proxy detection solution shows that proxy and VPN usage is behind 97% of fraud cases. This makes it crucial to implement a robust proxy detection solution in your website.
Proxies are used for a range of malicious purposes, from bypassing geographic content restrictions to spamming. The ability to identify proxy users is critical to preventing the most common types of fraudulent online behavior, including account creation, logins, credit card fraud, click fraud, and more.
The best proxy detection tools analyze data points such as OS, browser type and version, and network connection to detect the presence of a proxy. More advanced tools also examine the contents of packet headers to reveal corroborating information, such as user-agent strings or connections that appear to use tunneling protocols (e.g. X-Forwarded-For or Forwarded headers).
Many of the most effective proxy detection tools are provided as part of a fraud scoring service, where they can be used to flag suspicious transactions or users for further inspection. This allows businesses to prevent proxy activity without removing legitimate traffic from the site or blocking users who don’t have malicious intent.
How Proxy Detection Solutions Work Behind the Scenes
Fraudsters who register or login with proxies, Tor nodes, or VPNs are likely to create duplicate or fake accounts, commit credit card fraud or chargebacks, engage in advertising click fraud, scrape sensitive content, or other high risk behaviors. IPQS provides best-in-class proxy detection by using data from public reputation databases to compare the IP against a database of known proxy server IPs, Tor exit nodes, and VPN services.
