Why You Should Always Use a VPN on Public Wi-Fi
Coffee shops, airports, hotels — public Wi-Fi is convenient but dangerously insecure. Here's exactly what attackers can see and how a VPN protects you.

The Hidden Dangers of Public Wi-Fi
Public Wi-Fi networks at airports, coffee shops, and hotels are notoriously insecure. When you connect to an open network, anyone else on that network can potentially:
- Intercept your unencrypted traffic — see which websites you visit, what you type in non-HTTPS forms
- Perform a man-in-the-middle attack — position themselves between you and your destination server
- Create an "evil twin" network — set up a fake Wi-Fi hotspot with a name like "Airport Free WiFi" to capture your traffic
- Session hijack — steal authentication cookies to take over your logged-in sessions
What a VPN Does
When you connect through Vexonik VPN, all your traffic is encrypted with AES-256-GCM before it leaves your device. Even if an attacker is sniffing the network, they see only encrypted gibberish.
Your data goes:
Your device → Encrypted tunnel → Vexonik server → Destination website
The attacker on the coffee shop Wi-Fi sees:
Your device → ??? (encrypted) → ???
What's Protected and What Isn't
A VPN does protect:
- All HTTP and HTTPS traffic
- DNS queries (no DNS leaks)
- App traffic (email, messaging, etc.)
- Your real IP address from websites you visit
A VPN does not protect against:
- Malware already on your device
- Phishing attacks (you clicking a fake link)
- Tracking via cookies or browser fingerprinting (use a privacy-focused browser alongside your VPN)
Best Practices
- Connect to the VPN before connecting to public Wi-Fi, not after.
- Enable the kill switch in Vexonik settings — this blocks all internet traffic if the VPN connection drops unexpectedly.
- Avoid accessing banking or sensitive accounts on public Wi-Fi even with a VPN, if possible.
- Check the network name before connecting — ask staff for the exact Wi-Fi name to avoid evil twin networks.
Stay vigilant out there.
