What is a VPN?
Learn how a VPN encrypts your internet traffic to hide your activity from ISPs and advertisers. A simple guide to choosing a provider.
A VPN isn't just for corporate IT departments. It’s a way to keep your internet activity private from your ISP.
Think of it this way: when you’re on a public network or your home Wi-Fi, your traffic goes out into the open. Your Internet Service Provider (ISP) can see exactly which websites you visit, what you download, and how you use the internet. They can build a profile of your habits and sell that data to advertisers. That’s the reality of most standard connections.
A Virtual Private Network (VPN) changes that. It creates an encrypted tunnel between your device and a remote server. Your traffic travels through that tunnel, so your ISP can see that data is moving, but they can’t see where it’s going or what you’re doing. The VPN server then connects to the websites you want to visit. It’s like using a private courier for your digital mail instead of sending it via standard post where anyone can peek at the envelope.
This matters for security, too. On public Wi-Fi—say, at an airport or coffee shop—a VPN helps protect you from snooping. Even on home networks, it adds a layer of privacy that your ISP can’t easily penetrate.
You don’t need to be a tech expert to use one. Services like Proton VPN, Private Internet Access, Mullvad, and TunnelBear are all well-regarded options. Pick one with good reviews, install the client, and you’re covered. It’s a simple step that puts you back in control of your digital footprint.
