I don’t know a lot about security, but I do know that when I use public Wi-Fi—whether on my phone, tablet, or laptop—I should be protecting my traffic with a virtual private network.
For those unfamiliar with VPNs, the concept is basically that you use a simple piece of software to open up a private channel to a trusted server, through which you route all your browsing, email, uploading, and downloading, etc. A good VPN keeps your identity private, your data secure and helps mask your location, even from the provider of the internet connection you’re using to connect to the VPN. Those benefits are highly desirable in today’s privacy-scarce world, and by and large, VPNs are not technically demanding to use. Still, the whole concept of consumer-ready virtual private networks is sorely lacking when it comes to good user experience design.
