Public WiFi is convenient — but it’s also one of the easiest ways to get your data exposed. Coffee shops, airports, hotels… most of these networks are not secure.

That’s where a VPN comes in. But not every VPN is suitable for public WiFi. You need something that balances security, speed, and reliability, not just “privacy features on paper.”

What Really Matters on Public WiFi

When using a VPN on public networks, focus on:

• Strong encryption (AES-256) → protects your data from hackers
• Kill switch → stops data leaks if the VPN disconnects
• Auto-connect → activates instantly on unsafe networks
• Stable connection → avoids dropouts on weak WiFi

👉 Simple insight:
Public WiFi isn’t just slow — it’s unpredictable. Your VPN needs to handle that.

Real-World Experience (Daily Use)

I tested VPNs while working in cafés and airports — browsing, logging into accounts, and using public hotspots.

• With NordVPN:
  Connection was quick, and I didn’t notice any interruptions. It felt “always on,” which is exactly what you want in public.
• With ExpressVPN:
  Slightly smoother when switching networks (WiFi → mobile). Very stable, even on weaker connections.
• With Surfshark:
  Worked well overall, but I noticed occasional delays connecting on crowded networks.

👉 What stood out:
Stability matters more than raw speed when using public WiFi.
