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.

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!

Terrible and dishonest company with… Terrible and dishonest company with crazy prices (500 usd a month is their lowest plan). Script doesn't work, they give you "5000" free credits that are not free. They trick you into creating an account saying it will be "free". Nothing is free with these scammers.

Seems like a nice service, after all There were some initial problems creating an account, but they kindly helped me, and I'm currently reviewing the service's features before deciding on the paid plans. For now it seems like a great deal.

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.
