I use it for over 10 years now. First installed it around 2012 and still does the job for me very well. Many options, well built and complex system for sharing documents and not only.

Secure Filesharing, customers love it - i love it!

Open source tool makes it accessible to all the people. Simple and easy to use user interface. Easy to add users, configure notifications to mails. The application is available for web deployment and app is available for all major mobile operating systems. Easy to allocate storage user wise. You can login and add (or drag drop) files and share to any user present in the network. It just does have all features required for secure file sharing.
