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.

GREAT TEAM, VERY ACCURATE DATA! Our company tested IPQS against 10+ service providers to determine the best IP address data and then again against 15+ service providers for email validation. IPQualityScore outperformed by a significant margin across both services (email + IP). We were also impressed with the quick response times from their support team and our account rep. Their data is a much higher caliber than what's typically found in the industry and you can see that the team works hard to maintain their edge against fraudsters.

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.

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.

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.
