SOFiE - Safe Online File Exchange

It is our pleasure to present to you SOFiE - a simple application solution for sharing your files of any size and format. SOFiE provides maximum security for receiving and sending files between you and your clients or suppliers. This application will significantly increase your protection to a level not provided by a traditional e-mail or FTP server. Simply put, SOFiE is the most secure way to share sensitive information online.

Maximum security is the main priority for SOFiE. Therefore, you can be sure, that all your files are automatically checked using advanced anti-virus scanning techniques. If you are interested in an even higher level of security, we can offer an integrated interface that allows you to verify the uploaded files via sandboxing. This technology is able to detect even the most advanced threats and zero-day attacks. All files are transferred through encrypted channels, of course.

The SOFiE application corresponds to the recommendations

SOFiE will allow you to retain complete control over your shared data and files which is a key difference between it and other similar public services available on the Internet. You can have the SOFiE application installed in your own IT environment or own cloud. This mode of operation avoids the risk of entrusting your sensitive files to an unknown, unverified and potentially dangerous third party. You no longer have to use physical media like USB flash drives for data transfer. SOFiE application offers data exchange in compliance with the GDPR and it does so in user-friendly, controlled and safe way.

GDPR Compliant

SOFiE stores audit logs of all activities, including user log in, log out, file upload, file download and others. Such logs are important for compliance with regulations, forensic analysis, litigations and other issues (application reflects GDPR requirements).

Safe sending of large files

Most e-mail servers limit the maximum size of messages to less than 50 MB (usually even 5 MB or 10 MB). When sharing data, the speed of the communication often plays a key role. Therefore, common e-mail communication with message size limits can negatively impact the effectivity of cooperation with your colleagues or business partners.

SOFiE is the solution for secure transfer of large files - the size of shared content is not limited. However, as an administrator, you can configure the maximum size of files to be exchanged.
