Network Share Protection - Limit writing to domain-only endpoints

Dear All,

is there a way to prevent enpoints that are managed by McAfee DLP from writing to any SMB/CIFS shares that are hosted by endpoints that are not members of our domain? 

I checked out the Network Share Protection rule page and it seems to exclusively use lists of named shares. This seems a very unwieldy way to restrict data motion over SMB to the space of the company network, which is exactly what we would like to do. 

Thank you very much in advance!

No, It's not possible to BLOCK access to SMB shares by using Network Share Protection rule.

In the Network Share Protection rule reaction you see there even dont have an "Block" reaction, can only Monitor.

Hi @FA1 ,

As already communicated in the other post, it is not possible to block Network Shares using DLP,

You have only three Reactions,

No Action


Request Justification 


You can Monior any network share or encrypt data written into these network shares, however we will not be able to block the Network Shares in total as per the product design.
