Proxy server type? Proxy server and VPN?

Although all proxy servers provide users with alternative addresses to use the Internet, there are several different types – each type has its own characteristics. Understanding the details behind the list of agent types will help you make choices based on use cases and specific requirements.

Proxy forwarding

The relay agent is located in front of the client and is used to receive data from user groups in the local network. When sending a request, the proxy server will check the request to determine whether to continue to create a connection.

It is most suitable for the relay agent of the internal network that requires a single entry point. It provides IP address security for people in the network and allows simple management control. However, the relay agent may limit the organization’s ability to meet the needs of each end user.

Transparent proxy

Transparent agents can provide users with the same experience as using computers at home. In this case, it is “transparent”. They may also be “forced” by users, which means they connect without knowing.

Transparent agents are very suitable for companies that want to use agents without letting employees know that they are using agents. It has the advantage of providing a seamless user experience. On the other hand, transparent agents are vulnerable to certain security threats, such as SYN flood denial of service attacks.

Anonymous proxy

Anonymous agents focus on making activities on the Internet untraceable. Its working principle is to represent the users who access the Internet, while hiding their identity and computer information.

Anonymous proxy is most suitable for users who want to be completely anonymous when accessing the Internet. Although anonymous proxies provide some of the best identity protection, they are not without shortcomings. Many people think that using anonymous proxy is a kind of sneaky behavior, so users sometimes face opposition or discrimination.

High anonymous proxy

High anonymity proxy is a further anonymity proxy. It works by deleting your information before the agent tries to connect to the login page.

The server is most suitable for users who need absolute anonymity, such as employees who do not want their activities traced back to the organization. On the other hand, some of them, especially free ones, are bait to lure users to access their personal information or data.

Deform proxy

The fake agent identifies itself as the agent of the website, but hides its identity. It does this by changing its IP address to an incorrect address.

For those who want to hide their position when accessing the Internet, proxy distortion is a good choice. This type of proxy can make you look like you are browsing a web page from a specific country. It can not only hide your identity, but also hide the identity of the proxy. This means that even if you link to the proxy, your identity is secure. However, some websites will automatically block fake agents, which may prevent end users from accessing the websites they need.

Data Center Proxy

The data center agent is not associated with an Internet Service Provider (ISP), but is provided by another company through the data center. The proxy server exists in the physical data center, and user requests are routed through the server.

For those who need fast response time and cheap solutions, data center agents are a good choice.

Therefore, they are a good choice for those who need to quickly collect information about individuals or organizations. Their advantage is to provide users with fast and cheap data collection capabilities.

On the other hand, they do not provide the highest level of anonymity, which may put users’ information or identity at risk.


Residential Proxy

The residential agent provides you with an IP address that belongs to a specific physical device.

Then, all requests are passed through the device.

Residential agents are very suitable for users who need to verify the advertisements appearing on their websites, so you can block cookies, suspicious or unwanted advertisements from competitors or bad people. The residential agent is more reliable than other agent options. However, their use costs are usually higher, so users should carefully analyze whether these benefits are worth additional investment.

Public Proxy

Anyone can access the public agent for free. Its working principle is to let users access their IP addresses and hide their identities when visiting websites.

Public agents are most suitable for users whose cost is the main problem, while safety and speed are not the main problems. Although they are free and easy to access, they are usually slow because they are in trouble with free users. When you use a public agent, the risk of other people accessing your information on the Internet is also high.

Proxy sharing

Multiple users use the shared agent at the same time. They allow you to access the IP address shared by others, and then you can surf the Internet when it seems that you are browsing from the location of your choice.

For those who don’t have much money to spend and don’t necessarily need fast connection, shared proxy is a reliable choice. The main advantage of shared agent is low cost. Because they are shared by others, you may be blamed for the wrong decision of others, which may lead to your being banned from accessing the website.

SSL Proxy

Secure Port Layer Proxy (SSL) provides decryption between client and server. When the data is encrypted in both directions, the agent will hide its existence from the client and server.

These agents are most suitable for organizations that need advanced protection against threats disclosed and prevented by the SSL protocol. Because Google gives priority to servers that use SSL, when used with websites, SSL proxy can help website search engine ranking. On the other hand, the encrypted content on the SSL proxy cannot be cached, so when you visit the website many times, you may encounter slower performance.

Rotating Proxy

The alternate agent assigns different IP addresses to each user connected to it. When users connect, they will get a unique address from the previously connected device.

The rotation agent is very suitable for users who need to perform a large number of continuous and large-scale web scanning operations. They allow you to return to the same website anonymously. However, you must be careful when selecting proxy services. Some of them contain public or shared agents that may expose your data.

Reverse proxy

Unlike the preset relay proxy of the client, the reverse proxy is located in front of the web server and forwards the request from the browser to the web server. It works by blocking requests from users at the edge of the web server. It then sends the request to the original server and receives the response.

Reverse proxy is a powerful option for popular websites that need to balance the load of multiple incoming requests. They can help organizations reduce bandwidth load because they work in a way similar to another web server managing incoming requests. The disadvantage is that if an attacker can invade the HTTP server architecture, the reverse proxy may expose the HTTP server architecture.

This means that if network administrators use reverse proxy, they may have to strengthen or relocate the firewall.

Proxy server and VPN?

On the surface, proxy servers and virtual private networks (VPNs) seem to be interchangeable because they both route requests and responses through external servers. Both also allow you to access websites in countries where you are actually blocked from living. However, VPNs provide better protection against hackers because they encrypt all traffic.

What are the benefits of proxy servers?

The benefits of proxy servers include enhanced security, private browsing, viewing and listening, accessing content in specific locations, and preventing employees from browsing inappropriate or distracting websites.
