Imagine leaving your home wearing a clearly legible sign around your neck that provides all of your most important and private information: your name, address, contact information, banking and other financial data, all of your shopping habits, places you frequent and what you do while you are there. Most of us would not want to share this information with complete strangers, for many obvious reasons. This data can put you at risk in any number of ways, including potential theft and physical harm. Yet, that is exactly what many people do every time they use internet.
When individuals and businesses use the internet without encryption they leave all of their information out in the open, and put themselves at great risk. A virtual private network (VPN) can ensure the security of your connections and your most important information. A VPN utilizes a public network (most commonly the Internet) to link distant sites or users. In the past computers had to be connected via hardwiring. A VPN uses "virtual" connections directed through the Internet from the individual or organization’s private network to the distant site or employee location. There are several advantages to using a VPN. As shown above, a VPN can be used to establish a secure connection to a remote network using the Internet. Many businesses use VPNs to enable employees to access to files, software, hardware, and other company resources. Individual users can also utilize a VPN to safely access their secure home network from a remote location.
VPNs are extremely useful to organizations that need to securely connect several networks. As a result, businesses of nearly every size depend on a VPN to connect and share servers and other assets between multiple locations around the world. Individuals can also utilize a VPN to connect their home or additional networks for personal use.
