I was not able to find event source configuration guide for integrating Proofpoint TAP dashboard in RSA Netwitness documents.
I've moved your question to the RSA NetWitness Platform space where it will be seen by the product's support engineers, other customers and partners. Please bookmark this page and use it when you have product-specific questions.
Alternatively, from the RSA Support page, click on Ask A Question on the blue navigation bar and choose Ask A Product Related Question. From there, scroll to RSA NetWitness Platform and click Ask A Question. That way your question will appear in the correct space.
If you are looking to send events into Netwitness, we currently do not support the ProofPoint TAP. Please see post: https://community.rsa.com/thread/200602
