Incredible support and professionalism Incredible support and professionalism. I have a pretty serious bot problem destroying my paid traffic. I tried a solution that wasn't working before finding IPQuality Score. The teams tools are not only better, but the level of professionalism and support I've experienced completely exceeded any expectations I had. The team is generous and capable. Recommend.

The best VPN/proxy detection and device… The best VPN/proxy detection and device fingerprint service in the world by far. Not only are their prices the best, but support is the best I've ever dealt with. Been using for 5 years and here's to another 50!

A blatantly false classification I had my home IP address falsely classified as "high risk", a "VPN" and a "spammer" and as a consequence had my registration for a web site cancelled, and had the administrator of that web site call me a "liar". I have since had an extended email correspondence with the Technical Director of IPQS who has provided no data whatsoever to justify the "VPN" and "spammer" classifications, and for the "high risk" classifications has provided a port scan (which does NOT match an independent port scan) and a browser profile (which matches my own PC but falsely claims I have bad-actor extensions installed), and has somehow extrapolated what are at best (even if the data was correct) mild indications of an untypical home user into a "high risk" user, a "VPN" and a "spammer". In short, their methodology apparently said (based on the flimsiest of evidence) that my usage looked vaguely like that of bad-actors, and thus I must be one too. This is akin to saying that someone is a thief based on the shape of their ears or the bumps on their head. Based entirely on this mis-classification, I then had my registration for a web-site cancelled, and the administrator of that web site explicitly called me "a liar". In short, my internet usage and reputation were both harmed by a false classification by this company of my internet usage as "high risk", a "VPN" and a "spammer". BE WARNED - since their classification is apparently based on extrapolation rather than any proof that will stand up in a court of law, you run the risk of being sued if you use their data to prevent someone using your services in any way shape or form that impugns their reputation. Note: IPQS response to this review is to deny my email domain name exists. That is the level of their technical inabilities.

Ruins legitimate website traffic Their VPN/proxy detection data service is very draconian and leads to many false positives that ultimately degrade the service experience of many clients I have worked with, who have had their users' residential and cellular IP addresses falsely assigned a high fraud risk. I myself have had several instances where I have been blocked by sites using data from IPQS despite using low risk corporate or residential IPs, needless to say causing endless headache. I would not recommend using this company for proxy detection unless you are looking to alienate legitimate website visitors. Additionally, they are not very receptive to requests to unblock IP addresses and seemingly have an arbitrary and secretive process by which they assign fraud scores.

Just in time for the holidays We recently switched over to IPQS just in time for the holiday season to help prevent fraud on our online retail shop. Fraud has really been hurting us the past few months with chargebacks and bad payments. We switched IPQS on and it's been pretty much set and forget. Very happy with the customer support as well.
