What is a VPN?
A VPN (Virtual Private Network) is a service that lets you access the web safely and privately by routing your connection through a server and hiding your online actions.
But how does it exactly work?
How Does a VPN Work?
Here’s how a VPN works for you, the user. You start the VPN client (software) from your VPN service. This software encrypts your data, even before your Internet Service Provider or the coffee shop WiFi provider sees it. The data then goes to the VPN, and from the VPN server to your online destination — anything from your bank website to a video sharing website to a search engine. The online destination sees your data as coming from the VPN server and its location, and not from your computer and your location.
When you use a VPN service, your data is encrypted (because you’re using their app), goes in encrypted form to your ISP then to the VPN server. The VPN server is the third party that connects to the web on your behalf.
The destination site sees the VPN server as the traffic origin, not you.
No one can (easily) identify you or your computer as the source of the data, nor what you’re doing (what websites you’re visiting, what data you’re transferring, etc.).
Your data is encrypted, so even if someone does look at what you’re sending, they only see encrypted information and not raw data.
As you would imagine, such a scenario is much safer than connecting to the web the traditional way
