Just asked support for this feature to prevent unauthorised downloads of our IPR content and was sent here.
Like others, we use this feature with Docsend and want to move to using Hubspot documents instead.
Without this feature though, prospects are able to download content and share it with competitors (which we can’t allow) and we also lose the ability to track opens, reads, capture emails, etc. when they share it elsewhere.
We also lose the capability to control the period of time they are able to view it. This is essential to retract commercially sensitive proposals and presentations when we have lost the project to someone else. Of course, when documents are downloaded without our consent, we have no way of controlling this. Our documents contain commercial notices disallowing this sharing without permission but we can’t stop it or know when someone has broken trust.
In our view, this feature is therefore essential.
