An encrypted tunnel between you and the open internet.

← all visual guides
Why it matters
Encrypts your traffic end to end
Hides your real IP address
Shields you on public networks
Blocks ISP and advertiser tracking

How It Works

  • Connect to the VPN before the internet
  • Encrypt data inside a secure tunnel
  • Let the server act as intermediary
  • Show sites the server IP, not yours

Strong Encryption

  • Rely on protocols like AES-256
  • Make intercepted data unreadable
  • Protect traffic in transit
  • Trust proven cryptographic standards

IP Masking

  • Hide your true IP address
  • Present the server's IP instead
  • Break the link to your location
  • Reduce your exposure to profiling

Public Wi-Fi

  • Encrypt traffic on cafe and hotel networks
  • Defend against snoopers and hackers
  • Secure logins on untrusted links
  • Treat open networks as hostile

Stops Tracking

  • Prevent ISPs from logging activity
  • Block advertisers building profiles
  • Limit cross-site behavioral tracking
  • Drop the connection if data is altered

No-Logs Policy

  • Choose providers that store no activity
  • Leave no records to share or sell
  • Verify independent audits when possible
  • Distrust free, ad-funded services

When To Use

  • Protect privacy on any network
  • Access geo-restricted content
  • Avoid ISP throttling on streams
  • Secure remote work connections
