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.

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.

IPQS makes it really easy for our team… IPQS makes it really easy for our team to validate payments and ship orders without worrying about the risk from chargebacks. The support team is also great, and I always get a fast response back. Pricing is very competitive and I have no complaints about the service or accuracy.

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.

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!
