Additionally, the encryption protocols used in Tutanota enable us to easily upgrade to new algorithms and add support for Prefect Forward Secrecy.

Tutanota encrypts not just bodies and attachments of emails, but also the subject line, which can contain very sensitive information. ProtonMail uses PGP encryption, which lacks important requirements that Tutanota is able to fix. In addition, there are quite important differences in the encryption methods used. One major differentiation here is that in Tutanota external recipients can access the entire email thread via the shared password while recipients of encrypted messages from Proton Mail are limited to just seeing one message. This information can then be shared with other members of the Five Eyes allegiance.Both Proton Mail and Tutanota offer end-to-end encryption for all emails, and both enable users to use a password for encrypting emails sent to recipients that don’t have an address with an encrypted email provider. (And in the U.S., emails are considered “abandoned” after 180 days, so the government can request them without a warrant.) This includes inbox contents, metadata, IP addresses, and more. and may be forced by law to turn over information on its users. Switzerland is not part of the Five Eyes intelligence-sharing agreement that exists between the U.S., Canada, Australia, the United Kingdom, and New Zealand.īy comparison, Google is located in the U.S.

This means that ProtonMail can’t be forced to hand over data to authorities in the U.S. In addition to not being able to read the email stored on their servers, ProtonMail is based in Switzerland, where privacy laws are notoriously strict.

Unlike with ProtonMail, which explicitly supports the feature, working with PGP inside of Gmail is much less streamlined and borderline unusable on mobile. Using PGP inside of Gmail is possible but difficult, with browser extensions like Mailvelope and FlowCrypt making it easier to manage.
