Detect specific credit cards - DLP

[Christopher Campos]

Hello, is it possible with DLP to detect specific credit cards starting with a specific number?
For example, alert only when transmitting information of cards starting with: 5559

5559-xxxx-xxxx-xxxx-xxxx

Thank you!

That's not really a use case for DLP, but you should be able to address it by creating a custom sensitive info type: https://docs.microsoft.com/en-us/microsoft-365/compliance/create-a-custom-sensitive-information-type...

I thought of that first, but apparently it is not possible as I had thought. Thanks Vasil.
