Tutanota 将负责保护邮件安全的源代码公开发布以便安全专家审核。我们的 Android 应用也断绝了与 Google 的关联，使得 Tutanota 成为最佳的开源邮箱服务。
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 Tutanota. I myself like working with Tutanota because it is easy to use and I know that communication here is in good hands.
Dr. Frank Hülsberg, Warth & Klein Grant Thornton AG
We chose Tutanota as a "secure by design" email provider. Due to its encryption Tutanota fully complies with GDPR requirements, which makes it perfect for business use. Tutanota is fast, reliable, always up-to-date and meets our needs. All of our clients' industrial confidential information is kept secure.
Michalis Apostolou, EPD Engineering Services
In a very sensitive business environment, we have chosen Tutanota among various encryption programs. Tutanota 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.
