Virtual Private Networks act as a secure tunnel that safely connects the user to a remote network across a public network.
- Thanks to VPNs and the abundance of cheap Internet bandwidth, companies no longer have to lease dedicated lines to connect 2 remote locations. Instead, they can establish a secure encrypted channel which can safely transfer data between both locations across the Internet.
- Another common use for VPNs would be for laptop users who want to connect to corporate systems from remote networks. These can include coffee shops, airports, hotels and other places where network security might not be the most reliable. In order to gain secure access to servers on the internal network, these employees will need to install VPNs onto their laptops.
