Using public wifi without a VPN (a virtual private network)? If you are not using one—you should be.
Perhaps Kashmir Hill says it best:
. . .a VPN is like a condom for Internet use. When you use a VPN, it creates a private encrypted tunnel that your Internet requests are sent through, re-routing your activity through a server controlled by your VPN provider rather than over a shared wifi network. That way, a tech-savvy interloper can’t use sniffing tools to see you connecting to websites or loading apps. Without a VPN, that information can be up for grabs — and if the websites or apps don’t use SSL encryption, a hacker could see everything you click on or send.
Be warned: VPNs are not a one-stop security shop. “If someone really wants to get at what you have, there are tons of ways for them to do it,” explains Jennifer Golbeck, a computer scientist and world-renowned internet security expert at the University of Maryland, College Park. A VPN service improves your online privacy, but it’s not bulletproof protection against hackers, and it certainly won’t make you totally anonymous (as so many services claim). Golbeck describes a VPN as “absolutely the first priority if you’re on public WiFi,” though she notes that it’s most effective when used in conjunction with other common-sense security measures, such as an online backup service and a solid password manager.
