VPN for Public Wi-Fi

Public Wi-Fi in cafes, airports, hotels, and coworking spaces is convenient — but inherently insecure. Here are the real risks:

• Man-in-the-middle attacks — an attacker positions themselves between you and the router, intercepting everything you send and receive
• Evil twin networks — a fake hotspot named "Free Airport WiFi" that looks legitimate but captures all your traffic
• Packet sniffing — anyone on the same network can use freely available tools to capture unencrypted data packets
• Session hijacking — stealing your active session cookies to access your accounts without needing your password

These aren't theoretical threats. Security researchers routinely demonstrate them at conferences, and real attacks happen daily at high-traffic locations.

A VPN creates an encrypted tunnel between your device and a secure server. Even if someone intercepts your traffic on a public network, they see only encrypted data — unreadable without the encryption key.

• All traffic is encrypted — browsing, email, messaging, banking — everything goes through the tunnel
• Your real IP is hidden — websites and services see the VPN server's IP, not yours
• DNS queries are protected — your DNS requests go through the VPN, preventing DNS-based tracking
• Auto-connect — ProstoVPN can automatically activate when you join an unfamiliar network

Not every VPN is equally suited for public Wi-Fi protection. Key features:

• Auto-connect on untrusted networks — you shouldn't need to remember to turn on VPN every time you connect to Wi-Fi
• Keep connection — the VPN should automatically reconnect after network loss or device sleep
• Fast connection time — the VPN should establish a tunnel in seconds, not minutes
• Low battery impact — important for laptops and phones when you're out and about

ProstoVPN supports auto-connect and connection persistence. The app reconnects automatically after network changes — switching from Wi-Fi to mobile data and back without dropping protection.
