SOFiE - Safe Online File Exchange

The SOFiE application is designed for the safe exchange of files of any size and type. It offers a top-level of security for sending and receiving files, both within your company and when communicating with external partners. The protection and security of data in the SOFiE application achieve a level that cannot be reached by regular use of email, FTP servers, or public cloud services. At the same time, the application provides a simple and comfortable interface for users. In other words, SOFiE is the best and safe way to exchange files online, including sensitive information, and sets a new standard for security and convenience in digital communication.

Why do you need the SOFiE application?

  • You need an easy way to send or receive files that are too large for email.
  • You want maximum assurance that the files you receive are safe and do not contain viruses or other malicious code.
  • You cannot afford to upload your files with sensitive data to the cloud, where you would lose full control over them.
  • Your users desire a simple web interface that is easy to use.
  • You require detailed logs with an audit of all transfers, actions, and events.

If one or more of these points describe your needs, the SOFiE application is the right solution for you.

Full Control Over Data

Unlike publicly available data sharing services, SOFiE allows you to maintain full control over your uploaded data and files. The application can be deployed in your own environment on your own infrastructure. This way, you do not face the risk of entrusting your sensitive files to a third party.

The Application Includes Detailed Activity Auditing

SOFiE contains a detailed audit log of all actions and processes within the application, including user logins, sending, and receiving files. These logs can be sent to a central syslog or SIEM.

Compliant with NÚKIB recommendations

SOFiE includes security technologies and processes that help fulfill the recommendations for administrators.

Main features

Integrated file protection Integrated file protection using anti-virus engines and Sandboxes, which detect even Zero-Day threats.
Clientless solution Clientless solution - users need only a web browser (no plugins or other software required for clients).
Adjustable file lifetime Adjustable file lifetime (automatic removal of files based on a user's or administrator's setting).
Encryption at rest Support for encrypting files in the application store - "encryption at rest".
API The application includes an API for integration into third-party applications.
Data integrity checks Support for one-time and regular data integrity checks to detect possible file corruption.

Problems with e-mail attachments

Attachment size problem

Most e-mail servers limit the size of attachments to less than a 50 MB (often even 5 MB or 10 MB). E-mail communication is therefore not suitable for exchange of large files, which often exceed these size limits for attachments.

Attachment blocking problem

The security nowadays often requires using highly restrictive policies for attachments allowed in e-mails. Such policies for example block executable files, documents containing macros and even archives containing such files.


The SOFiE application enables you to safely send and receive files, which are problematic in e-mail communication.
