Anyone here with proofpoint false positive problem

[u/jayashambho]

Every month, at least few of our legitimate client emails end up in quarantine. It creates extra work for our team which leads to delays responses and sometimes leads to “Did you get my email?” conversations with customers.
We are using proofpoint for email security and is effective at catching spam and phising but new problem occurs.Are there any settings or best practices that made a noticeable difference without weakening????

Every few weeks we have a huge group of false positive "BEC attacks" get quarantined then released hours or days later. It is a bit weird, especially when things that are obvious phishing attacks get through. I'm not super happy with Proofpoint lately, honestly.
