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.

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.

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!

Battled fraud for years, IPQS is the best! I’ve been battling fraud for years and have tried nearly every service in the industry. Our site accepts payments and also suffers from account abuse during registration. IPQualityScore is the only service we’ve found that can handle all of our fraud detection, while also verifying users during signup. Very impressive team all around and even more impressive technology. It’s easy to block legitimate users and their tools are very careful with avoiding those issues.

Replaced 3 other services we used Very accurate and customizable scoring. The user platform was easy to use as well. We were previously using 3 very expensive API services for fraud prevention to validate new users and payments and still only getting mediocre results. Now we process all of our data through IPQS and we've been very happy with the results.
