Qabel
Qabel is a free, published-source cryptography platform. Where others retroactively install encryption in existing services such as Cloud, e-Mail or Messenger, Qabel does it entirely the other way round: the platform encrypts everything that is connected with it end-to-end, including Messenger, e-mail, industrial applications and individual solutions. As a user, you only have to deal once with encryption across application and can then exchange end-to-end encrypted data within applications connected to the platform. Moreover Qabel ensures that metadata is largely obfuscated. Until now, the market has offered a lot of application-driven software that promises security. In existing individual applications like messaging, cloud and e-mail, encryption is installed later. The disadvantage: as a user, you have to configure each application separately. That is complicated and tedious and massively hinders the distribution of a standardised system.
