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.
