Although there is no perfect security for content delivered online, we offer a number of tools to help you.
First of all, major document types (PPT/PDF/DOC) are converted to a non downloadble format. Users may see the content online but they cannot download it as one entity. You need to explicitly share a file for a user to be able to download it (from course > files)
All embeded files use an expiration timestamp. This means that if someone shares the URL to one of your shared files this will expire after 2 hours. The URL becomes invalid after that time window.
For videos we offer watermark-based protection. This let you embed your logo directly on your videos through our conversion service. This watermark cannot be removed from your videos.
In order to enable this option, move to the Account&settings as an Admin, visit the Security section and check this option (1).
Note: The watermark is being added during the conversion of our transcoding service so make sure the "Disable video transcoding service" box is not ticked.
