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.

Been using IPQualityScore.com for 5… Been using IPQualityScore.com for 5 years on our network of sites and the service has been absolutely FANTASTIC! Couldn't recommend a better proxy checking service. They are the best in the world by FAR!

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!

IPQS is great, accurate, and affordable IPQS is great and easy to use. The service has a 5,000 free credits per month plan and its super accurate compared to other similar providers. Along with being much more affordable, the risk scoring data is accurate all over the world. It helps verify accounts and investigate suspicious behavior that we otherwise wouldn't detect.

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.
