Why your organization needs a secure file exchange solution

It is impossible to imagine our work processes without digital files. While some industries 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 it contains is also easily accessible. In addition, there is also plenty of software available that focuses on sending large files.  However, if we look more closely at this, we see that these services often do not comply with the applicable regulations. 

secure sharing

Why you should share large files via email:

  • Speed
    After sending, the recipient receives the files in no time. This will not only save your organization a lot of time but will also increase productivity.
  • Security
    Thanks to zero-knowledge end-to-end encryption, only the authenticated recipient has access to your files - entirely in accordance with the guidelines of the GDPR.
  • Efficiency
    Files can be sent any time of the day, regardless of the time or location of both the sender and recipient.
  •   Overview in the sent files
    Files sent by email can easily be seen in the sent items. This way you keep an overview of all mail traffic and you can always see which files have been sent and to whom.
  •   Stay in Control of Your Sent Files
    When sending large files by mail, there are security options that can retract incorrectly sent files. This includes files that have been accidentally sent to the wrong person and could potentially lead to a data breach.

What is the maximum size when sending large files by email?

  • Outlook: Maximum of 10MB for free accounts and 25MB for paid accounts.
  • Gmail: Maximum of 25MB.
  • G Suite: Maximum of 25MB. For larger files, it is recommended to use Google Drive
  • Yahoo: Maximum of 25MB, which applies to both the email message and the attachment.

This is what makes free services like WeTransfer and Dropbox unsafe

Email_beveiligd_groen-1

We probably all know them: services such as WeTransfer and Dropbox with which large files can be exchanged. Files up to 20G can be shared via their 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.

These functionalities assist in the secure transmission of large files


We want to be able to share files securely and easily. But, how exactly does that work and what helps? When choosing a solution that makes it possible to send large files, these functions include:

  • File limit that exceeds the average file size of an email client.
  • The ability to request specific file sizes and types so that you immediately receive the correct files. In a safe way!
  • An extra check on files before the email is sent.
  • Uploadportals where files can be easily uploaded, where files end up directly with the right people / departments.
  • Zero-knowledge end-to-end encryption
