What Is a VPN? Know Its Concept, Meaning, Types & Full Functions

The acronym VPN stands for Virtual Private Network. This is an encrypted link or connection over the Internet from a particular device like a laptop or desktop to a network to ensure the safe transmission of sensitive information or data. 

Being encrypted, an unauthorized entity cannot decipher the data. In the subsequent paragraphs, we’ll try to know more about it and how it works.

What is a virtual private network

To find an answer to what a Virtual Private Network is, you have to delve into its functional aspects. Under this type of network, you can work remotely, and a third party cannot intrude or interrupt your network traffic.

To protect their sensitive data, sales corporations, corporate companies, and business organizations use VPN, which is a highly sophisticated technology. Under VPN technology, your identity and all other details are hidden. This protects your network from intrusion.

If you want to know what is VPN, then you should look at the following points:

• The server of this technology functions as your proxy on the Internet. 

• Your actual location cannot be found out. 

• Your user behavior remains permanently hidden. 

• Your IP address is hidden.

You also get different other benefits by using VPN technology.

How Does a VPN Work?

VPN works in an ultra-sophisticated way using advanced technology. VPN technology helps your business house in a number of ways through its manifold functions. To provide total safety to your corporate or business network, an encrypted connection through the Internet is used. 

Stealing data or intrusion becomes impossible as your network traffic is encrypted between: 

i. Device 

ii. Network 

iii. Traffic’s travel mode is private, thus maintaining total secrecy.

As for the question of how does a virtual private network (VPN) work, the following pointers can help you understand better: 

• VPN conceals your identity and place of operation. 

• VPN's main working module is to protect your corporate network connection when you are using public networks. 

• VPN works under the regime of real-time encryption of data. 

• Under this technology, any third party, intruder, or even your ISP cannot find out what information (data packets) you are sending (or receiving) when they visit your website (or try to intrude). 

• Effective change of your location is made possible by resorting to VPN technology. By applying VPN location spoofing, you can shift to a server in another country. This can help you change your functional location.

These are the major pointers regarding the working module, functionality, or modus operandi of VPN.

Types of VPN

VPN technology is gaining popularity all across the world due to its effectiveness. VPNs are mainly of three different types. All these types or kinds are popular among users. 

Explained below are these types of VPNs:

i. SSL-VPN Solution: This type of VPN is mostly installed, put into operation, or implemented through a corresponding hardware box. Restriction of access to the network is done with the help of a Username and Password. Implementation of this type of VPN can be made possible through an HTML-5-capable browser and used to call up the organization or a company’s login page. 

ii. Site-to-Site VPN: This can be ideal for your private network. It can effectively hide private internets and secure the network. Only authorized persons with a Username and Password can use it. A large company having several offices in several places can use this type of VPN. Each place with its own LAN can be connected to the WAN. 

iii. Client-to-Server VPN: Under this technology, it is the VPN service provider who plays a very crucial role. This technology is ideal for shortening the tunnel phase of the VPN journey. This system enables the VPN to automatically encrypt the data before making it available to the user. An encryption tunnel is not required under this technology.
