Behavioral risk score
Also known as: Behavioral score · Behavior-based risk score
A risk score built from how a person behaves — mobility, stability, ties and usage — rather than only from the credit history they happen to have accumulated.

A FICO or VantageScore answers a question about the past: how this person handled credit. A behavioral score answers a different one: how they act now. Those are not the same question, and the second is the one that predicts loss and default in people whose bureau file is thin, stale or empty.
In practice that means reading signals the three nationwide bureaus do not collect — movement patterns, stability, consistency between the identities a person presents, ties to other records. Zarv ID composes over 200 such sources and returns a result in under 150ms at 87% accuracy, which is what makes it usable inside the approval flow rather than in a report someone reads later.
It is worth separating this from a homonym. "Behavioral" also describes behavioral biometrics — typing rhythm, cursor movement, device signals — read during a session to catch a bot or an account takeover. That signal lasts seconds. The behavior Zarv ID reads is physical and lasts the whole contract: where someone moves, what ties they hold, how they use the asset.
Where a behavioral score feeds a US credit decision, it inherits the same duties as any other model under the Equal Credit Opportunity Act: a declined applicant is owed the specific reasons, not the score. Behavior is observable from day one, and it has to be explainable too.
Frequently asked questions
What is the difference between a behavioral score and a credit score?
A credit score is computed from credit report data: payment history, balances, account age and inquiries. A behavioral score adds signals about how a person acts outside credit, such as mobility, stability and ties, so it can also describe people with little or no credit history.
