What Happens on Unsecured WiFi

These attacks happen every day on public networks

Man-in-the-Middle

An attacker secretly relays and possibly alters communication between you and the website. They can read your emails, steal login credentials, and intercept banking details.

✓ VPN encryption blocks this

Packet Sniffing

Anyone with free tools like Wireshark can capture network traffic on open WiFi. Your passwords, messages, and browsing history become visible to anyone listening.

✓ VPN encryption blocks this

Evil Twin Networks

Hackers create fake WiFi hotspots that look like legitimate ones ("Starbucks_Free" vs "Starbucks Free"). Connect to the wrong one and they control everything you see.

✓ VPN encryption blocks this

Session Hijacking

Attackers steal your session cookies to take over your logged-in accounts — email, social media, even banking — without needing your password.

Protection in 3 Steps

Connect to WiFi

Join any public WiFi network as you normally would — hotel, airport, coffee shop, campus.

VPN Encrypts

Open the app and tap connect. AES-256 encryption wraps all your traffic in an unbreakable tunnel.

Browse Safely

That's it. Bank, shop, email, and browse — nobody on the network can see what you're doing.

Real-World Scenarios

Public WiFi attacks aren't theoretical — they happen to regular people every day. Here are the situations where a VPN changes everything:

The Hotel Traveler

You're in a hotel checking your bank balance before checkout. The hotel WiFi has no password or a shared one posted at the front desk. Without a VPN, any guest on the same network could intercept your banking session. With a VPN, your connection is encrypted end-to-end — invisible to everyone else on the network.

The Remote Worker

You're at a coffee shop working on client files and checking company email. Public WiFi plus sensitive business data is a breach waiting to happen. A VPN ensures your work stays encrypted, meeting compliance requirements and protecting your clients' information.

The Student on Campus

University WiFi connects thousands of users on a shared network. That's thousands of potential entry points for attackers. A VPN protects your personal data, financial accounts, and academic work from other users on the same network.

The Airport Layover

Airport WiFi is notoriously insecure. You're killing time browsing and checking email before your flight. Attackers specifically target airport networks because travelers are distracted and often access sensitive accounts. A VPN makes you invisible to them.

Security Features

Kill Switch

Automatically cuts internet if VPN drops. Your real IP and data are never exposed, even for a split second.

DNS Leak Protection

Ensures all DNS queries go through the encrypted tunnel. Your ISP and network operators can't see which websites you visit.

Dark Web Monitor

Scans dark web databases for your email address and passwords. Alerts you immediately if your credentials appear in a data breach.

Threat Protection

Blocks malicious websites, ads, and trackers. Scans downloads for malware. Works even when VPN is disconnected.

WiFi Security FAQ

Is public WiFi really dangerous?

Yes. Public WiFi networks are inherently insecure because they often lack encryption, and anyone on the same network can potentially intercept your data. Common attacks include man-in-the-middle interception, packet sniffing, and evil twin networks that mimic legitimate hotspots.

How does a VPN protect me on public WiFi?

A VPN creates an encrypted tunnel between your device and a secure server. Even if someone intercepts your data on public WiFi, they see only encrypted gibberish. AES-256 encryption — the same standard used by governments and banks — makes your traffic unreadable to attackers.

Should I use a VPN at hotels?

Absolutely. Hotel WiFi is one of the most targeted networks for hackers because travelers routinely access banking, email, and work accounts. A VPN encrypts all this activity, making it invisible to anyone on the hotel network.

What is a kill switch and why does it matter?

A kill switch automatically cuts your internet connection if the VPN drops unexpectedly. This prevents your real IP address and unencrypted data from being exposed, even for a split second. It's an essential feature for anyone serious about security on public networks.

Can I use a VPN on my phone?

Yes. Apps are available for iOS, Android, Windows, Mac, and Linux. One account covers up to 10 devices simultaneously. Since phones are the primary device people use on public WiFi, mobile protection is critical.
