The secure file sharing is easy even over mobile devices as it does not require an app download like other similar services that I have used in past years (iCloud/Dropbox). We were able to use our own storage instead of relying upon someone else's servers for large files such as images which are important from us being able to deliver great service to clients but also saving costs too! Not all features work straight away when first setting up - some users had issues when they couldnt get access via password protected links etc- we solved this by re configuring permissions with administrators at client end after initial set ups where done correctly.- overall very stable system once working well and no complaints about performance levels either at time of writing my blog post today.
