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 GMX-Mail. I myself like working with GMX-Mail 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 GMX-Mail as a "secure by design" email provider. Due to its encryption GMX-Mail fully complies with GDPR requirements, which makes it perfect for business use. GMX-Mail 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 GMX-Mail among various encryption programs. GMX-Mail 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.
