Public Wi-Fi networks, such as those in hotels, cafés, airports, and trains, should be treated as untrusted. While many are better secured than in the past, they are still shared networks and require caution.
A zero-trust approach — assuming the network is not secure by default — is the safest way to use public Wi-Fi.
Is Hotel and Public Wi-Fi Safe to Use?
Public Wi-Fi is convenient, but it often lacks the same protections as a private home or business network. Devices connected to the same network may be visible to each other, and traffic can sometimes be monitored if additional protections are not in place.
This does not mean public Wi-Fi should be avoided entirely, but it does mean it should be used carefully.
Common Risks of Public Wi-Fi
Public Wi-Fi can expose users to:
- Traffic interception on unsecured connections
- Fake or malicious Wi-Fi networks designed to look legitimate
- Increased risk if devices are not fully updated or secured
These risks are higher when accessing sensitive accounts or business systems.
How to Use Public Wi-Fi Safely
Use a VPN
A Virtual Private Network (VPN) encrypts your internet traffic and helps prevent others on the network from seeing what you are doing. This is strongly recommended for business users.
Check for HTTPS
Only enter login details on websites that use HTTPS. Look for the padlock icon in the browser address bar.
Disable Auto-Connect
Prevent your device from automatically connecting to nearby Wi-Fi networks.
Keep Devices Updated
Install operating system and security updates before travelling.
Turn Off Sharing and Bluetooth
Disable file sharing and Bluetooth when not in use.
What to Avoid on Public Wi-Fi
- Accessing banking, financial, or healthcare accounts
- Entering payment details
- Logging into sensitive business systems without protection
- Connecting to open networks with no password
Safer Alternatives to Public Wi-Fi
In some cases, it may be safer to:
- Use mobile data or a personal hotspot
- Use a dedicated travel hotspot device
- Watch streaming services directly on hotel TVs rather than personal devices
Modern mobile networks often provide a more secure option for low-risk browsing and email.
