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.
