TEODEX helps you to build your own secure, hybrid end-to-end encrypted network on your smartphone and on your computer

Strong military encryption without "back door" ensures that no one can listen, read or can steal any data.

  • With TEODEX the entire communication is hybrid end-to-end encrypted
  • TEODEX does not collect any data
  • IF security will be "merchandise"

    Many companies promise security with secure software solutions, such as encrypted telephony apps or end-to-end encrypted messenger apps.

    Unfortunately, this promise is not held to 95%. What is the advantage of an encryption software, if the telephone conversation as well as data are tapped before the encryption works on the smartphone.

    Telecom companies have maby a little or no interest, like smartphone manufacturers, to make your data exchange safe, their business plans are quite different, they are only interested in selling smartphones and conversation rates.

    With security software solutions that often runs into the empty, they will covered only a "need" in order to expand their own portfolio of products.

    This has very little to do with real security.

With the help of the German Trojan, the contents should, for example, be a short message before the encryption can be viewed and sent to the authorities. Somehow this sounds like Fake News. Short messages can be tapped before encrypting is already today possible without (German Bundestrojaner). But that a new gate is opened by a (German Bundestrojaner) for every hacker is new and actually the opposite of save.
