ShieldLabs

ShieldLabs is fraud detection and prevention with traffic quality scoring. It detects users running multiple accounts, account sharing and takeovers under any masking, so you prevent losses from free-trial, bonus, promo and API abuse.

What it does

• Visitor and user identification. Recognises returning visitors across sessions, after cleared cookies and through IP changes, and links accounts that belong to the same person.
• Risk signals by name. VPN, proxy, Tor, datacenter IP, anti-detect browser and browser automation, each returned as a named signal rather than one binary flag.
• Risk score. Every visitor, user, device and IP address gets a score from 0 to 100 with the signals that produced it.
• Traffic quality. One score for your traffic, plus a score for every source, channel and campaign.

Who it is for

SaaS, fintech, e-commerce, iGaming, crypto and marketplaces. Five minutes to install, self-serve pricing from a free tier with 5,000 identifications.

How it works

A JavaScript snippet collects more than 100 device and network signals on every visit and cross-checks them against each other, which exposes deep masking with 99.9% identification accuracy. Results arrive through the API and webhooks, and your own code decides whether to allow, challenge or review the visitor. Client SDKs cover JavaScript, React, Next.js and Vue, and server SDKs cover Node.js, Python, Go and PHP.
