When you access the internet via Wi-Fi, do you think about who might be spying on your data, or even stealing it? If not, you're in the majority—unfortunately. Everyone ought to be using a virtual private network, or VPN, whether it's at a coffeeshop or even at home. Yet when PCMag ran a survey on VPN usage, we found a surprising 71 percent of our 1,000 respondents had never used a VPN at all. Even among net neutrality supporters—who you might think would be better informed on security and privacy issues—55 percent had never used a VPN.
For mobile devices, the situation is a little thornier. Most companies offer VPN apps for Android and iOS, which is great because we use these devices to connect to Wi-Fi all the time. However, VPNs don't always play nice with cellular connections. That said, it takes some serious effort to intercept cellphone data, although law enforcement or intelligence agencies may have an easier time gaining access to this data, or metadata, through connections with mobile carriers or by using specialized equipment.
