Overview
ShieldLabs is fraud detection and prevention with traffic quality scoring. It detects users running multiple accounts, account sharing and account takeovers under any masking, so you prevent losses from free-trial, bonus, promo and API abuse.
Email checks, IP limits and cookies do not stop one person with a VPN, a residential proxy and an anti-detect browser. ShieldLabs looks underneath: it identifies the visitor, user, device and IP address behind each visit and checks whether they are masked.
How it works
One 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.
For each visit you get:
- A persistent visitor ID that survives cleared cookies, incognito and IP changes.
- A risk score from 0 to 100 in three bands: Trusted, Suspicious, Dangerous.
- Named risk signals: VPN, proxy, Tor, datacenter IP, anti-detect browser, automation.
- Traffic quality by source, channel and campaign.
The score arrives through the API and webhooks, and your code decides what to allow, review or block.
Key features
- Identification: recognize the same person across sessions, accounts and devices.
- Risk signals: VPNs, proxies, Tor, Apple Private Relay, anti-detect browsers, bots and AI agent traffic, each returned by name.
