A TransRisk score is not an actual FICO based score. Instead, it is simply a consumer credit score marketed by TransUnion on its www.transunioncs.com website.
The TransRisk score is different from the TransUnion score, which is marketed at www.transunion.com. It is also not FICO based.
The credit scoring product that TransUnion provides to lenders is known as the Empirica score.
