regex in DLP for Sharepoint, drive, one drive

[GSecurity]

Hi everyone,

I'm digging a little deeper into policies for collaborative tools, I was wondering if it was possible to detect when a user publicly shares a file with external domains. I figured I could do this with DLP rules using regular expressions (REGEX), the problem is that I can't find these options.

Please kindly help me

Thank you

Hi @GSecurity 

If I understood correctly, you want to classify the data using REGEX and implement it into a rule.

The rule direction is "to internet" (you will need HTTPs Inspection implemented, to get DLP work correctly)

R81.20_DataLossPrevention_AdminGuide

Fine Tuning- > Add data types to rules -> Adding Data Types to Rules

Maybe are you looking for this option?
