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!

Good so far! Been using for months now, great service and support very responsive. Just a shame their non-free plans are such a big jump up from the free ones.

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.

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.

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.
