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.

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!

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.

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.
