What is VPN and proxy detection?

VPN detection and proxy detection identify masked connection types around a visit, including browser-level masking and other anonymized connectivity.

How does ShieldLabs VPN and proxy detection help prevent fraud?

ShieldLabs detects network masking, including residential and mobile proxy activity, with identification risk and account abuse detections. Help protect account access, incentives and traffic quality.

Does anonymous proxy detection cover residential and mobile exits?

ShieldLabs detects proxy masking, including browser-level VPN or proxy use, Tor and privacy relays. Residential or mobile exit context may be available. A separate residential proxy detection or mobile proxy detection flag is not guaranteed for every visit.

Does a masked connection always mean fraud?

No. A VPN or proxy detection identifies network masking. ShieldLabs also provides a ready-made trusted, suspicious or dangerous risk assessment for the identification.

Can ShieldLabs reveal an additional IP address?

An additional IP address is included when it is available. Returned network results show the addresses and masking detections available for that visit.

How do I use the results?

Receive available network and risk data through API responses and webhooks, and integrate selected data points with your signup, sign-in and access workflows.

Does VPN and proxy detection have uses beyond regional pricing?

Yes. Use it around account access, signup incentives, checkout, content access and acquisition traffic. Ready-made account abuse and risk detections help protect these workflows behind masked connections.
