A virtual private network, abbreviated as VPN, is basically a private network that has extension across a public network. It provides the facility of sending and receiving data among various users in a public network, popularly known as the internet. In this arrangement, various devices are connected directly to the private network.

Types of VPN
In earlier times, remote connectivity was provided through leased line connections or modems. These mechanisms cannot be classified as VPNs in the true sense as they provide passive security. As the technology got advanced, fiber-optic networks and digital subscriber line (DSL) was introduced which replaced these legacy mechanisms and private networks based on IP address were introduced. The main advantage which they offered was increased bandwidth in less cost.
VPNs can be either a direct connection between two networks or a remote-access from some location. In a corporate environment, the employees can even access the organization's network if they are at their home or travel somewhere with the help of remote-access VPNs. In fact, a VPN can also be used to connect two similar networks over an entirely different network. Two IPv6 networks can be connected easily through an IPv4 network connection
The classification of VPN systems may be done in a number of ways. They can be classified based on if they provide direct connectivity or remote connectivity, according to the level of security they provide or according to the number of connections they can provide at the same time.
These days life without internet is impossible and accessing the internet through private networks is a necessity in today's fast growing life where the corporate sector has developed so much. The people work as a team irrespective of the geographical locations. The data has to be exchanged over the network within minutes even if the networks are located at remote places. This is the reason that an organizational setup chooses the best VPN subscription. As the data is increased in large volumes across a wide network, there are malicious agents which are always present to hack this data to extract some sensitive information. This open world of the network has to be guarded for safety and privacy, for which the virtual private networks are relied on.
