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.

Verify emails and more at IPQualityScore I'm completing a small project for a church and needed to verify 1500 email addresses before we sent our first email blast to the 1500 registered users. The staff provided me with a quick and easy solution, and I was able to verify all email addresses within minutes. I recommend ipqualityscore.com for all of your website Fraud verification and email needs. Their API response time is quick, and the information is accurate and trustworthy. Great job!

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.

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.

This service provider classifies IPs… It was quite an act to reach anyone from IPQs at all, the background is that many scammers try to blackmail IPQs by means of bad ratings that the IPs are listed positively again. The best way to send a false positive report to IPQs is either to write to the co-founder on LinkedIn or to create an account with IPQs and submit a support request. Also prove that you are the legitimate owner IP and do not belong to a proxy/BotNet. e.g.: Registration number of the company in your own country, screenshots of the server and IP address in the admin panel of the hoster "remove important info!", proof that the local IP is registered to your own company It remains at -2 stars due to the major problems that the whole thing caused. Original problem: This service provider classifies IPs with a score of 99 without any proof or evidence. My e-mail to the False Positive Team and the request for evidence for this classification has not yet been responded to. A check of the IP with other service providers has also not revealed any anomalies. An inquiry to our ISP has also provided no evidence that there is any problem that IpQualityScore claims to have.
