The best fraud detection service I've been using IPQS for nearly 2 years now and I'm confident to say that it's the best fraud protection/invalid traffic filter out there. I run a few websites and I monetize their content using display banners, mainly from Google Ad demand. Anybody that works as a publisher for Google Adsense/Google AdExchange knows how sensitive Google is when it comes to invalid traffic, and it's ultimately our job to make sure our traffic is clean and legitimate. That's why I use IPQUALITYSCORE services to filter out bots, proxies, and VPNs from my websites. Just include a simple JS tag or PHP file and you are all set. I've tested similar services, but IPQS was the one with the most accurate detection and fewer false positives. I really recommend them.

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.

IPQS makes it really easy for our team… IPQS makes it really easy for our team to validate payments and ship orders without worrying about the risk from chargebacks. The support team is also great, and I always get a fast response back. Pricing is very competitive and I have no complaints about the service or accuracy.

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!

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.
