SentiLink

Overview

SentiLink, founded in 2017, specializes in synthetic and identity fraud detection for US financial institutions, providing risk scores and insights on applications and SSNs. It is a focused risk specialist rather than a full verification suite. See all identity verification vendors for alternatives.

What it is good at

Deep US synthetic-fraud expertise is the strength, with high-signal risk scores that flag fabricated and manipulated identities other tools miss. The narrow focus means strong models, clear application-level insights, and a product built specifically for the US lending and fintech fraud problem. Its scores are designed to slot into an existing decisioning flow as an added signal, and the insights explain why an application looks synthetic, which helps analysts act rather than just receive a number.

Where it falls short

SentiLink is US-focused and specialized, so it complements rather than replaces a full verification stack: there is no global coverage and no full document-verification suite. Teams needing international onboarding or document and biometric checks will use it alongside other vendors, and pricing is quote-based. Because it does not capture or verify documents itself, it is always one component of a stack, and buyers must integrate it alongside a primary verification vendor.

Best for, and who should look elsewhere

Choose SentiLink when you are a US financial institution fighting synthetic and identity fraud and want specialized risk scores. Pair it with document verification from Onfido; for broader fraud and device signals consider Sardine; for deep identity data consider LexisNexis Risk Solutions.

Bottom line

A strong specialist for synthetic and identity fraud in US financial services, used alongside a verification stack.
