What Is It?
VPNs hide your identity by concealing your IP (Internet Protocol) address and create an encrypted ‘tunnel’ for your data to pass through.
Why Do I Need It?
VPNs can prevent hackers accessing your data through unsafe, public WiFi networks which lack any security on them. Furthermore VPNs can be used to change your location meaning you can access streaming services in countries where they are blocked. Furthermore VPNs use encryption which makes sure all your data is safe.
How Does It Work?
Your client (device) connects to one of many VPN servers which then creates an encrypted link using an encryption protocol to keep the data safe as it travels through the ‘tunnel’

VPNs allow you to change your location, access blocked websites and protect your data, all whilst being legal (in most countries). Ultimately VPNs are very safe if done through trusted providers and are a must have when going abroad.
