What is a proxy?

Definition:A Proxy (or intermediary server) is a system or software that acts as an intermediary between a user's device and the Internet. When you send a request to access a website, the proxy receives that request, visits the site on your behalf, and returns the data to you.

Simply put, a proxy helps hide your real IP address and provides a “protective layer” while surfing the web.

What are the features of a Proxy server?

Proxy servers provide many important features on wide area networks, typically including:

• Firewall and Filtering

• Share connection with Proxy Server

• Proxy Server and Caching

Popular types of proxies today

Depending on the purpose of use, proxies are divided into several types:

• HTTP Proxy:Specifically designed for web browsing.

• SOCKS Proxy:More flexible, supporting email, torrents, and online games.

• Transparent Proxy:Does not hide IP, commonly used in internal networks to control content access.

• Residential Proxy:Use real IPs from residential devices – suitable for SEO, marketing, and website testing.

• Datacenter Proxy:Provided from data centers – high speed, low cost.

Why use proxies in 2025?

• Security and online anonymity

• Bypassing censorship and geo-restrictions

• Optimized for business and marketing

• Accelerate access speed and save bandwidth

• Access management within the organization

How does a proxy server operate?

Basically, Proxy server is a computer on the Internet with IP address individual that your computer knows. When sending a web request from your computer, it goes to Proxy server first. Here, data will be processed and your request executed, while also collecting responses from web server and return website data so you can see the web page in your browser.

Additionally, it can encrypt data so that no one can read it during transit. Finally proxy server can block access to specific websites based on IP address.

Benefits of using Proxies

After a period of use, I personally found that Proxy servers offer many benefits such as:

• Private: I can use a Proxy server to browse the Internet privately. Some Proxy servers can even alter the IP and identifying details sent with requests. As a result, destination servers cannot identify who made the request. This helps keep my personal information and web browsing habits confidential.

• Control: There are many potential risks on the Internet. When using a Proxy server, my content is filtered and becomes safer.

• Increase speed and save bandwidth: Using a Proxy Server effectively has improved overall network performance. Additionally, it caches popular web pages, helping me maximize bandwidth savings.

• Access blocked content: The Proxy server allows the company to restrict user access to certain content. However, I used an IP-changing Proxy to change my geographic location. As a result, I was able to access the blocked content with ease.

• What is the security level of a Proxy? To prevent third parties from tracking my activities, I configured the server to encrypt web requests. Additionally, I blocked malicious software or websites from being accessed through the Proxy Server. Furthermore, the company I work for can connect the Proxy server with a VPN. Users can access the Internet remotely through the company's Proxy. A VPN is a direct connection to the enterprise network that the business provides to remote users. Businesses can easily control and verify users by using a VPN. From there, users can access resources and use a secure connection to protect corporate data.

What are the disadvantages of a Proxy?

• Access speed is slower than actual capacity. We do not access external networks directly, but rather through a proxy server

• Potential attack risks. Proxy servers may be set up by hackers for malicious purposes. It is not always possible to find an active proxy server to use.

• Sometimes a different proxy is needed for each protocol. Proxy must understand the protocol to determine what is allowed or prohibited. Performing tasks from client to actual server and actual server to proxy client, along with combining, installing, and configuring all those different servers, can be challenging.

• Quite difficult when introducing new services into the system without a proxy for it, it should be placed outside the firewall. Because if placed inside the system, that would be a vulnerability.

How do proxies and VPNs differ?

VPN are not just "pipes" but also encrypted tunnels. Equipped with professional security and protection features, they will help you hide your IP address perfectly. 

When you connect the VPN client on your device to VPN Server then all traffic will be encrypted. They will be secured differently and encrypted at a fairly complex level.

Unlike Proxies, which are only used at the browser level and rely on security vulnerabilities, a VPN applies to the entire computer system with very high security. However, one thing to note is that you will need to pay a fee to access full functionality as well as reliability.
