Firewalls acts as the security all for the sharing of data from a particular online system.
VPN provides the same security like private networks but at considerably lower costs.VPN is majorly used due to its security features. The security loop holes present on systems today can’t be ignored just like that. We have the whole economy dependent on technology today. A minute error and breakthrough in the data store can cause serious damage to all the connected services. There is a term called deep packet inspection in this ever-growing virtual world which has tormented the present security provisions.

Privacy invasions by search engines to conclude a users surfing habits can also be thwarted by using VPN services. VPN services facilitate their users with unique gateway cities where the assigned Internet Protocol address of the system is located. This way you can access websites which are available for a particular group of users in a certain state. This service is helpful for all those who require travelling from one country to another on regular basis. This way they can carry their authentication to access websites wherever they go. The most common reasons why VPN should be used are like:
- It enables easy routing of the services over the internet by the million users who access it at a given point in time.
- It protects the data from external threats coming from the other systems connected to the same network.
