As a quick recap, a VPN is a cybersecurity tool you download onto your devices. You can hide your IP address, encrypt internet traffic and protect your browsing history. VPNs even help you get around geoblocking, which refers to content barriers based on where you are in the world. With perks like these, it’s easy to understand why Findstack says 68% of American adults use VPNs. But not all VPNs are created equally — especially the free ones. Here’s why you should never use a free VPN.

Reason No. 1: They put you at risk

One of the main benefits of a VPN is anonymity. With a click of a button, you can cloak your browsing history and pretend you’re somewhere else in the world. For instance, when you use our sponsor ExpressVPN, it just takes a few seconds to reroute your IP address to England, Singapore or even Kazakhstan. A VPN that compromises your privacy is as counterproductive as exercising while eating ice cream. But many free VPNs you’ll stumble upon do the opposite of what they’re supposed to do. Yes, they reroute your IP address, but they also collect your data. Even worse, they might sell it to third parties to make a buck. If you aren’t careful with your choice of VPN, you could do more harm than good. As Kim always says, “If you’re getting something for free, you’re probably the product.”

Reason No. 2: They aren’t very secure

So you know a free VPN is probably harvesting your data. You may not value your privacy, so you shrug that off for the sake of security. But here’s the thing — a free VPN means it might not have the resources to create robust security features. Get this: Some VPNs will actually contain malware. We’ve written in the past about cybercriminals who throw up malware masquerading as cybersecurity apps on the Google Play Store or the App Store. Tap or click here to find out which three iPhone VPN apps are scams. Cybercriminals hope to attract people who want free resources. They’ll create legitimate-looking VPN apps, promising to protect for free. People fall for the trick hook, line and sinker only to find they’re now surfing the web in shark-infested waters.

Don’t think that all VPNs invade your privacy, though

Many premium VPNs actually do what they’re supposed to do. Others, like ExpressVPN, go above and beyond to give you a safe and secure browsing experience. You just need to be wary of the free ones, since they aren’t worth the trouble more often than not. Big Tech corporations are supposed to safely handle our personal online data, but now they’re getting into the political game. Kim doesn’t want to be any part of that and neither should you. That’s why she trusts and uses ExpressVPN. These Big Tech companies match your internet activity to your identity or location by using your public IP address, but with ExpressVPN, no one can see your IP address. No one. Protect your privacy.
