Public Wi-Fi Is Still a Trap — Here’s the Modern Way to Stay Safe

Public Wi-Fi hasn’t become safer over the years — attackers just became quieter.

Most people still think a VPN is only for “hiding your IP,” but on open networks, a VPN solves three much bigger problems:

🔐 1. Prevents local snooping

Anyone on the same café network can scan devices, attempt ARP spoofing, or harvest unencrypted traffic.

🚫 2. Stops rogue Wi-Fi clones

Attackers create networks like “Starbucks_Free_WiFi” and wait for devices to auto-connect.

🧭 3. Protects app traffic

People assume apps = safe.
Wrong. Many apps still leak metadata, DNS queries, or unencrypted API calls.

⚡ 4. Best practice today

Use:
• a VPN with modern protocols (WireGuard / NordLynx),
• DNS over HTTPS,
• automatic kill switch,
• MFA on key accounts.
