In our blog we often cover various types of proxies based on some specifics related either to origination or use of such proxies. By now, we covered the differences between backconnect (or rotating) and static proxies. We also considered various proxies based on the protocol used by the servers (HTTP(S) or SOCKS). And, of course, we touched upon the major difference in proxies based on their origin: datacenter (DC) proxies or residential IPs

Now it’s time to consider one big aspect of proxy performance: anonymity. You already know that all proxies are meant to hide your original IP while you access a remote target website with some mission. Obviously, you need to stay anonymous in doing so, since some sites are sensitive to proxies and can easily ban such connection requests. 

In this article we will talk about anonymous proxies and the level of anonymity of various proxies. You will learn that not all the proxies are meant to be completely anonymous. Surprise, surprise! And there are reasons for that. We will also discuss the most common use cases for dedicated anonymous proxy service based on the level of anonymity. But we will start with the traditional definition of what the anonymous proxy actually means. So, what is a proxy anonymizer? Let’s find out below. 

So What is an Anonymous Proxy Service?

What does an anonymous proxy mean? As you can see from the name an anonymous proxy (a.k.a. anonymizer, proxy anonymizer, or hidden proxy) connects to the target server on your behalf but as if it was doing it on its own. This ensures the much needed anonymity for your online mission, where your original IP and location remain unknown to the target. 

Both datacenter (DC) proxies or residential IPs can serve as anonymous. The term anonymous denotes the type of mediation between you and the target website.

There are three levels of anonymity when it comes to proxy servers. There are:

Transparent proxies. These proxies do not hide your IP and show the target website that you are connecting through a proxy. Such proxies are also known as forced or intercepting proxies. They are used in public WI-FI networks at hotels or airports for restricting access to some websites. Needless to say that the connection via such proxies is insecure for the lack of encryption. 

Anonymous proxies. An anonymous proxy means that here your IP is not revealed to the target, instead it is replaced by a new one in the header (by HTTP_VIA line). This informs the target site that you are connecting via a proxy. So, some proxy-sensitive sites may restrict access to them, having detected that you are connecting through a proxy.  

Elite proxies (or High Anonymous proxy). This type of anonymous proxy features the top level of anonymity. All the information that can potentially divulge the presence of a proxy in the connection is hidden. You basically appear as another regular user to the target you are connecting to. But how does this proxy do that? The point is that there are 3 headers that a target web server receives from the browser. Such headers contain IP addresses that are used as identifiers. For elite proxies, headers HTTP_VIA and HTTP_X_FORWARDED_FOR do not contain any information. And since these two headers remain blank, the target has no way of knowing that the request is coming through a proxy. The third header REMOTE_ADDR gets modified with an IP given by a proxy. This setup is more secure for hiding your identity online and you get treated as a regular user by the target.

How Do Anonymous Proxies Work?

The principle of work of anonymous proxies should be familiar to you by now. Such proxy accepts your requests and routes it through an intermediate server and later returns the results from the target website. What is important to remember is that your real IP is not revealed during the information transfer. Instead, it is replaced by the IP of the proxy. All this allows your device to appear as a regular user for the target website. 

If you are cautious about the security aspect of your proxies, you need to build a long-term relationship with your proxy provider. Beware providers that are ready to offer you anonymous proxies for free. In this case you are most likely to get shared, overused proxies and leak your personal data to the third party. 

In other words, free anonymous proxies normally act as traps set up by hackers or authorities to steal your data. So, always go to trusted vendors of proxy services for your set of proxies. Later we will cover the main risks of using anonymous proxies and you will understand how “free proxies” can play a bad joke on you. 

Why You Should Use Anonymous Proxies

If your question is how to use an anonymous proxy? We can definitely say that such proxies are great tools for various applications. We are talking about cases that cover both the private and the business sectors. Regular users can apply anonymous proxies for evading censorship online and accessing geo restricted content.

Straight from the dashboard you will be able to copy and paste your proxies into your browser or script (bot or app) of your choice. 

If you are a novice user of proxies, our experienced account managers will advise you on how to set up your proxies for immediate use. 

Anonymous Proxy Usage

What is an Anonymous Proxy? A Clear Explanation

So, what is an anonymous proxy server good for? We have touched upon some use cases of such proxies above, now let’s go deeper into details of how they can be used in personal life and for business. 

You should definitely consider using anonymous proxies if you want to:

  • See less targeted ads online;
  • Solve geo-restriction issues;
  • Get around censorship;
  • Protect your search history.

And when it comes to business related matters, anonymous proxies will help you in:

  • Scraping multiple websites for reputation and price intel with or without bots;
  • Managing multiple social media accounts;
  • SEO monitoring;
  • Testing ad activity of your online campaigns; 
  • Buying rare sneakers online, 
  • Optimizing network caching, 
  • Travel fare aggregation, and more.

With good anonymous proxies you can solve virtually any problem that requires the use of proxies. 

How to Disable Anonymous Proxies in Case You Need

In case you need to disable your anonymous proxy, simply delete its IP from the relevant section of your browser or deactivate it inside a bot by deleting the IP and authentication details. If you still have troubles disabling your proxy or you detect some anomalies in your browsing experience, please contact our account manager to help you solve this issue.  

Can the Usage of Anonymous Proxy Servers Be Risky

Most risks with anonymous proxy services come from “free proxy servers” that can be luring regular users to using such IPs for leaking their data to the third party or government. In other words, if you want to avoid risks using anonymous proxies choose your provider carefully. Make sure that your provider has enough experience in the field and boasts good tech support of the proxies it offers. If you are not sure about the quality of the proxies you are currently using, you can read our article on how to test proxies to make sure that you are getting what you are paying for with publicly available proxy checkers. 

Proxies are legal tools almost everywhere in the world, although, in some countries you should use them with caution. In China, for example, you can be prosecuted for accessing forbidden or censored content.

And again, you can get caught by using free proxies used as traps by the government who wants their citizens to obey the regulations of the Great Chinese Firewall.

Another risk may be coming from hackers who also like to use free proxy services as baits for phishing operations.
