In fact, just after the COVID-19 outbreak, the global usage exploded in the month of March. In March, the COVID-19 was at its peak, and several companies had shifted from office to work from home and that’s where the VPN has played its role. The overall market demand for the consumer in March surged to 41% in the USA. The UK and Australia Virtual private network demand also amplified to an unprecedented level. 

This rapid increase in worldwide demand revealed that VPNs are crucial for online safety. Therefore, in this blog, I will try to explain all the ins and outs of this. We will also discover how that works and how they protect our online privacy. Without further ado let’s start with explaining the VPN itself. 

What is a VPN?

A VPN refers to the virtual private network used to secure your internet connection. This forms a secure tunnel over the internet and enables your traffic to transmit through this protected encrypted tunnel. Moreover, a high-quality service also comprised several security features like military-grade encryption, DNS leak protection, kill switch, and antivirus protection. With the help of its encryption feature, This encrypts all your traffic end-to-end.

Consumer VPNs are the ones that we usually use at home. These VPNs use encrypted tunnels and connect the users with a private network. In this way, all the user data transfers via an encrypted tunnel and remains secure and private with no interception. This is highly functional and leverages its users through various functions.  These are helpful to circumvent geo-blocks and enable users to stream Netflix regardless of the location.

These enable employees to access a company’s network remotely; therefore, This is also known as the remote access VPN. That’s highly secure as they require a secure or one-time password for the employee’s access to the network. Such things are great to resume official activities at home safely. Their functions with a remote access server. Every employee connects with the remote access server on the internet and then securely accesses the internal business network from home. After the global lockdown, This tool has been drastically used worldwide.

How does a VPN work?

After that, you can select any of your preferred server locations and as soon as your VPN connection is established then it starts working. That creates a secure and encrypted connection and uses software to pass your traffic through this newly formed tunnel. The VPN server that you have chosen earlier will now decrypt your traffic and pass it to the open web to get a response to your web request. When the server receives request-response then it again decrypts your traffic and sends back to you securely. Both traffic encryption and decryption are happening under a secure/virtual tunnel and therefore there will be no intervention. 

Their function with multiple servers that spread across the globe. You can select any server location and ultimately your app or client will connect you with the server of your selected region. It will hide your IP address and provide you with a new IP address of your chosen location.
