Real-time scoring
Detect suspicious users & payments with real time fraud scoring that analyzes how likely a user or visitor is to engage in fraudulent behavior. Our fraud prevention tools validate a user’s data and identify the likelihood of them committing credit card fraud, click fraud, IP address fraud, and other types of online abuse with more accuracy than other providers. This information is then used to automatically flag, reject, or block users with the highest risk levels without interrupting trusted & legitimate customers.
Reduce chargebacks & lost revenue with accurate user scoring for ecommerce & retail, lead generation & iGaming, and other industries. IPQS provides a robust set of user and transaction scoring rules including proxy & VPN detection, device fingerprinting, email validation, phone verification, and more. Our system also performs advanced reputation scoring and validation with hundreds of syntax & DNS checks.
SEON also enables you to adjust all of the fraud score settings and thresholds yourself to match your business’ specific risk appetite. This allows you to avoid the one size fits all approach of other anti-fraud solutions. SEON’s machine learning rule suggestions are fully transparent and human-readable, so you always know exactly what impact a rule would have on your overall risk scores. For example, you could make a rule that adds +10 points to anyone using a proxy or VPN connection while simultaneously lowering the thresholds for data centers and telecommunication providers.
Proxy Detection
Detect Proxies, Tor nodes, VPN connections & other shared connection types preferred by fraudsters & cybercriminals online. Prevent fraudulent registrations, orders & logins with the industry’s most advanced proxy detection based on honeypots & traps, blacklists, forensic data and client feedback.
The IPQS risk API instantly scores any click, payment or user based on the following key variables:
Overall fraud score indicating the likelihood of bad behavior. Higher scores indicate a greater chance of fraudulent activity.
Fraud risk level based on reputation scoring across the entire threat network that spans every continent. Higher scores indicate a greater chance of abusive behavior like credit card fraud, spamming, bots & other automated fraudulent activities.
Is this an open proxy, SOCKS server, TOR node or other compromised network?
The IPQS reputation API provides real-time lookups for over 30 key data points about the device, user, and their location. This information includes geo location data, ISP, Connection type, Device details, Recent reputation history, and much more. With this information, IPQS can accurately determine if the user is connecting via a proxy or VPN in real-time. This helps prevent fraudsters from creating duplicate accounts, posting spammy comments & messages, scraping sensitive content, evading country specific filters or other high risk behavior on your site. The results are instantly displayed as a simple risk score so users with a high risk can be blocked, flagged for review, or redirected away from critical parts of your site.

This service is ideal for affiliate agencies & advertisers that want to avoid fake & duplicate accounts, merchants that want to reduce chargebacks, and forums that want to protect their user base from spammers.
Our email validation API performs extensive syntax & DNS checks to verify an email address is valid. This is crucial for any website, software, or application that needs to communicate with an email system. It also detects high risk users such as disposable email services, SMTP blacklists, and frequent complainers that will negatively affect your sender score.

This includes proxies, Tor nodes, VPNs, residential proxies, botnets, malware & spyware, and other bad shared connections.
