Proxies are used in 97% of fraud cases. Ensure your customers are real with our reliable proxy detection database to filter risky IP addresses.

Detect proxies, Tor exit nodes, VPN connections and more with leading IP reputation data.

Proxy detection database to filter risky IP addresses to identify proxies is to use a blacklist, essentially a list of known bad connections that are likely to be abused for fraudulent activity. The problem with blacklists is that they’re not always up to date, and they can be abused by criminals themselves to block competition (iGaming was notorious for this).

An alternative is to use a network analysis API that inspects the actual content of the traffic at a more granular level than simple headers. This approach allows for better identification of encrypted traffic patterns that indicate tunneling protocols like proxies. However, these APIs are typically complex to implement and often don’t scale.

Another issue is that even with a good network analysis API, it can be challenging to get accurate results. For example, it is well understood that some IP ranges are more likely to be proxies than others (such as the ones used by companies like AWS and Digitalocean) and this can lead to false positives.

The best way to avoid these false positives is to use an IP reputation API that can distinguish between a true proxy and one that has been flagged as non-proxy for other reasons. This will allow you to remove the proxy from your customer’s connection without impacting genuine users.
