Quick answer: VPN stands for virtual private network. It creates an encrypted connection between your device and a remote server, hiding your internet traffic from outsiders and masking your real location.
How a VPN Works
Normally your device connects directly to a website, and your internet provider can see which sites you visit. With a VPN, your traffic first travels through a secure tunnel to the VPN server, which then connects to the website. The site sees the server’s address instead of yours.
What a VPN Can Do
- Protect you on public Wi-Fi: encryption makes it harder for others on the network to spy on your data.
- Hide your browsing from your internet provider.
- Change your apparent location, which can help when travelling.
- Allow secure access to work networks from home.
What a VPN Cannot Do
- It does not make you completely anonymous.
- It does not protect you from viruses or phishing.
- It cannot stop websites from recognising you if you log in.
- It may slow your connection slightly.
Free vs Paid VPNs
Running servers costs money. Some free VPNs earn it by showing ads or collecting user data, which defeats the purpose. A reputable paid service with a clear privacy policy is usually the safer choice.
How to Choose a VPN
- Read the privacy policy, especially about logging.
- Check for independent security audits.
- Look for modern encryption standards.
- Consider speed, server locations and device support.
Using a VPN Responsibly
Always follow the law and the terms of the services you use. A VPN is a privacy tool, not a licence to break rules.

- IP address: the number that identifies your connection online.
- Proxy: a simpler middleman server that usually does not encrypt traffic.
Final Thoughts
A VPN is a useful layer of privacy, especially on public networks. Combine it with strong passwords, two-factor authentication and common sense for real protection.
