Sophos XG block uploading files with exceptions

Hi TimusAtko,

Thank you for reaching out to Sophos Community.

Refer to the article below to block Browser-based upload/file transfer.

Thanks for the suggestion, I've been through the setup process in the KB and specifically blocked SharePoint for the application filter. I then created a firewall rule using the application filter with exclusions if the SharePoint URL matches my companies SharePoint URL but it doesn't block uploading to external companies SharePoint. Is what I'm trying to do possible? If it is, what's the best way to achieve this?

In short I've been asked if I can block people from uploading to other companies SharePoint/OneDrive sites without affecting our own.

Hi,

please post an expanded copy of your rule and policy. I expect you will need to amend your rule so that the WAN network is limited to your companies site.

App Filter:

Thank you.

Suggestions

1/. remove your excluclusion list

2/. change your destination network to your companies website

3/. change web policy to allow all.
