With fraud detection outsourcing, a business can use an external team to review suspicious activity and support its internal fraud prevention processes. I’d want to know how alerts are generated, how cases are investigated and how serious issues are escalated. Data security and access controls are also important because fraud teams may work with sensitive customer and transaction information. Another thing to consider is how the provider communicates with the internal team when a case needs further investigation. A well-defined workflow can prevent alerts from becoming lost between different departments.
