Free Wi-Fi is everywhere. It is available in airports, hotels, cafés, and while it’s incredibly convenient, it often comes at the cost of cybersecurity. A study conducted in 2023 found that a significant number of people had their personal information compromised when using public Wi-Fi in airports and hotels.
This article is not meant to dampen your travel plans, but to help you navigate them securely. By understanding the hidden risks and adopting some smart habits, you can stay connected without putting your data at risk.
Why free Wi-Fi is risky
While free Wi-Fi networks are useful, public networks generally lack the encryption needed to protect your data. This leaves your online activity exposed to anyone with the right tools.
One of the biggest threats is the risk of man-in-the-middle (MITM) attacks. In these attacks, hackers intercept the data you send and receive, gaining access to sensitive information such as login credentials, email conversations, or even financial details. To the user, everything appears normal, but in reality, personal data is being stolen in real-time.
Another danger is fake Wi-Fi networks, often referred to as “honeypots.” Cybercriminals set up these networks to trick people into connecting. These fake hotspots often mimic legitimate ones, using names like “Airport Wi-Fi” or “Hotel Guest Network.” Once connected, hackers can monitor your activity, steal your information, or even install malware on your device.
Stolen data from public Wi-Fi includes passwords for email accounts, online banking logins, and confidential business files. Without taking precautions, the convenience of free Wi-Fi can quickly turn into an expensive mistake.
Safe alternatives to public Wi-Fi
Travel doesn’t have to mean compromising your online security. With a little preparation, you can stay connected without putting your data — or your peace of mind — at risk. Here are safer options to consider instead of relying on public networks:
- Use your mobile hotspot
Most smartphones allow you to create a personal hotspot using your mobile data. This creates a private Wi-Fi network that you can use wherever you go. While it might consume more data, the added security is worth it — especially when accessing work files or personal accounts. - Use a VPN
A virtual private network (VPN) creates an encrypted tunnel for your internet activity, making it invisible to cybercriminals — even on public Wi-Fi. Whether you’re accessing work documents or checking your bank account, a VPN keeps your data secure. Choose a reputable VPN provider and set it up before your trip. - Stick to trusted networks
If you must use public Wi-Fi, opt for password-protected networks from reliable sources such as your hotel or an airport lounge. While these networks are generally more secure than open ones, you should still be cautious. Avoid handling sensitive transactions, such as banking, even on trusted networks.
Tips for staying safe while travelling
Cybersecurity while travelling is about forming smart habits. By staying vigilant, you can enjoy your trip without making yourself an easy target for hackers. Here’s how:
- Be mindful of your surroundings
If you’re working in a public space, watch out for shoulder surfers who may be looking at your screen. - Disable auto-connect
Many devices automatically connect to available Wi-Fi networks, making you vulnerable. Turn this feature off and select networks manually. - Avoid sensitive transactions
Public Wi-Fi is not the place for online banking or handling sensitive accounts. If it’s not urgent, wait until you’re on a secure connection. - Keep your devices and software updated
Before travelling, install the latest security patches and updates to protect against vulnerabilities. - Log out of accounts
Once you’re finished using an app or website, log out to minimize risks if your device is compromised. - Enable device tracking and remote wipe
Prepare for worst-case scenarios by activating “Find My Device” features and remote wipe capabilities.
Explore the world without unnecessary risks
Travelling should be about adventure, connection, and exploration—not cybersecurity worries. By making a few smart choices, such as using a VPN, staying vigilant on public Wi-Fi, and keeping your devices updated, you can focus on what truly matters while keeping your data safe.
Good cybersecurity habits allow you to explore both the physical and digital world securely. Protecting yourself doesn’t have to be complicated—small, thoughtful steps at every stage of your journey can go a long way.
