DLP Policy to detect First/Last name

Hi Everyone, 

 

I have the following requirement:

 

To implement a DLP policy to monitor and trigger an incident for the following:

" First or Last name + Phone Number OR Email address OR Postal Code " 

 

Unfortunately, there is no database or structured data available for indexing via EDM. This contacts could be exported via Outlook or Salesforce etc.. by users and then sent out via email or webmail... 

The challenge is that there is no real pattern for detecting First/Last name...

 

What is the best practice to implement a DLP policy in this situation to avoid many false positives ?

Creating IDM or DCM (Regular Expressions) ? Is there anything built-in within Symantec DLP solution that can tackle with the problem of detecting First/Last name ?  

 

Thanks in advance.
