What is VPN?

A VPN service allows you to secure your site-to-site connections. A virtual private networking system extends a public network over a private one and allows users to transport and receive data over either public or private connections as if their personal computing devices were directly attached to the public network. As an example, you can connect to a VPN service so that you can make secure connections to banking sites, shopping sites, e-commerce sites, and other secure online services. All of these secure connections are possible because the connection is encrypted and protected.

There is a lot of misunderstanding when it comes to what is VPN and how people use them for what it actually is. Many assume that it is used just like a computer in that it allows you to use the Internet through another computer. While this is possible with a basic router, a VPN is much more comprehensive. In fact, it is often used to securely connect two or more independent network locations using the same Internet connection. This is often referred to as a VPN tunnel.

There are two main types of VPN. There is the Open VPN technology and then there is L2TP/IPsec VPN technology. The difference between them is the encryption. The former uses the encryption algorithm as the key. It also uses a random network layer that acts as an encryption key. On the other hand, the latter, L2TP/IPsec, uses a port-key instead as the encryption key but it also uses IP encryption.

Advantages and Disadvantages of VPN:

One of the advantages of VPN is that it provides complete privacy. Private communication is possible even between two individuals using a VPN. You can do this by using VPN services or connecting through a Wi-Fi hotspot. The encryption key is also used when you connect through a Wi-Fi hotspot. There is no need to key in your Wi-Fi network password because VPN does it all for you. This includes encryption and authentication.

Another advantage of a VPN is that it can provide a secure internet connection. As mentioned before, the encryption key is used when you connect to your internet service through a Wi-Fi hotspot. This way, you can make sure that your IP address cannot be tracked or blocked. With the use of a private VPN server, your internet connection will not be subject to any misuse by other users.
