What is VPN and proxy detection?
It helps you see when a visitor's IP is likely using a VPN, proxy, Tor, hosting infrastructure, bots, or privacy relay services so you can adjust trust and review rules.
See anonymized and risky IP traffic clearly
VPN and proxy detection helps you understand when a session is likely hiding its true network path. Greip surfaces that context alongside your IP intelligence so risk teams can act with more confidence.
Use it during signup, login, high-value checkout, and payout reviews when location and network trust matter.

Problem
Fraud and abuse teams often see the same promo claimed from many regions, accounts created in bursts, or payments that do not line up with where the customer claims to be. VPNs and proxies make those patterns harder to see if you rely on country alone.
Blocking every anonymized connection sounds safe but frustrates legitimate remote workers, travelers, and privacy-conscious buyers. You need nuance, not a single on/off switch.
Solution
Greip VPN and proxy detection highlights when an IP is associated with a VPN or proxy, the Tor network, hosting or cloud providers, automated bot traffic, or privacy relay services when applicable. Risk and product teams use those signals to require extra verification, cap incentives, route suspicious sessions to review, or pair network context with IP location intelligence and payment checks.
Using a VPN is not proof of fraud. Treat network signals as one input alongside email, phone, device, velocity, and payment behavior. Many merchants step up verification or limit high-risk actions instead of declining every VPN session outright.
Evaluate a single address with the free proxy and VPN checker. Technical teams can connect through Greip using the VPN and proxy detection documentation and related IP security guides.

Frequently Asked Questions
Where should we use these signals?
Signup and trial flows, login and account changes, high-value checkout, and payout reviews are common places teams apply network context alongside other fraud checks.
Should we block every VPN user?
Usually no. VPNs are widely used for privacy and remote work. Many businesses require extra verification or limit certain actions instead of blanket declines.
Can we test detection before integrating?
Yes. Use Greip's free proxy and VPN checker to review a single IP. Your engineering team can find connection details in the Greip documentation.
