ProtonMail: Which is the better secure email service – Guide
Although journalists and whistleblowers have been using secure email services for several years, ordinary individuals are now realizing the benefits of email encryption; It’s the only way to send and receive secure emails. Along with antivirus, password managers and a VPN, secure email is another necessary weapon in your digital armor. Two of the most popular encrypted email providers are Tutanota and ProtonMail. While both offer end-to-end encrypted email services, some differences in features and service technology can make one service better than the other for you. Email is the starting point for the most successful data breaches, and free email services offer only a limited level of security.
Tutanota is a free and secure email provider based in Germany. Its name derives from the Latin words “tuta” and “note”, which means “safe note”. Tutanota claims to be the most secure and private mailbox in the world. With research into quantum cryptography already underway, it’s hard to believe otherwise. ProtonMail is a free and secure Swiss email provider. Using open source architecture and zero knowledge, their security is so robust that not even they can read your emails. Their servers are also hidden under a mile of granite in an old military bunker with multiple password levels. An attack would have to be nothing short of nuclear.
Tutanota vs. ProtonMail: What is the best secure email service
Privacy
Let’s talk about the data laws under which these companies operate.
Tutanota:
Tutanota is based in Germany (one of the Fourteen Eyes). Germany may be one of the Fourteen Eyes, but it is protected by the German Federal Data Protection Act – a modification of the EU’s general GDPR law. Essentially, it prohibits the collection and use of personal data unless the law specifically allows it or you have given your informed consent.
Proton Mail:
ProtonMail uses its location in Switzerland to take advantage of DPA and DPO acts. Switzerland is known for being a neutral territory – being outside US and EU jurisdiction. Offering some of the strongest privacy protections in the world, its Federal Data Protection Act of 1993 strictly prohibits any processing of personal data without explicit consent.
However, on September 5, 2021, the Swiss government forced ProtonMail to hand over IP addresses of French activists accused of theft and destruction of property. In this case, the French authorities asked the Swiss government for help.
The following day, ProtonMail stated in its privacy policy statement that it may be legally required to record someone’s IP address as part of a Swiss criminal investigation. However, it also stated that the law cannot force you to compromise encryption.
Safety
Tutanota:
Tutanota encrypts the email subject, body and all attachments. The bonus is an end-to-end encrypted address book and calendar, ensuring your contacts and meetings are kept private. It combines 128-bit AES and 2048-bit RSA protocols to provide end-to-end protection. Its stronger key programming likely makes it more secure than 256-bit AES. Emails for non-Tutanota users are encrypted using AES-128 bits. Passwords are encrypted using bcrypt and SHA256, with connections to Tutanota servers secured by TLS.
Tutanota encrypts more sections of your email and inbox than ProtonMail (your calendar and address book), as well as providing zero-knowledge text search. No one at Tutanota can see what you are looking for in your emails. Tutanota also makes it impossible to trace messages back to the user at least using their IP. Tutanota also differs from ProtonMail by fortifying 2FA with U2F which provides an additional layer of security.
Proton Mail:
ProtonMail offers nearly the same level of end-to-end encryption, although it does NOT encrypt email subject lines. What they should get is usability: Leverage conversation views, group sends, and Bond-style self-destructing emails for quick security. However, your full-text searches are NOT encrypted.
Similar to Tutanota, ProtonMail also makes it impossible to track users by their IPs. ProtonMail encrypts your emails like Tutanota, except it uses 256-bit AES, known as the gold standard of encryption. Messages for non-ProtonMail users are password protected, expire after 28 days with no subscription required. It remains, however, up for the user to share the password securely. ProtonMail and Tutanota messages are encrypted every step of the way, leaving little or no room for interception. Messages are encrypted while:
Sending emails to non-users
Tutanota:
Tutanota takes no chances. For end-to-end encryption between Tutanota users and non-users, users must securely change a password first. This ensures that the message can only be read by the intended recipient and verified. The question is, do you want the hassle of Tutanota’s additional password step for extra U2F authentication and a zero-knowledge full-text search? Or are you willing to sacrifice your subject line to take advantage of ProtonMail’s zero-knowledge calendar and end-to-end encrypted address book?
Proton Mail:
ProtonMail allows you to select an “Encrypt Out” option that enables end-to-end encryption between ProtonMail users and non-ProtonMail users. Nothing among you can be read, not even by the creators themselves. Otherwise, messages are encrypted with TLS (all popular email providers support TLS). These encrypted messages are not end-to-end protected, which means the provider can read and deliver your messages. ProtonMail does not provide end-to-end encryption on subject lines or recipient/sender email addresses. This means that emails sent to popular providers that do not offer end-to-end encryption are likely to retain a copy of the email.
device support
Tutanota:
In addition to a web version, Tutanota has desktop clients for Windows, Mac OS and Linux, with apps for Android, iOS.
Proton Mail:
ProtonMail can be used on the web like regular email. Or you can download the app for Android or iOS. As a paid user, you can also install the ProtonMail Bridge app. It runs in the background to encrypt all emails going in and out of your computer.
Additional features
Tutanota:
Tutanota has an autoresponder, custom domain aliases, and secure calendar features. One of Tutanota’s exceptional features is your SecureConnect. It allows you to inject a code into your website that creates a contact form as secure and private as Tutanota.
Proton Mail:
ProtonMail has many features, including an autoresponder and custom domain aliases, as well as a secure calendar, which is still in beta. It also has the ProtonMail Bridge — a feature which runs in the background and encrypts messages from applications with IMAP and SMTP support. However, it is only available for desktop devices (Windows, macOS, Limux).
