The Real Reasons I Tell People to Use a VPN

The Big One: Nobody Else Gets to See What You're Doing

Every time you go online without a VPN, your internet provider can see exactly which sites you're visiting, when, and for how long. So can anyone else sharing the same network, whether that's your landlord's router or the free wifi at your local cafe. A VPN encrypts your connection and routes it through a private server, so all anyone watching sees is scrambled traffic going somewhere else entirely. It's not about having something to hide. It's about not handing your browsing history to a company whose business model is selling data.

Public Wifi Is Where the Real Risk Lives

I get asked about VPNs most often in the context of public wifi, and for good reason. Open networks in cafes, airports, and hotels rarely have proper encryption, which means anyone with basic tools sitting nearby can potentially intercept what you're sending, including passwords and card details if you're not careful. It's the same environment where a well timed phishing link does the most damage, because people's guard tends to drop when they're just trying to check email between meetings. A VPN closes that gap by encrypting your traffic before it ever touches the shared network.

It Stops Companies Building a Profile on You

Your IP address says more about you than you'd think. Sites and advertisers use it to track your location, link your activity across different services, and build a profile they can sell on or use to target you. A VPN masks your real IP address behind the VPN provider's own, which makes that kind of tracking far harder to pull off. It won't make you invisible online, but it takes away one of the easiest tools companies use to follow you around the internet.

The Small Perks Nobody Mentions

Beyond privacy, there are a few practical upsides people don't expect. Flight and hotel prices sometimes shift depending on where a booking site thinks you're browsing from, so switching your virtual location can occasionally save you money. It also means you're not stuck locked out of services you already pay for just because you're travelling. None of these are the main reason to use a VPN, but they're a nice bonus once you've already got one running.

Is It Actually Worth It?

For the cost of a coffee a month, yes, I think it is, especially if you work from cafes, travel often, or simply don't like the idea of your browsing habits being logged and sold. A VPN isn't a silver bullet on its own though. I'd always pair it with a decent password manager and two factor authentication on anything that matters, since those cover the gaps a VPN doesn't touch.
