Question: How can I prevent users from creating multiple accounts to take advantage of referral and promo offers on my platform?

One is SHIELD. This AI-based device fingerprinting service is designed to block fake accounts, thwart account takeovers and spot referral and promo abuse. SHIELD's Device-First Risk AI approach offers a persistent and accurate way to identify users and devices, making it a good choice for online businesses.

Another is Incognia. This identity service offers persistent device fingerprinting and indoor location intelligence to block fraud and ensure a safe digital journey. It's good for blocking account takeover and promo abuse, for example, and features such as user verification and listing verification can cut down on false positives and provide a frictionless user experience.

For a broader fraud detection and prevention service, check out Verisoul. Verisoul automates manual processes and consolidates vendors so you can stay a step ahead of fraudsters. It assesses a broad range of signals including device risk, proxy and VPN detection, account linking and bot detection to ensure that every user is real and unique. That can help you block repeat sign-ups and other fraud.
