Professionals I had to deal with them as my personal IPv4 address kept on being blacklisted by their services. It was quite difficult to get in touch with their support, hence only 4 stars. As soon as I got in touch with them they were willing to assist and help in solving the issue. We are now actively exchanging emails on how to solve the issue and to understand what is causing this blacklisting as they want to improve the quality of their data.

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.

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!

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.

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.
