Proxies – A Brilliant Online Privacy Solution You Might Not Know

Reading Time: 6 Minutes

The Internet began as a partnership between academics and the military, with the primary goal of allowing the sharing of information at a quicker rate than ever before. Initially, privacy and anonymity were not its primary priority. Over time, the Internet grew into the huge network that we know today, and when companies entered the picture, the issue of privacy became increasingly important. Today, protecting privacy is a fundamental component of the Internet’s operation, and it is still a source of heated dispute.

Privacy is like securing your house—you must take matters into your own hands. No one will do it with a click of a button, and those who claim to do it likely have something else in mind. Proxy servers are tools that can help everyone access the Internet with the level of privacy they want. 

What Are Proxies?

Proxy servers serve as a firewall and web filter, providing shared network connections and caching data to speed up common requests. They also offer a high level of privacy by acting as an intermediary for users, passing through all Web requests and responses. Proxy servers constantly change their IP addresses to avoid detection, and data combines multiple lists of known proxy IP addresses and proprietary lists to detect larger proxies. They serve as a “middleman” between a user and the web, hiding the user’s IP address from a web server but not securing the data sent and received. VPNs take this process further by hiding the user’s IP address and location so they cannot be identified.

A proxy server reads and interprets a device’s request, forwards it to the correct internet server, reads the proxy’s IP address, and sends the requested data to that IP address. The proxy then receives the data, extracts it, and checks it for malware.

Network Requests, Ip Addresses, And Identification

Each time you connect to the Internet, whether for entertainment, work, or any other reason, your device sends a data packet with a request. This request instructs the target server what information is needed, but most importantly, it also informs it about who is requesting it.

Just as physical mail cannot travel without an address with a postcode, a network request between devices cannot be sent without an IP address. IP is an acronym for Internet Protocol – a series of rules instructing devices on communicating with one another. There are some variations in such protocols, but they all require devices to have a standard IP address.

It’s a string of characters like this: 192.168.0.1 (IPV4) or 2001:0000:130F:0000:0000:09C0:876A:130B (IPV6). Internet service providers (ISPs) assign them to each device connecting to the Internet. Because your local ISP assigns them, everyone can tell your approximate locations from these characters alone.

Proxies – Intermediary Devices

To hide your identity online is to hide your IP address. Unfortunately, no device can connect to the internet without an IP address. It’s one of the most basic rules of internet communication. Even if you’d instruct a device to send requests without the IP address, they would be denied, and connection would not happen.  

The only viable alternative is to use an intermediary device instructed to perform actions on your behalf. In such a case, the target server would not know your original IP address, be unable to track your activity, or determine your location. Such intermediary devices are called proxy servers.

The name is misleading since servers are used only in a few proxy types. Nowadays, mobile phones can even act as proxy devices. However, it only changes the functioning of a proxy service a little. 

The proxy device connects to the internet normally and is assigned its IP. Another device then connects to it, allowing it to forward all requests. So, if you use an Indian IP proxy, everyone on the internet will treat you like a visitor from Mumbai or elsewhere in India.

Benefits Of Proxies

Avoiding IP bans. If your original IP address is blocked or restricted in any other way, a proxy server can allow you to bypass it easily. You simply change your IP in another location by using a proxy device, such as a private proxy. The loss is minimal if the proxy IP is banned, as you can use another one.

Location Targeting 

Proxies are technologies that conceal a user’s IP address and mimic a location, allowing businesses to target certain audiences in various countries precisely. They are helpful for targeted advertising since they enable advertisers to examine geographical location, internet behavior, and other data. Rotating proxies allows users to access and evaluate location-based information, which improves ad targeting and consumer engagement. Moreover, proxies benefit geotargeting campaigns by providing anonymity and privacy through disguised IP addresses. Also, they allow advertisers to avoid regional constraints and gain access to information, advertising platforms, and social media channels particular to their area. Overall, proxies are an effective tool for firms looking to optimize their geotargeting strategies.

Anonymity 

Proxies, also known as anonymizers, function as a conduit between the internet and a user, concealing their IP address and delivering identification data to the connection request header rather than the target site. This makes it harder for websites to monitor users’ online behavior and determine their location. Proxies may be used to browse the internet anonymously, overcome content restrictions, gain access to restricted sites, do SEO research, monitor marketing, and scrape web pages. However, utilizing a public proxy server is less secure than accessing a web server via a browser. Proxies are classified into three types according to their level of anonymity: transparent, anonymous, and elite. They serve as a middleman and privacy shield, safeguarding personal information by concealing identifying information such as IP addresses.

Enhanced Security 

When a device’s IP address is masked behind a proxy server, malicious actors have a harder time attacking it. The proxy server acts as a go-between for the device and the outside world, checking incoming requests and blocking suspicious ones. The originating device may continue to operate normally without impacting performance while the proxy server identifies and deflects potential threats. This is why proxies are commonly used to secure web servers and filter incoming emails: they provide an extra layer of security to help protect sensitive information.

Protection Against Cyber Threats

A proxy server is a firewall between a client device and the internet, intercepting and filtering incoming traffic to defend against cyber risks such as hacking, phishing, and malware. It can stop dangerous content, restrict unauthorized access, and filter spam and unsuitable information. FTP proxies turn on or off file transfers based on source/destination IP addresses and user authentication. VPNs provide privacy and security by routing and encrypting traffic via a secure server. Proxies act as intermediaries between a client device and the internet, masking the client’s IP address and encrypting data, making it more difficult for hackers to locate specific devices and protect critical information from surveillance and cyber thieves.

Aren’t VPNs The Same Thing?

You might have already noticed that other privacy tools can accomplish these feats. Virtual Private Networks (VPNs) are the most common example, as they are aggressively marketed for common consumers. However, the brilliance of proxies lies in one benefit I still need to mention – compatibility.

The convenience of VPNs is their biggest weakness. Yes, it’s easy to press a button and change your location while encrypting the data you transfer. However, a VPN provider will never allow you to have real access to the IP addresses you use. You can only access the VPN through their software.

Yes, with much know-how, you can set up a VPN for your home router or with some selected software, but proxy servers are much simpler. When you purchase a proxy server, you get its credentials—IP address, port number, and (sometimes) a password. That’s it.

It looks inconvenient for those who expect a user-friendly experience. But if you know what you are doing, this is the main benefit of proxy servers. You can insert proxy credentials in almost any software – from browsers and operating systems to specialized tools automaton.

Such flexibility results in applying proxies in various business and individual use cases. Below are some prominent examples. 

  • Web scraping allows users to collect data automatically for data mining, market research, lead generation, price monitoring, e-commerce, SEO, and many other use cases.
  • Online automation tools create an opportunity to manage multiple social accounts and perform web tasks more efficiently.
  • Anti-detect browsers, with the help of proxies, help you spoof your browser fingerprint.

Conclusion

Proxy servers are an extremely effective and unique solution that allows users to protect their privacy and security while being flexible in their online activity. Individuals who take the time to learn how to integrate proxies into their workflows can get various benefits that will revolutionize how they function online. 

Moreover, proxies have become popular for enterprises of all sizes, offering more security and anonymity and enhanced speed and access to geographically restricted content. Therefore, as the advantages of proxies become more widely recognized, it is only a matter of time before they become a consumer market staple.
