Sending large files

Convenient transfer of large files.

Sending large files securely – without restrictions via email.

Sending large files can be a challenge if data security is the top priority. Most commercial filesharing services for sending large amounts of data do not provide encrypted data transmission. This leaves your large files open to avoidable security risks, which can be business-critical, especially for companies and authorities. Whether high-resolution video files, 3D animations, complex design data, presentations or else the results of imaging procedures. When sending large files, every email program immediately reaches its limits.

As an alternative to sending large files, companies often resort to FTP solutions. However, these are complex to set up and use. Some therefore use free filesharing services. What both tools have in common is that they are not secure. Data is sent unencrypted or the server is in regions without legal data protection. A makeshift solution therefore turns into a security risk.
