A proxy server is an intermediary server that separates end users from the websites they browse. This type of server is software that works as a proxy or a system that is able to not show the user’s real identity. This system can also provide access to the internet network using the IP address of the proxy server. Proxy servers have various levels of security, privacy, and functionality in use cases according to company needs or policies. By using a proxy server, internet security is more guaranteed and can be used safely.

After knowing what a proxy server is, there are advantages that users get while using this server. First, by using a proxy server, users can control and monitor internet usage. For those of you who have a business or company, you can apply a proxy server to monitor how employees use the internet while working. Second, the use of a good proxy server can save bandwidth and increase speed so that network performance is better.

Then, the use of proxy servers by individuals and companies has benefits in the form of privacy. This allows users to browse or surf the internet more privately. Some proxy servers will change the IP address and other identifying information that contains the web request. This means that the destination server does not know the user who made the initial request. In addition to the benefits in the form of privacy, users can configure their proxy servers to encrypt web requests so that data translated into code cannot be read by any party as a form of increased security.

For remote users, companies can also install proxy servers with VPN (Virtual Private Network) which allows users to always access the internet. By using VPN, companies can provide a secure connection for users to protect company data while being able to control users to have access to the resources they need such as email and internal data. Not only the advantages of using a proxy server, but this type of server also has several main functions that you need to pay attention to.

4 Proxy Server Functions

1. Masking

Masking is a function of a proxy server to hide the user’s IP address and replace it with a different IP address. This function is usually used to maintain user privacy and complicate the process of identifying locations and connecting certain web activities with users.

2. Connection Sharing

In this function, the proxy server functions as a device used to connect a network on one computer device with another device that is the boundary between the local network and the external network. A number of connections from local and external networks will be connected so that the connections owned by the device will be used together. In short, all users can access the internet through one path so that computers can share data access through the same server.

3. Filtering

Filtering is a proxy server function as an information sorter. This function is used to prevent interference from external networks so that it can protect the local network. Through this function, the proxy server can minimize virus attacks.

4. Caching

Finally, this function has a mechanism for temporarily storing data requested by servers on the internet. This one function will make it easier for users who want to access data again because the proxy server will provide data that has been stored on the server.

Judging from the previous explanation, of course the proxy server has an important role in computer networks, especially in terms of security. There are many benefits and functions on the proxy server that can help users in carrying out daily internet activities. To maximize its use, you can use Server Monitoring from Netmonk Prime and do a direct trial for 14 days to monitor daily proxy server usage.
