Allow individual users to be able to download certain extensions from individual websites
We would like to be able to allow individual or a group of users to be able to download a file type from a certain website only.
for example if ZIP files are blocked from being downloaded, however we have three users that often download from dropbox. We would like to allow these three users to be able to download ZIP files from dropbox only.
receiving here a lot of customer requests about this as well: to be able to tag a particular site to allow the download of certain (and generally blocked!) filetype just from this site, would highly be appreciated and a very handy feature!

The issue we have with Docx and alike file types is sometimes they are detected as ZIP files. I am reluctant to open ZIP files for
The workaround is to make that particular site 'trusted', which allows all file types and disables scanning.
Ideally we would be able to have a custom property for the particular site so we can only open ZIP files and keep other extensions
blocked. Trusted opens up far too many potential vulnerabilities for us.

Agreed, with the increase in more OPEN type of usage policies for URL category access; businesses still wish to regulate what file types can be downloaded from these sites.
Ideally, breaking the association of URL and File Type within default and Additional rules and having file types act in a similar fashion to that of how the newer Authentication/Connection Profile system works would allow an overlay of file type downloads depending on request and or destination.
This would also mean a rework of the User Submission for FILES as well due to its current design.
I've also received queries on this with customers that would like specific users only to be able to download large or encrypted files.
One customer requested the ability to allow ZIP files from only certain categories of website. More generally, the ability to set policy for file types based on site category and/or site tag has been requested a few times in the past.
