Hi @KiranBashyal what kind of sharing are you referring to? Is it file sharing over SMB or uploading files to WF? As you are aware, Cortex XDR manages endpoint protection of malicious behavior. If you're looking at volume quotas, that should be an operating system specific control that are centrally managed by existing solutions.

Sharing of files from endpoint to endpoint, Endpoints cud be on same network or different network. Simply the sharing should contain the size restriction. i.e upto 500mb of any files can be shared from certain endpoint

 

Hi Kiran, it is not possible to restrict such features OOB.

However, there are Analytics detectors to raise alerts of such a nature. Here's an example for HTTPS (https://docs.paloaltonetworks.com/cortex/cortex-xdr/cortex-xdr-analytics-alert-reference/cortex-xdr-...)

 

You can also use the network_story preset to query for upload sizes and convert it into a BIOC for alerting. Look at the field action_total_upload.
