Risk Score

What is the Risk Score?

The Fideo Risk Score is a normalized value from 0.0 (lowest risk) to 1.0 (highest risk), reflecting how well the input payload maps into our identity graph and passes our Verify Checks. Supplying richer identifiers (e.g. name + address + email + phone) yields more reliable scores than minimal inputs (e.g. name + email).

What Feeds In to the Risk Score?

1. Data Validity

   • Format checks (email syntax, phone format, address parsing)
   • Liveness checks (MX/Telnet probes, address verification)

2. Graph Connectivity

   • Coherence of your attributes in our graph (how tightly they cluster)
   • Depth of linkages (number of hops to known entities)

3. Coverage & Uniqueness

   • Volume of historical observations for each identifier
   • Uniqueness signals (shared vs. rare values across graph)

4. Usage Characteristics

   • Device & network reputation (IP risk, device fingerprint)
   • Behavioral anomalies (velocity, geo-velocity, session patterns)
   • Credential checks (breach list, compromised status)

These signals are weighted dynamically based on context and use-case.

Global Watch Scoring

The OFAC person and organization, UN, EU, UK, Canada, CSL, FBI Wanted List, and PEP candidate checks share one contribution to the risk score. Only the highest-risk check in this group contributes; every individual check and its risk remain visible in the response.

PEP candidate matches have LOW risk, whether they match by name alone or by name and location. The other Global Watch checks use MED for name-only matches and HIGH for name-and-location matches.

NO_MATCH, UNKNOWN, and NONE have risk NONE and add no risk to the score. Their meanings differ: screening completed with no match, screening unavailable, or no eligible input, respectively. Consumers should inspect the check state when deciding whether screening requirements were met. See Global Watch Checks.
