Send large files - easily and securely

Make sure that your documents only arrive at the intended recipient.
Everything you need to know to securely exchange files can be found here.

The sending of files is indispensable in our work processes. Where some branches prefer to work with USB sticks, this is a no-go for many organizations. The loss of such a stick can have major consequences if the information on it is also easily accessible. In addition, there is also plenty of software available that focuses on sending large files. But if we take a closer look, we will see that these services often do not comply with the applicable regulations.

Why free services like WeTransfer and Dropbox are not safe

We probably all know them: services such as WeTransfer and Dropbox with which large files can be exchanged. The concept is simple and does what it promises. Files up to 20G can be selected via the website, after which the recipient receives an email with the files. Simple? Yes. Fast? Also. Safe? No! We have listed the most important points for you:

  1. No end-to-end encryption, so the files are not sent securely. If these were intercepted during shipment, information could be accessible to unauthorized persons.
  2. No strong security option such as two-factor authentication
  3. No check on the sent files, so any wrongly selected files would not be noticed.
  4. Wrongly sent files cannot be blocked afterwards.
