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. Enterprise-level functionality without enterprise pricing.

300+ device and network risk signals are collected together and cross-checked, with 99.9% identification accuracy. Every visitor, user, device and IP address gets a 0-100 risk score with the named signals behind it: VPN, proxy, Tor, Apple Private Relay, datacenter IP, anti-detect browsers, browser automation, bots and AI agents.

High-Risk Events out of the box: multi-accounting, account sharing, impossible travel and account takeover, each with a Medium or High confidence level. No rules to write and no model to train. ShieldLabs helps block fraudulent and abusive traffic.

Traffic quality analytics score every source, channel, referrer and UTM campaign.

Five minutes to integrate with a JavaScript snippet, SDKs for React, Next.js, Vue, WordPress, Shopify and more, plus server SDKs for Node.js, Python, Go and PHP. Self-serve pricing: free plan with 5,000 identifications, paid plans from $99 per month.
