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!

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.

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.

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.

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.
