A proxy is a server that hides the real IP address of a request, masking its origin. Proxies are used to bypass website defenses (like CAPTCHAs), circumvent geographical restrictions on websites and online services, and to hide data collection activity from organizations.

While proxies are API to block proxy traffic used by bots and automated tools for malicious purposes, they also have legitimate uses such as load balancing, which distributes network traffic across multiple servers to improve performance. A proxy with an extensive geolocation reach can also help companies avoid violating regulatory requirements or licensing agreements by circumventing geographic restrictions on websites and services by hiding their origin in other countries or regions.

Proxy Verification API: Validate IP Authenticity and Prevent Abuse

A robust API security solution should be able to detect and block suspicious connections in real-time. Fraudlogix’s Proxy & VPN detection API detects the use of proxies, TOR nodes, and anonymizers by analyzing a wide range of factors including user and transaction risk analysis, IP reputation, phone reputation, and physical address validation. Detection signals can be combined into a single API call to take protective actions such as blocking users and redirecting them to a warning page.

The ability to create security actions based on results from these detection rules or dynamic ML models is key to protecting against persistent threats. These security actions can be configured at the environment level to flag or deny traffic based on findings from these detection rules, and they can be augmented by authentication dimensions like developer app, API key, or OAuth token.
