Tuta gives your company privacy

The world’s first post-quantum encryption for email

Tuta began already in 2014 as the very first email provider to automatically encrypt emails, and this year launched the world’s first quantum-safe encryption for email. As Tuta grows, we are constantly improving our secure email platform to deliver the most secure end-to-end encrypted protocols to keep your business data secure, now and in the future.

As the world’s only email provider offering post-quantum encryption for email, your business data is guaranteed full privacy.

As the world’s only email provider offering post-quantum encryption for email, your business data is guaranteed full privacy.

Tuta aims to encrypt as much as possible and it is the email provider encrypting more data than any other email service available. This includes an end-to-end encrypted mailbox, calendar and address book. Because the data is end-to-end encrypted by default, your organization’s communications and confidential data is secure from being exposed.

Zero-knowledge architecture ensures data is stored encrypted

With Tuta’s zero-knowledge architecture your company data is stored encrypted on its servers based in Germany – the data is not stored as plain text. In addition to this, only the Tuta user has the decryption key. This guarantees that if your internet connection gets intercepted or in a highly unlikely case that Tuta’s servers were hacked, your comapny’s data is still secure and inaccessible. With Tuta, only you, the intended user, can decrypt the data; no one else has access.

Why all companies need end-to-end encryption

Companies need to use end-to-end encryption to ensure their email communications remain secure from any third party. End-to-end encryption is the most secure way to send emails from the sender to the recipient. With end-to-end encryption, only the email sender and intended recipient hold the keys – allowing them to encrypt and decrypt the email. Because of this, no one, not even Tuta as the email provider can access the contents of the email.

In short, end-to-end encryption ensures your emails are sent in a locked vault, and only when the person with the key unlocks it, is the contents available.

Through using Tuta encryption you are guaranteed that your email communications stay confidential and protected. Security and data sovereignty are therefore the main reasons why a company should use end-to-end encryption.

Send password-protected emails to anyone

Tuta let’s you send password protected emails easily, to anyone.

Tuta allows you to send end-to-end encrypted emails to any recipient regardless of their email provider through the use of a password.

Watch on YouTube how easily you can encrypt emails to anybody.

Tuta allows you to send password-protected emails with end-to-end encryption easily. With Tuta, email users can send end-to-end encrypted emails to anyone – regardless of their email provider. This is done through a shared password which can derive the decryption key for your recipient to view the contents of the email. Through this encryption feature, even if you need to send a confidential email to someone who uses a popular email provider like Gmail or Outlook, there is a simple and efficient way to encrypt and decrypt the email for the sender and recipient.

No tracking, ads, or IP logging

Big tech email providers don’t make their profit with their email product itself – they profit by tracking you and posting targeted ads. Tuta is quite the opposite - it does not make its profits off advertising. This means that we do not track you, and we do not scan your emails.

It’s impossible for Tuta or anyone to access your email due to our end-to-end encryption. And of course, along with that we never target you with ads. With Tuta, none of your data is used for advertising purposes, and we never share any data with third parties. In addition to this, we do not log IP addresses of how our users are connecting to their Tuta accounts.

Tuta allows you and your company to enjoy private and secure email with no added baggage.

Tuta ensures security

Security First

As an email provider that places privacy and security first, Tuta ensures the highest security standards.

  • Tuta does not use PGP. Instead, Tuta has developed the encryption so that we are able to encrypt more data than PGP: metadata such as subject lines, attachments in emails, inbox rules, the locally built search index, as well as other products such as Tuta Calendars and Tuta Contacts - everything is fully encrypted end-to-end.

  • Tuta does not search through user data on the server; never. Tuta has created a system that builds an encrypted search index that is stored locally on the user’s device and searched there. Through this built an encrypted search index, you can easily search your entire mailbox in true privacy.

  • Tuta does not offer IMAP. If we offered IMAP, we would need to send and store decrypted data to your device which we consider to be a security risk. This is why Tuta offers open source desktop clients and mobile apps that store your data fully encrypted, best of all these apps are available completely free of cost.

Maximum login protection for your workforce

Tuta is unable to access user passwords and login credentials: Every time you log in to your account, Tuta uses a salt and a hash to transmit this hash of the password to the servers for authentication. This means that nobody, not even we at Tuta, can deduce the passwords of the users from the hash. As an account administrator for your team you can reset the login credentials of team members in the event that they forget their passwords.

To take the login security of your company mail up a notch we also support two-factor authentication (2FA). To maximize login security, Tuta users can use TOTP authenticator apps or U2F hardware keys.

Tuta recommends using U2F with a security key as they are currently the most secure means of two-factor authentication available on the market.

Open source code

Due to a strong focus on privacy and security, Tuta’s web client, desktop clients as well as the Android and iOS apps code is open source and released on GitHub. Through open source publishing, we can provide true transparency and anyone is able to check the code verifying there are no bugs, backdoors, or vulnerabilities. As an open source company, any issues are noticed and addressed quickly.

Usability for everyone

Encryption made easy

Other email providers who offer end-to-end encryption often come with a complex set up that wastes valuable employee time. In addition to this, providers make sending an end-to-end encrypted email a complex process – thus affecting productivity and usability for a workforce. Tuta wants everyone to be able to use end-to-end encryption by default. With Tuta, you can write your email and send it without any extra steps – all with the guarantee of end-to-end encryption. With Tuta’s easy to use interface, sending private emails is easy! Even for those with little tech experience.
