What it entails

Network Intelligence Checks monitor email longevity and activity via first_seen and last_seen, phone longevity via first_seen, and flag never-seen or disposable email addresses. They build a holistic maturity and legitimacy score for email addresses and phone numbers.

Why it works

Fraudsters spin up newly created, disposable, or invalid emails or phone numbers to evade linkage and detection.
