The Proofpoint TAP (Targeted Attack Protection) module is capable of intercepting, blocking or executing mail as SPAM or phishing-emails in a test environment. Insufficient setup can lead to errors in sending or reporting.
If you have Proofpoint TAP in use, please log in to the Proofpoint internal support area and search for the article
"[Email Protection] Best Practices for Using a Third Party Anti-Phishing Vendor to Test Employees".
There you should find all the information you need to approve Proofpoint's TAP for our simulation.
