What a VPN Actually Does
What a VPN really routes and hides, and what it does not: the encrypted-tunnel model, who can see what, and when a VPN is mostly theater.
- The Tunnel — What a VPN Really Is A VPN is an encrypted tunnel to a relay server: it doesn't make you vanish, it routes all your traffic through one trusted machine that fetches the internet on your behalf.
- Who Sees What — The Visibility Ledger Exactly what changes when the tunnel is on: your ISP loses sight of your destinations, websites see the VPN's address, and the VPN provider inherits the view your ISP used to have.
- Where the Promises Break The honest part: HTTPS already encrypted your pages, you are not anonymous, and the VPN provider now sees what your ISP used to — when a VPN truly helps and when it's pure theater.
