The Basics of Virtual Private Networks


If there’s one important advancement made on the Internet, it’s the virtual private network or simply called VPN. By definition, the VPN is a private network that utilizes the Internet to connect to users and remote sites.

If, for example, you own a business in various cities, you can use the VPN to efficiently manage your people who are working in different locations. Of course, a fast and secure Internet connection is necessary to achieve this.

What’s probably the most important feature of the VPN is security. As its name suggests, the VPN utilizes a virtual connection that is routed through the web from the company’s private network to the employee or remote site. Anybody trying to intercept an encrypted data can’t, therefore, read it.


Here are the two types of VPNs:

Remote Access

Also referred to as a Virtual Private Dial-up Network or VPDN, this is commonly used by companies who have remote employees who need to establish a connection to private networks. This user-to-LAN connection offers an encrypted connection between the user and the company’s private network. This is often accomplished through a third-party service provider.

Site to Site

A company may connect to various fixed sites over a public network such as the world wide web. A website merely needs a local connection to the same public network. This helps them save more money on long private leased lines.
