Keeping Your Info Safe While Traveling

Even at the most cyber-secure airports and airlines, connecting to public WiFi networks comes with a potential risk. Open networks can be convenient for checking flight updates, downloading boarding passes, or streaming during a layover – but they can also expose travelers to data interception and phishing attempts if proper precautions aren’t taken. If you’re hitting the skies soon, be sure to follow these tips to ensure your data is kept as safe as possible while on the go:

1. Connect carefully

Always verify that you’re joining the airport or airline’s official WiFi network, not a lookalike that hackers could use to intercept your data. If a network name seems suspicious or lacks a secure login page, it’s best to avoid connecting altogether.

2. Limit sensitive activity

Public WiFi networks are convenient, but far from private. Avoid signing in to accounts containing sensitive personal, financial, or professional information. Saving those tasks for when you’re able to get a more secure connection can prevent your credentials from being exposed to potential cyber threats.

3. Encrypt your connection

If public WiFi is your only option, turn on a VPN to encrypt your data and reduce risk of hackers gaining access to your information. Keeping your device’s firewall active also adds an extra layer of protection against unauthorized access.

4. Use an eSIM for safer browsing

Instead of relying on shared airport or cafe WiFi when traveling, you can connect through your own private mobile data with a travel eSIM. It gives you immediate, secure access in hundreds of countries without needing to swap physical SIM cards or depend on unprotected WiFi networks.

5. Stay updated

Cyber threats are constantly evolving, and device software updates typically include vital security patches that protect your devices against new vulnerabilities. Make a habit of updating your phone, laptop, and any apps before every trip to keep your digital defenses strong.

Staying online while traveling shouldn’t mean compromising your security, but with the right precautions, you can stay connected confidently – making sure you’re enjoying seamless, secure connectivity across the globe.

In today’s rapidly changing digital landscape, where cybersecurity and identity verification are flourishing, airports and airlines must prioritize stronger, more advanced security measures. Protecting travelers’ data and digital identities isn’t just a convenience – it’s an essential component of modern travel – enabling a safer, smoother, and truly worry-free journey.
