What a VPN actually does
A VPN, or virtual private network, creates an encrypted tunnel between your device and the internet. That hides your browsing from your network provider and masks your real location. It is not magic — it won't make you anonymous — but it is a solid layer of everyday privacy and a handy way to reach content from other regions.
The five things that matter most
1. Privacy and logging
The whole point is privacy, so start here. Look for a clear no-logs policy — meaning the provider doesn't record what you do — and bonus points if that policy has been checked by an independent auditor. Providers like ProtonVPN go further with open-source apps anyone can inspect.
2. Speed
Encryption always costs a little speed; a good VPN keeps that cost small. If you stream, game, or download big files, prioritise services known for fast, consistent connections, such as NordVPN and ExpressVPN.
3. Streaming reliability
Not every VPN can open every streaming library, and it can change week to week. If this is your main reason for subscribing, read our dedicated VPN for streaming guide before you commit.
4. Devices and ease of use
Check how many devices you can connect at once and whether there's an app for each one you own. Households with lots of gadgets should look at Surfshark, which allows unlimited devices. Beginners often prefer CyberGhost's task-labelled servers.
5. Price and commitment
Headline prices almost always assume a long sign-up. A one-month plan offers flexibility; a two-year plan offers the lowest monthly rate. Decide how long you'll realistically use it, and lean on money-back guarantees to test a service risk-free.
Features worth understanding
- Kill switch: cuts your internet if the VPN drops, so nothing leaks.
- Protocols: the rules that move your data; modern ones like WireGuard are fast and secure.
- Split tunnelling: lets some apps use the VPN while others don't.
- RAM-only servers: wipe all data on reboot for extra privacy.
- Server count and locations: more options usually means less crowding and more choice.
Red flags to avoid
- Free VPNs that don't explain how they make money — your data may be the product.
- Vague or missing privacy policies, or no independent audit.
- Promises of total anonymity. No VPN can deliver that.
