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.

The best VPN/proxy detection and device… The best VPN/proxy detection and device fingerprint service in the world by far. Not only are their prices the best, but support is the best I've ever dealt with. Been using for 5 years and here's to another 50!

Professionals I had to deal with them as my personal IPv4 address kept on being blacklisted by their services. It was quite difficult to get in touch with their support, hence only 4 stars. As soon as I got in touch with them they were willing to assist and help in solving the issue. We are now actively exchanging emails on how to solve the issue and to understand what is causing this blacklisting as they want to improve the quality of their data.

Incredible support and professionalism Incredible support and professionalism. I have a pretty serious bot problem destroying my paid traffic. I tried a solution that wasn't working before finding IPQuality Score. The teams tools are not only better, but the level of professionalism and support I've experienced completely exceeded any expectations I had. The team is generous and capable. Recommend.

Predatory/Scam I don't know what kind of predatory/scam IPQualityScore.com is or why they have targeted my IP address but I have repeatedly tried to contact them and have heard nothing back.I will not pay them for targeting me.DO NOT TRUST. To update the situation,after reading this review I was contacted by IPQualityScore.com and they quickly corrected erroneously blacklisting my IP address. Advice for anyone falsely being blacklisted by a company like this,I had to write this negative review for them to respond to me and fix their error.There seems to be a lack of laws and regulations regarding private companies falsely blacklisting individuals IP addresses.If you are experiencing this and the company ignores you or refuses to work with you on fixing it you can file a complaint with the FTC or the FCC depending on your situation.
