In the course of our activities, there are also particularly confidential communications that must run outside our own domain. We asked our IT security experts to carry out an evaluation of the providers and they chose Tuta. I myself like working with Tuta because it is easy to use and I know that communication here is in good hands.

Consultancy

We chose Tuta as a "secure by design" email provider. Due to its encryption Tuta fully complies with GDPR requirements, which makes it perfect for business use. Tuta is fast, reliable, always up-to-date and meets our needs. All of our clients' industrial confidential information is kept secure.

In a very sensitive business environment, we have chosen Tuta among various encryption programs. Tuta impresses with its extremely simple application. Even non-technical colleagues can encrypt sensitive attachments and texts in accordance with data protection regulations. The simple administration, immediately accessible & always friendly experts and a fair pricing also stand out.

Join the encrypted side and you’ll never look back!

Protection from current cyber threats...

We use implementations of AES 256 / RSA 2048 algorithms which, unlike PGP, enable us to encrypt E2E more data than any other email or calendar provider: entire emails, including subject lines, attachments, email bodies, entire address book (not just parts of the contacts), inbox rules and filters, the entire search index, and all calendar entries, even metadata like who is attending a calendar event.

With any Tuta Business plan you get an unlimited number of calendars and the possibility to share calendars to easily coordinate with different teams in your organization. Ours is the only zero-knowledge calendar, because our servers don’t even see when you get a push notification for an upcoming event. Instead of sending push from our servers we handle encrypted notifications directly on your device to protect your privacy. With the mobile apps you also receive these reminders when you are not actively using the app.

When you also add login protection, session handling, two-factor authentication (2FA) including support for U2F hardware keys, biometrics unlock on mobile, and our zero-knowledge architecture, you get the best email service for businesses and professionals who value data security.

...and from future cyber threats

When you sign up for Tuta, you’re protecting your business from current as well as evolving and future cyber threats.

We publish the Tuta web client, the Tuta desktop clients as well as the Android and iOS apps as open source software on GitHub, so on top of regular security audits from independent experts, everyone can check that there are no bugs, backdoors, or security vulnerabilities. This means potential issues can be noticed and fixed much faster than with closed source applications.

Tuta is also ahead of the game in terms of post-quantum security and Perfect Forward Secrecy. We have a working prototype capable of post-quantum secure encryption and in the near future all Tuta clients will have the same capabilities to protect your data from future attacks from quantum computers.

The encryption protocols that we use in Tuta enable us to easily update the algorithms. After the update, the migration to the new algorithms is seamless, so you will benefit of the added security immediately and without any hassle.
