Retarus LFiX - Large File Exchange

Web-based platform for secure exchange of large files with defined communication partners

No size restrictions, reduced loads

Do you often have problems when sending large files by email? Is your email system sometimes unable to cope with this load, and are you prevented from sending important business data because the size restriction set in your email environment does not allow this? If so, LFiX is just what you are looking for!

In order to bypass file size restrictions and/or reduce the load on email systems, for example, Retarus offers its customers an HTTP-based solution, including user management, for uploading and downloading large files.

No hardware. No software. No problems.

Have a web browser? Good. That’s all you need. We provide the equipment for the application – including web server, virus scanner, and Retarus SSL certificate. Our user-friendly application is completely web-based and independent of your email system.

How LFiX works:

File transfer takes place securely via HTTPS (SSL).
Files can be simply uploaded onto the Retarus server and the intended recipients are then informed by email. This email contains a specific URL from which the recipients can download all files intended for them after successful authentication. All files uploaded to the Retarus LFiX environment are automatically checked for viruses. In addition, senders can view a list of all sent files. Your benefit: a complete overview of file transfer, including receipt confirmations.

Individual web interface design

Customize Retarus LFiX to fit your needs. The web interface can be configured to match your preferred design. You can also manage the access rights of the users, ensuring your data stays in good hands.
