John C. Dvorak on the need for a VPN when you’re using public Wi-Fi.
I’ve been using various VPNs for at least 15 years, maybe longer. Everyone should be on a VPN. Especially now that they have been perfected and commoditized.
What does a VPN do for you?
In a nutshell, a VPN allows you to use an IP address other than your own and appear to be somewhere other than where you are. The idea was originally dreamed up so work-from-home users could tunnel in to the workplace network as if they were in the office… It turned out that this idea was a good one for other reasons. The most important is that it is difficult, if not impossible, for advanced worm-style malware that can self-install via open ports to ever target your computer. Your machine will appear to be another system someplace else; that other machine is usually a highly protected server and, more importantly, it is not your computer.
VPN’s cost money, but consider it insurance.
