Tuta (formerly Tutanota) protected email service

Tuta, originally launched as Tutanota in 2011, is a pioneer in the secure communication sector. The service was founded by three developers in Hanover, Germany, who sought to create a privacy-first alternative to mainstream email providers. The core philosophy of the brand centers around end-to-end encryption, ensuring that only the sender and recipient can read the contents of a message.

While traditional software products have a manufacturing origin, Tuta’s 'manufacturing' consists of its software development and server management, all of which are based in Germany. This location is strategically chosen due to Germany's strict privacy laws (Federal Data Protection Act and GDPR). The brand underwent a significant rebranding from Tutanota to Tuta in late 2023 to represent its growth into a broader secure productivity suite including encrypted calendars and contacts. To this day, the company remains independently owned by its founders, resisting venture capital influence to maintain its commitment to user privacy.
