-
You connect to a VPN app on your device (phone, laptop, tablet, etc.).
-
The app encrypts all your internet traffic—turning it into unreadable data.
-
Your encrypted data is sent to a VPN server in the location you choose (e.g., London, New York, or even Tokyo).
-
The VPN server decrypts your data and forwards it to the website or app you’re using.
-
The website only sees the IP address of the VPN server, not your real location or identity.
Real-World Example
Let’s say you’re in Birmingham and connect to a VPN server in the US:
-
Netflix thinks you’re in the US, so it shows you the American content library.
-
Your ISP (like BT or Virgin Media) can’t see what you’re doing—they only see that you’re connected to a VPN.
-
If you’re on public Wi-Fi, hackers can’t intercept your data because it’s encrypted.
What Does the Encryption Do?
Encryption scrambles your data using advanced algorithms (like AES-256), so no one—not even your internet provider—can read what you’re doing online.
Think of it like sending a locked safe through the internet. Only the VPN server has the key.
What About VPN Protocols?
VPNs use different protocols to secure your data. The most common ones include:
-
WireGuard – Fast and modern (great for streaming and gaming)
-
OpenVPN – Very secure and widely used
-
IKEv2/IPSec – Great for mobile devices
Top VPN services let you choose or automatically select the best one for speed and security.
Why It Matters in the UK
Whether you’re:
-
Streaming geo-blocked content like US Netflix or BBC iPlayer abroad
-
Protecting yourself on public Wi-Fi in London coffee shops
-
Avoiding ISP throttling during gaming or torrenting
A VPN ensures your data is safe and your privacy is respected.
