Can anti-fraud systems see that I am using a proxy


как работает система антифрод

Modern anti-fraud algorithms can detect the use of proxies. Proxy services help users hide connections to bypass geographical restrictions or protect personal information. But they are also used by scammers to hack sites or steal information.

That’s why defenses use proxy detection to understand how users connect to websites, figuring out malicious agents who are masking their data.

Why anti-fraud systems pay attention to proxy servers

The security of a resource depends on how an anti-fraud system works. There are several reasons why antifraud systems pay attention to proxies, all of them are aimed at content protection, so they are constantly being improved to reduce risks:

  • Identity hiding. Proxy servers hide the IP address, which makes it difficult to track users. This is a problem for antifraud, as it relies on this data to detect fraudulent activity.
  • Restriction circumvention. Proxies are used to bypass geographic or access restrictions set by websites. Which helps fraudsters access services or content they shouldn’t be able to access.
  • Fraud. VPN servers are used by fraudsters to steal personal information, hack into accounts, or conduct financial transactions.

Therefore, antifraud makes sure to pay attention to proxies to better protect users and your own resources from fraudulent activities.

How an anti-fraud system works

Antifrod systems see the use of a proxy server. This software system or engine analyzes transactions and user behavior to prevent, detect, and respond to criminal activities, using a variety of methods and technologies to detect and prevent fraud, including the following:


Antifraud monitors volumes of data collected from various sources to detect anomalies and unusual patterns of behavior. For example, analyzing a transaction by parameters: location, amount, time, to identify suspicious activity.


The software tracks and analyzes user behavior to determine if it is anomalous or similar to known fraudulent schemes. For example, session times, frequency of login sources, and user activity.


Artificial intelligence algorithms are used to detect and predict suspicious activity. For example, based on historical data, the program can build ways to create new fraudulent schemes.


Continuous monitoring allows you to respond quickly to suspicious activity by blocking access or rejecting transactions until further verification is performed.


The principle of antifraud depends on the specific purpose and application. Thus, both businesses and end users are protected from cyber threats and loss of revenue.

How antifraud systems see the use of a proxy server

Detection occurs by analyzing the IP address. The program compares the IP to known lists of good and bad addresses, as well as to proxies or VPNs. So, as anti-fraud systems see the use of proxies by analyzing the server from which the request comes. The program determines reliability by answering the following questions:

  • Is the user really where they say they are?
  • Are they trying to connect to a service they shouldn’t be accessing?
  • Are they using suspicious technology designed to alter their IP address?
  • Are they likely to be fraudsters or cybercriminals?

The answer to the last question can only be answered by combining proxy detection with other methods such as risk assessment, identity verification or behavioral analysis. Here’s how antifraud detects proxy use. In sum, it automatically avoids many online crimes, without the need for human resources.

How to avoid false positives of antifraud systems

Of course, automatic anti-fraud is convenient, but mistakes happen and each of them must be dealt with separately. Therefore, in order not to react to such triggers, it is worth using the following tips:

  • Establish an operational baseline. This will help you understand which transactions are normal for your organization and which may be suspicious.
  • Divide the risk into different categories. Once there is a clear idea that the team is able to process data quickly, there will be a chance to develop strategies to manage resources for the best defense against fraud.
  • Review and update policies. They have a responsibility to remain relevant and effective.
  • Automate fraud detection processes. Automation is able to scan many transactions at high speed, paying attention to small discrepancies.
  • Review fraud prevention procedures. Look at all risk rules, consider whether they are too expansive or strict.
  • Sandbox testing of risk rules. A reliable way to determine false positive rates.

If all aspects are followed, antifraud can handle the influx of visitors to the site without requiring human resources for protection.

Tips for ensuring anonymity and security when using proxies

Anonymity and security of the user remains a necessary part of visiting the web. This can be ensured in affordable and legal ways to protect not only the account, but also Internet payments, messengers and e-mail messages from hacking. Whether to use each suggested method separately or jointly is up to everyone to decide for themselves, but 2-3 technologies are still necessary to resist fraudsters:

  • Use mobile proxies;
  • Use paid proxy resources;
  • Choose an appropriate level of anonymity;
  • Use a vpn connection;
  • Choose a browser that respects privacy;
  • Use anonymous search engines;
  • Use secure email applications;
  • Protect your social media settings.

Don’t neglect protection, even if you don’t frequent social media or use online stores for shopping. Even getting a chance to save yourself from having your email hacked with sending unsuitable content will already feel good.
