What is a Virtual Private Network (VPN)?

A VPN aka Virtual Private Network enables the connection of a private network across a public network. Virtual Private Network programming ensures a safe and encrypted connection across the public internet which is mostly less secure. A Virtual Private Network implements tunneling protocols for the encryption and decryption of the data at the sending end and the receiving end respectively. In short, a VPN network safeguards your online data from snoopers, hackers, cyber thieves along with maintaining unrestricted access to spam and blocked websites and services. VPN technology was originally developed to enable the access of corporate applications and resources to remote employees and branch offices.

How does a VPN Network Work?

When your computer or any similar device is connected to the VPN, the device acts as if it is on the same local network as the VPN. A VPN routes your device’s (PC, Tablet, Laptop, etc.) internet connection through your private VPN server instead of your internet service provider (ISP). This means the data transmitted to the internet comes from the VPN and not from your computer. When you browse something on the internet, the VPN acts as an intermediate as you establish a connection with internet. This hides your computer’s IP address thereby protecting your identity from malicious attackers. For example, if you browse Netflix through the UK based VPN connection, Netflix will see your connection coming from the United Kingdom.

Basic Functions of a private VPN network:

  • Secure Your Device
  • Provide Accessibility to Websites and Apps
  • Enables Anonymous Browsing
  • Avoid Throttling

Types of VPN

There are several types of VPN provided by network administrators.

  1. Standalone VPN

Standalone VPN service is popular among homes and small businesses. This VPN service type uses an application that forms an encrypted connection to the private network. You can then use this connection to connect the internet on a large scale.

  • Router VPN

You can enable your VPN connection through a VPN-enabled router. With this VPN type, you can connect several devices to a single VPN connection along with ensuring the protection of all devices. This saves your time of installing VPN individually for each device.

  • Corporate VPN

Large software companies install corporate VPN or remote-access VPN for remote-working employees. This system enables the employees to securely access all the company’s data irrespective of their place of working simply using a password. Corporate VPN need personalized development and large IT resources.
