The purpose of an anonymous proxy is to conceal a user’s true identity and location when browsing the internet. Users can manually configure their web browsers to use an anonymous proxy, enabling them to bypass censorship and gain access to services that would otherwise be blocked in certain regions or network environments. Anonymous proxies also allow for circumventing geographic restrictions, which can be beneficial for marketers looking to test content or campaigns in new markets.

Proxies leave clues behind, however, and web servers can detect that the traffic is coming from a proxy connection by analyzing HTTP headers. Depending on the type of proxy being used, this may include the “Via” field or the “X-Forwarded-For” header, which can expose the original IP address. This type of leaking data can skew campaign results and lead to an error message, such as “Anonymous Proxy Detected.”

Another way that websites can identify proxy connections is through behavioral detection, which looks for patterns of behavior that are associated with bot activity. This is usually detected by comparing navigational patterns of natural visitors to those of known bots. Websites can then block traffic that exhibits such behaviors to reduce the risk of compromised accounts and fraudulent transactions.

If a website detects that incoming traffic is from an anonymous proxy, it can take action to prevent fraudulent activities, such as blocking the user and requiring them to login with a password or answer a security challenge. The Exinda Appliance can identify this type of traffic, showing it as the “Anonymous Proxy” application on the real-time monitoring screen and other monitoring reports. Blocking this traffic with Optimizer policies can help lower your CPA and prevent invalid proxy traffic from impacting your go-to-market efforts.
