The internet contains a lot of valuable information but also many threats. With data breaches becoming more common, more and more companies invest money in robust security systems. However, businesses often only start taking action after they suffer from a cyber attack. And fixing the damage costs much more than installing security features beforehand.


Using a proxy server is a simple and effective solution that helps companies protect their network’s privacy and enhance security. A proxy server has a number of security features, such as content filtering, high anonymity, and data encryption.


But before we jump into features, let’s revisit what a proxy server is, how it works, and how it can help companies improve their security.

What Is a Proxy Server?

A proxy server is an intermediary between internet users and web pages. In other words, it works as a gateway between a user and the internet. A proxy server routes the traffic from the end user to the internet by adding a layer of security by providing a proxy IP address. It also routes the traffic back from the target website to the end user, so they never communicate directly.


A proxy server stands between the internet users and the target websites. It helps users access target websites by routing their requests through a proxy server, which has its own IP address.

How Does a Proxy Server Work?

All internet users have IP addresses assigned to their internet-connected devices. These addresses contain sensitive information about the device. For example, the device’s location, the name of the Internet Service Provider (ISP), and its location.


Whenever an internet user sends a request to a target website, their IP address becomes visible to the site. So does the information about the user. This information can be shielded by routing internet traffic through a proxy server address, ensuring the user’s identity protection.


Every request that the end user sends to a target website goes through a proxy server and accesses the target via the proxy server address. This way, the end user’s IP address is not visible to the target website, which enables the users to surf the web anonymously.


Moreover, besides changing the IP address, a proxy server can also filter content and encrypt data, providing enhanced security.

Is Using a Proxy Secure?

Using a proxy is secure. Companies use proxies to protect their internal servers, and individuals can also use proxies to browse the web anonymously. 


However, to ensure that using a proxy is safe, you need to make sure your proxies come from a reliable source. Free proxies may compromise your security and bring more harm than benefits. So make sure your proxy source is reliable. 


You’ll come across different types of proxies on the market. The main types are datacenter and residential proxies. Their main difference is the source of these IPs. Datacenter proxies come from data centers, while residential proxies come from ISPs and are connected to residential home addresses. Both types of proxies are secure to use and shield your original IP address.

How Does Using a Proxy Result in Improved Security?

Proxy servers improve security by encrypting web requests sent from your computer. This means that even if someone gets their hands on your traffic, they won’t be able to read any valuable information. 


You can also protect yourself from known malware sites. They won’t be able to get any access to you through the proxy server. This can be ensured by deploying a proxy server as a host for your firewall. Firewalls can protect networks from external threats by blocking unwanted access and preventing malware from being installed. Proxy servers will check whether the incoming traffic is legitimate before it accesses your internal network.


Content filtering is another proxy feature that helps enhance security. Users can set up what content should be filtered and stop the network from accessing sites with, for example, certain keywords. This helps protect the network from accessing potentially harmful sites that may contain malware.

What Are the Other Advantages of Proxy Servers?

Enhanced security is one of the main features of proxy servers. But they also have other advantages, such as improved browsing experience and better privacy. Here are the main proxy benefits:

Improved data security

Proxy servers can help protect companies from data breaches. Proxies ensure that there’s no direct traffic between internal and outside servers. A proxy server adds an extra security layer, making it very difficult for attackers to find where sensitive data is stored.

Better browsing experience

Since proxies come from various locations, they can also help access content that may be unavailable at the end user’s original geo-location. Moreover, proxies can help access often-visited sites quicker by caching websites. This helps improve the user’s browsing experience by loading sites much faster.

Improved privacy

Companies use proxies to protect important sensitive data, such as financial documents, private information, etc. Individual users can also take advantage of this proxy feature by anonymously browsing the internet.

Child protection

Parents may use proxies to filter harmful content and make sure it’s unavailable to vulnerable users, such as children. Proxies can also help monitor internet traffic and track how much screen time kids get every day.


A proxy server is a great tool to help companies protect their sensitive information from various threats. A server stands between the end user and the target sites, which means that there’s no direct communication between internal and external servers. This helps avoid potential data leaks and makes it much harder for attackers to access sensitive information.


Along with improved security, a proxy server can also bring other benefits. Among the main advantages are better privacy, faster browsing, content filtering to protect users, and data encryption. 


Regardless of what proxy type you choose, make sure it comes from a reliable source. Only then can it ensure the best security for your internal servers.
