VPN has proved to be one of the real advancements of prudence through which several staff members and employees are able to execute work from remote locations. Due to the fact that VPNs route the entire network traffic by means of a tunnel and it so appears that one is resorting to the Internet from some other location, this way one can easily utilise VPN for getting around several few restrictions that are placed on content and websites. (Iqbal, 2019)

The strongest point of a VPN can also be considered as its week in point because the strong encryption that it undertakes is quite time taking and therefore it becomes disappointingly slow at times. In addition, the network complexity increases with the better quality VPN since it uses various network topologies, protocols as well as hardware devices for network creation. (Stewart, 2013)
