If you consume YouTube videos, it’s very likely at some point you’ve had an influencer turn to the camera in the middle of a video then awkwardly present a sponsored ad for VPN software. They often talk about how a VPN protects your privacy and allows you to view content in other countries. But how does VPN software really work from an IT perspective?
VPN stands for Virtual Private Network. If you’ve ever lived in a big city like New York City, you’ve likely taken a ride inside an underground tunnel. Maybe that tunnel ran from your location in Manhattan to your destination in New Jersey. That tunnel is built with reinforced concrete and provides protection from the external elements like water.
A VPN is like a concrete, underground tunnel in that it creates a digital, software-based, tunnel that runs between your computer and a destination computer or server over the Internet. Your Internet traffic travels like a train or car inside the VPN tunnel so your data is protected from outsiders. Instead of concrete, your virtual tunnel is built using encryption.
The problem with some Wi-Fi networks in public spaces is that your data could travel across a network in plain view. So, if a hacker is logged onto that compromised Wi-Fi network, he or she could use software tools to intercept and capture your data as it travels across that open network. A VPN prevents interception and capture of data because the data travels inside that reinforced encrypted VPN tunnel. Additionally, a VPN can mask your sensitive computer details that are normally exposed when you surf the Internet without a VPN, like your IP address and geolocation.
VPN software can be setup easily on your computers and mobile devices, or even on your home Wi-Fi router to protect all Internet traffic that flows out of your home. VPN software is widely available and very affordable. If you travel frequently or use public Wi-Fi networks when out, it is essential that you purchase and install VPN software on the devices that you travel with.
