Public Wi-Fi and VPN Safety
Free Wi-Fi in coffee shops, airports, hotels and libraries is incredibly convenient. But that convenience comes with real security risks. Open networks are easy targets for attackers who can intercept your traffic, steal login cookies, or even set up fake hotspots that look legitimate. Here's how to stay safe when you're out and about.
What makes public Wi-Fi risky?
On an open network, your data travels in plain sight unless it's encrypted. While HTTPS protects your connection to many websites, not everything uses it — and some attacks strip HTTPS down to HTTP without you noticing. Attackers on the same network can run packet-sniffing tools to capture unencrypted data, or launch man-in-the-middle attacks to intercept your logins.
How a VPN helps
A VPN (virtual private network) encrypts everything your device sends and receives, creating a secure tunnel between you and the VPN server. Even on a compromised public network, an attacker only sees encrypted gibberish. This protects your passwords, messages, browsing activity and personal data from prying eyes.
Browse with confidence: A reliable VPN like NordPass includes VPN capabilities alongside its password manager, so you can protect both your credentials and your connection from a single app.
Other precautions to take
Even without a VPN, you can reduce your risk. Turn off file sharing and AirDrop when on public networks. Use your phone's mobile hotspot instead of open Wi-Fi for anything sensitive like banking. Make sure your firewall is active and your operating system is up to date. And always double-check that the network name matches what the venue advertises — attackers sometimes set up "Free Airport Wi-Fi" clones.
Don't forget your passwords
Strong, unique passwords are your safety net even if a session cookie gets stolen. A password manager makes it easy to use a different complex password for every account, so a single intercepted login never cascades into a full compromise.
