Verify Checks Overview

Fideo Intelligence’s Verify Checks provide a unified framework for assessing the authenticity and risk of a digital identity. By combining dozens of specialized signals—ranging from data‐breach monitoring to IP geolocation consistency—our platform empowers organizations to stand up robust identity verification flows and stop fraud before it happens.

Use Cases

Pre-KYC Synthetic Identity Screening

Catch fabricated identities at the very start of your onboarding funnel—before you spend time or budget on KYC/AML checks. By running name, address, email, phone and device/IP mismatch checks in real time, you can halt synthetic profiles instantly and focus your manual review on genuine applicants.

Online Account Opening (OAO)

Deliver a frictionless, secure digital account opening experience for banks and credit unions. Fideo’s Email, Phone, IP and Digital footprint checks verify that each applicant’s contact and network signals align with expected behavior—blocking disposable emails, burner phones and anonymizer proxies without customer drop-off.

Loan Origination

Accelerate decisioning on loan applications by embedding Verify Checks into your pre-qualification workflow. Breach and sanctions screenings surface compromised or blacklisted identities, while longevity and activity metrics on email/phone reduce default risk—helping lenders underwrite faster, smarter, and safer.

Digital Onboarding for Banks & Credit Unions

From retail banking to credit union member acquisition, our full suite of check packages provides a unified risk score that supports CIP, CDD and regulatory compliance. By orchestration of Synthetic Identity, Breached, Location and Identity sanctions checks, Fideo reduces fraud losses, slashes manual reviews, and delivers a superior customer experience.
