Best practices for proxy detection API

An API proxy is a lightweight software tool that reroutes requests to the appropriate service by transforming or adding credentials. It also performs caching and optimizes latency. Popular API testing tools like Postman and JMeter support proxies to avoid unauthorized access and ensure high-speed performance.

Best practices for proxy detection API aren’t only used by fraudsters and cybercriminals to hide their location, but by users of geoblocked websites and for privacy. They are even widely used by web developers and marketers to improve site speed, and by device manufacturers as a way of incentivizing app developer adoption of their SDKs.

Identify and Block Proxy IPs with Real-Time Detection: Prevent Fraudulent Access

The most effective strategy for reducing the risk of unauthorized activity is to combine proxy detection with other methods such as fraud scoring, identity verification, or behavior analysis. Ultimately, the goal is to answer the big question: Is this user truly where they say they are? Or is this a malicious attempt to bypass security and privacy controls, or commit fraud?

In order to detect proxies you should use a solution that combines multiple technologies such as IP reputation, connection type, and device fingerprinting. Additionally, you should include support for detecting private VPN networks used by criminals and TOR exit nodes around the world. A good proxy detection API should also allow you to configure a strictness parameter that can be set to filter out proxies with a low false-positive rate. It should also be able to detect data center connections and server IPs by checking whether the IP falls within an officially published range.
