VPN is Virtual private network. It directs a particular connection to internet through the help of a remote server which is run by a VPN provider. VPN is something that protects the online identity of a network holder. Taking example of any company or an institution network, where the resources and tools are allowed to be used by the restricted users of same network. Any user outside to this network does not have the right to access this network. The data and resources can be accessed by either the employers, employees or any person who are having authority of it. Thus it can be said that NordVPN is a technology which can make one feel that, the concern is connected directly to a private network. This is much about the security perspective as when a private data goes into a public network, there is risk that it may be attacked or stolen. 

Thus when it is security, VPN service becomes most important. There are many benefits of having them such as:

• It is seen that privacy rights have been violated by the major players, they use many data where it is on phones or systems. Thus, a VPN service provider protect privacy in such cases
• Number of sites may be blocked in case were internet is not freely accessed, having such services allows to unblock such blocked websites

With respect to the ways in which it can be used, it can be seen in three ways such as the first one is site to site, that allows access to internal websites from two locations. The second one is a personal VPN which encrypts traffic between a user and the internet. The third way is remote to the office, where clients can be installed on the device of the worker to access the network of the main office.
