VPN serviceWhat do you mean by VPN? Well, VPN stands for Virtual Private Network. With the help of a VPN service, you will be able to create a secure connection while accessing internet from a public network. Moreover, you will be able to access websites that are blocked in your region. You will also be able to protect your browsing history from prying eyes, especially when you are accessing internet from a public Wi-Fi. 

The best thing about VPN is that you will be able to access the resources that are part of a private network. You will be able to access the resources remotely. Moreover, you will not have to worry a lot about the internet censorship at all. You need to know that most operating systems have integrated VPN service.


What is a VPN?

When you connect to another computer or device via VPN, you will be part of the local network immediately. Your network traffic will be managed by a secure connection from that point onward. Since you are on the local network after connecting via VPN, you will get access to the sensitive files and resources that are part of that local network. As an example, you can think of an employee accessing the secure files located in the centralized server via a VPN service. As you can see, companies have maximum use when it comes to VPN. Even if you are on the other half of the globe, you will still be accessing the resources as if you are part of the local network. 

When you access the internet via a VPN service, it will create an encrypted VPN connection for you. The VPN will forward a request for you to the centralized server and it will take care of the communication in a secure manner. To make you understand, we can just take the example of Netflix. Until recently, Netflix was not available in many countries and using a VPN service, you could have easily accessed Netflix irrespective of the local restrictions.


Uses for VPNs

Even though VPN is meant to be a simple tool, you will be able to use them for a variety of purposes.

With the help of a VPN service, you will be able to easily access the files from your office, in a secure manner even when you are travelling.

Access home network while travelling: The same can be said about home network as well. You are constantly travelling and you have to use your home network in a secure manner.

You can effectively prevent this with the help of a VPN service.
