Frequently asked questions

What is ShieldLabs?

Fraud detection and prevention software helps digital products identify risky traffic and abusive account activity. ShieldLabs combines device, browser, operating-system, IP, and network signals to assess visits and surface ready-made detections.

ShieldLabs also scores traffic quality and makes results available in the dashboard, API, and webhooks.

What does ShieldLabs detect?

Fraud and abuse detection covers masked connections, automated traffic, and suspicious account activity. ShieldLabs detects VPNs, proxies, Tor, Apple Private Relay, anti-detect browsers, browser automation, bots, AI agents, and risk signals such as operating-system and timezone mismatches.

ShieldLabs also detects multi-accounting, account sharing, account takeover, and impossible travel as ready-made High-Risk Events.

How does ShieldLabs assess traffic risk?

Traffic risk assessment combines more than 300 signals from the device, browser, operating system, IP address, and network. Each detected risk signal is returned by name, and a Risk Score summarizes the visit on a 0–100 scale.

ShieldLabs reports 99.9% identification accuracy and 99.9% risk signal detection accuracy. The score remains explainable through the signals that contributed to it.

How does ShieldLabs detect multi-accounting?

Multi-accounting is when one person operates multiple accounts on a product. ShieldLabs detects multi-accounting by correlating account activity with visitor, device, and network context, including activity across different email addresses.

The default detection threshold is three accounts per visitor and can be adjusted in the dashboard. The result is a multi-accounting finding, not a report of linked registrations.

Does ShieldLabs detect bots and AI traffic?

Bot detection identifies automated traffic, including browser automation and AI agents, and helps distinguish useful bots from abusive automation.

ShieldLabs returns bot and AI traffic signals alongside device and network context, so a product can assess whether the visit is relevant to its own fraud and abuse workflow.
