The Most Intelligent
Proxy Detection API Service

What Makes Our Proxy Detection Service Different?

IPQS provides the most accurate proxy detection service in the industry. Through the use of proprietary honeypots & traps, blacklists, forensic analysis, and client feedback loops, we are able to detect compromised connections and risky users to a significantly higher degree than any other anti-fraud service. Score users beyond just the IP address for the best accuracy by passing additional data points such as device info, transaction info, and personal information (email address, physical address, phone number). IPQS also allows for the most flexible and customizable scoring settings to tailor the service to your audience. Never worry about false-positives again, IPQS detection will adapt perfectly to any site or app.

We welcome you to test our proxy detection solution as every user is awarded 5,000 free lookups per month and additional lookup queries are the most affordable in the industry. Easily connect to our tools like the VPN Detection API to detect any proxy IP address. Our goal is to help your website prevent fraud, increase ROI, & save you money at the same time! Detect malicious bot IPs and high risk behavior with ease. Coding examples and plugins make it easy to integrate our service in less than 5 minutes.

Leading IP Reputation Service

Take advantage of the internet's best IP reputation data to make intelligent decisions about your users, clicks, purchases, and similar user behavior. Receive accurate results worldwide in any region of the world. With full support for detecting bot traffic and malicious behavior, you can feel confident that IP addresses processed by IPQS proxy detection are reliable and accurate. Smart scoring avoids false-positives that can occur for IP ranges shared by multiple users and frequently recycled.

Fraud Scoring and Proactive Fraud Prevention

The fraud prevention industry has different approaches for dealing with malicious IPs. IPQS believes the best way to manage fraud is to completely prevent it from happening in the first place as this saves time and has a higher success rate in reducing overall fraud. Rather than review post-analysis reports or receive notifications after fraud has been committed, IPQualityScore can prevent fraud and high risk behavior in real-time. This approach allows you to block proxy and VPN connections and adjust scoring settings in real-time. Easy integration can offer complete ecommerce fraud protection or any other type of abuse by bad users.

All of our anti-fraud tools also return a real-time "fraud score" so that users with a fraud score in a high risk threshold are detected and blocked, flagged for review, or redirected away from critical parts of a site like a registration or payment page, comments section, click funnel, etc. This approach successfully results in fewer problems with managing users, clients, & advertisers. Let IPQS automate your quality control and greatly reduce time spent on cleaning up abuse such as manually detecting duplicate users, clearing user generated SPAM, and blocking high risk users.

IP Reputation Scores

IPQS Proxy Detection API can accept additional information to enhance the "fraud score" accuracy and improve detection for malicious IP addresses. We recommend passing the user agent (browser), user language, and additional details found on the user dashboard into each API request. These data points improve our ability to detect anonymous proxies, VPN providers, TOR exit node connections, and other types of proxy servers.

Full transaction info including billing, shipping, and credit card data can optionally be scored as well. This gives IPQS greater insight than just examining an IP address so we can give you the most accurate prediction of fraudulent behavior for each lookup. IPQS fraud scoring combined with the status of the lookup as a proxy connection, VPN connection, or Tor connection is a proven solution to preventing fraud and abuse.

Feed IP reputation data directly into your preferred security platform featuring our API and on-premise threat intelligence feeds.

Better Proxy & VPN Detection

With best-in-class features like our VPN detection API, stay on top of the latest threats by also detecting VPNs and TOR exit nodes in every corner of the world. Fresh data ensures you can detect VPNs even with newly assigned IP addresses. Identify private VPN networks used exclusively by abusive fraud rings and view VPN providers for any IP virtual private network (VPN) connection.

Data centers, hosting providers, and server IPs are also detected in the "connection type" parameter. Easily prevent VPNs from accessing your website or enable additional verification for risky IPs.
