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.

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!

IPQS Fraud Intelligence is best solutions IPQS offers many features that help my business protect itself from fraud activites on the internet. I use IPQS for email validation so that it can quickly browse through my email addresses for legitimacy and recognize suspicious email addresses, which are frequently utilized for fraudulent purposes. Also, it can recognize when a client is interfacing with a site through an intermediary, which can be an indication of dubious action. Their API interface reaction time is very fast, and the data is accurate and reliable. I've been using IPQS for few months now and I can say that it's one of the best fraud detection solutions in the market

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.

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.
