One-time screening, sometimes called prescreening, is a single check on a person or company at the point where you need to make a decision. Before you onboard a customer, sign a supplier, close a deal or make a hire, you run their name against sanctions, PEP, ownership, adverse media and other risk sources, and get a clear picture of who they are and what risk they bring. It’s the quick “should we go ahead?” check. Everything you need to clear a party, in one go, without collecting a single document.
