⚠️ Public WiFi Risks Are Real
Anyone on the same network can potentially intercept your traffic. Hackers set up fake hotspots with names like "Starbucks_Free" to capture data. Hotel WiFi is notoriously insecure. Don't use public WiFi without protection.
How Public WiFi Attacks Work
Evil Twin Attack
Hacker creates a fake network with the same name as the legitimate one. Your device connects to the fake, and all your traffic flows through the attacker.
Man-in-the-Middle (MITM)
Attacker positions themselves between you and the network. They can see, modify, or inject content into your traffic.
Packet Sniffing
With simple software, anyone on the network can capture unencrypted data packets—including login credentials sent over HTTP.
Session Hijacking
Attacker captures your session cookies and uses them to access your accounts without needing your password.
How VPN Protects You
A VPN creates an encrypted tunnel between your device and the VPN server. Even if someone intercepts your traffic, they see only encrypted gibberish.
❌ Without VPN
- • Traffic visible to network admin
- • Other users can sniff packets
- • Fake hotspots capture everything
- • Session cookies can be stolen
✓ With VPN
- • All traffic encrypted
- • Packet sniffing sees only encrypted data
- • Fake hotspots can't read your traffic
- • Session data protected
High-Risk Public WiFi Locations
Coffee Shops
Starbucks, local cafes. High traffic, easy for attackers to blend in. Multiple fake networks common.
Airports
Travelers are distracted and in a hurry. Prime target for credential theft.
Hotels
Often poorly secured. Business travelers with valuable data. Shared networks across rooms.
Libraries
Free, open networks. Often no password. Easy access for anyone.

Frequently Asked Questions
Is HTTPS enough protection on public WiFi?
HTTPS encrypts data between you and the website, but DNS queries, metadata, and which sites you visit are still visible. VPN provides complete protection.
Can I use mobile data instead of public WiFi?
Yes, mobile data is more secure than public WiFi. But VPN is still recommended for privacy from your carrier and on networks abroad.
What if the captive portal doesn't load with VPN?
Disconnect VPN, connect to WiFi and accept terms, then immediately enable VPN before browsing. Some VPNs have split tunneling to handle this.
Stay Safe on Any Network
Protect yourself at coffee shops, airports, and hotels. Both VPNs offer 30-day money-back guarantees.
