You have likely heard about proxies at least once in your life. But what are they and why are they so crucial for cybersecurity in the modern day and age? Keep on reading to learn more about proxy servers and the crucial role they play in cybersecurity.
What Are Proxy Servers?
Proxy servers work at a network’s perimeter behind an exterior firewall, relaying data between the internet and network users. Their primary goal is to hide your IP from the Internet, protecting your privacy and security.
Proxy servers also act as the caching mechanism to reduce network traffic, speed up transactions, and improve performance. They achieve this by locally holding previously requested content.
But that is not all. You can also use proxy servers for controlling both outbound and inbound traffic. Moreover, logging traffic proves to be useful for networks that require to meet certain de-facto industrial standards or security audit requirements.
Finally, you can use proxy servers for bypassing a firewall. For example, a user in a LAN or local area network may want to check a certain blocked IP address, such as Instagram. To do this, they will need to use a proxy server so they can finally access a blocked website.
What Are Residential Rotating Proxies?
A residential rotating proxy is the kind of proxy server that acts as the intermediary for all traffic between a person’s devices and the websites they connect to with constantly changing IP addresses. This means you’ll get a new IP address every 5 or 10 minutes, or every connection request. The specific configuration usually depends on a proxy provider
Normally, a proxy server provider routes your traffic through the data center. But a residential proxy routes your traffic through the phones or computers connected to home ISPs. This makes a residential proxy even more anonymous as it better hides the fact that you are using a proxy, which minimizes the chance that the connection will be blocked.

Proxy Servers and Cybersecurity: A Dynamic Duo for Digital Defense
As previously mentioned, the fundamental purpose of a proxy server is hiding the user’s IP or even the IP of the internal servers depending on a user’s setup. This is crucial for network cyber security since most cyberattacks attempt to gain access to certain target machines. Additionally, cyber attackers may try to scalp credentials from the victim to escalate the fake user’s permissions.
The attackers use IP addresses for mapping out an internal infrastructure so they can learn what to exploit in the network. Blocking IP addresses will make it hard for cybercriminals to target certain users or platforms. Moreover, you can also try using geo-filtering, which can stop attackers from gaining access to websites from certain regions of the world.
You can also use a proxy server to create a DMZ or demilitarized zone, enabling all traffic to enter the no-trust segmented network zone. Once you do this, users will require explicit rather than implicit trust to do anything while being in the DMZ zone.
