What exactly is a “VPN”?
A VPN stands for “Virtual Private Network”. It’s software that encrypts everything you send or receive from the Internet so that no one can “listen in” and spy on your traffic. See more technical details on Wikipedia.
Is this people “listening in” actually a big problem?
You betcha! Basically, If you’re connecting to any Wi-Fi network you don’t control, realize that anyone can easily mimic it and listen in on your connection, from Internet service providers to cyber hackers. Say you’re at a coffee shop and you connect to a hotspot called “xfinityhotspot.” Unfortunately there is no way to tell if it’s a genuine hotspot from Comcast/Xfinity or just an imposter looking to sniff out and collect your login and credit card information.
How a VPN works
A VPN encrypts and secures your Internet activity so even if someone is able to listen in, they can’t decode what you’re doing. All they see is scrambled data going by, and they can’t even tell what sites you’re visiting, much less what you’re doing on them.
Most of us are connected to the Internet on our mobile devices, laptops, etc. throughout the day. At this point, if you’re travelling or using public hotspots it’s almost crazy to go on the Internet without a VPN!
But, just like in the real world, not all VPNs are the same. See this article where we talk about the next generation of VPNs – VPNs for Mobility… and why running a conventional VPN on a mobile device isn’t such a great idea.
