Let’s learn more about VPNs now. 

What Is VPN & How does a VPN work?

Before understanding how it does what it does, VPN has a few key components which are important for you to understand. The significant key components are a VPN Client, VPN Server, Encryption Protocols, Authentication and a Secure Tunnel.

We would like to break down the connection procedure in a simplified manner. 

  • Open the VPN: You turn on the VPN app on your device (like a computer or phone).
  • Encrypt Data: The VPN makes your internet data secret so others can’t read it.
  • Send to VPN Server: Your hidden data is sent safely to a VPN server.
  • Change IP Address: The VPN server gives your data a different IP address, hiding your real one.
  • Browse the Internet: With the new IP address, you use the Internet privately through the VPN server.
  • Receive Data: When data comes back to you, it goes through the VPN and stays private and secure.

That’s it. That is how a VPN works. 

The Common Types of VPNs You Need To Know

Now, there are tons of options to choose your VPN from. Each VPN serves different needs and scenarios. Here are the most common ones you should know about:

Remote Access VPN

This is absolutely ideal for individual users or telecommuters. This is used when you need to access a corporate network securely from a location which is remote. The way it works is simple. The user connects to a VPN server and then in return, you get provided with a secure access to the organisation’s network. 

Site-to-Site VPN

Used mostly in large companies that have several offices scattered across many geographic locations, this VPN allows them to connect their network resources over the Internet. We will tell you about the two types of Site-to-Site VPNs that are commonly used. One is Intranet-based and the other is Extranet-based. The former connects the Local Area Networks in different locations to each other while the latter allows different organizations to securely connect their LANs, useful for business partnerships.

Client-to-Site VPN

This is quite similar to Remote access VPNs, but a Client-to-Site VPN is often used for connecting a client to a company’s internal network. Once connected, the user can access the network’s resources as if they were physically present and working at the company’s office.

Mobile VPN

Designed for users who need a reliable connection and a consistent internet connection, this VPN works as the user moves between networks like moving g from Wi-Fi to cellular data. This VPN maintains a stable and secure connection and helps in similar transitioning between networks. 

Hardware VPN

Used in a corporate environment a hardware VPN provides secure network connections to the users by creating an encrypted tunnel for data to travel securely over the internet. This device handles every aspect of the VPN connection including authentication, traffic management, and encryption. Since this is embedded in a heart war this VPN offers enhanced security for features and is less susceptible to vulnerability compared to the ones that are software based. Hardware VPNs are mostly used when there is a chance of handling a higher volume of connections making this VPN one of the basic requirements for larger organizations with substantial security needs. 


The abbreviated form of Internal Protocol Security, IPsec VPN used for securing internet communication across an IP network. It encrypts and authenticates each IP packet in a data stream. This VPN operates in two particular modes-transport mode and tunnel mode. 

Transport mode keeps the message in a data packet while tunnel mode encrypts the entire data packet. This dual approach provides a security of a higher level making this VPN the ideal one for creating secure connections between different networks like Side-to-Side VPNs. This includes protocols that establish mutual authentication between agents at the beginning of a session.
