A VPN does far more than hide your IP address. Because it encrypts everything between your device and its server, it becomes a multi-purpose privacy and security tool. Here are the top 10 practical uses — from securing public Wi-Fi to safer gaming.

1. Secure public Wi-Fi connections

Open networks in cafés, airports, and hotels are easy to snoop on. A VPN encrypts your connection so intercepted data is useless to attackers — the single most practical reason to use one. More in our public Wi-Fi guide .

A VPN encrypts your internet connection and hides your IP address — and from those two abilities flow most of its everyday benefits: safety on public Wi-Fi, freedom from ISP tracking, and access to blocked content. Here’s what a VPN can genuinely do for your privacy, and just as importantly, what it can’t.

1. Encrypt your internet connection

This is the foundation. A VPN scrambles all the data between your device and its server, so anyone who intercepts it — a hacker, your ISP, a network operator — sees only unreadable ciphertext. That’s the mechanism behind how a VPN works , and it’s what makes everything below possible.

A VPN kill switch automatically cuts your internet connection the instant your VPN drops — so your real IP address and unencrypted traffic are never exposed, even for a second. It’s the safety net that makes a VPN trustworthy when connections are unstable. Here’s how it works and how to turn it on.

What is a VPN kill switch?

VPN connections occasionally drop — when you switch networks, a server hiccups, or your Wi-Fi stutters. Without protection, your device silently falls back to your normal, unencrypted connection, briefly leaking your real IP address and exposing your traffic. A kill switch prevents this by blocking all internet access until the secure VPN tunnel is restored. (It’s the companion safeguard to the VPN tunnel itself.)

End-to-end encryption (E2EE) means a message is encrypted on the sender’s device and can only be decrypted on the recipient’s device — so no one in between, not even the service carrying it, can read it. It’s the technology behind private messengers like Signal and WhatsApp. Here’s how it works, with a simple example.

What end-to-end encryption means

With most online services, your data is encrypted in transit and then decrypted on the company’s servers — where the provider (and anyone who compromises it) can read it. End-to-end encryption removes that middle access. The keys needed to unlock the message live only on the two devices at each “end.” The service relays scrambled ciphertext it cannot decrypt.
