Our 1st blog - Tech security when travelling

Welcome to our very 1st blog - In today's blog we'll give you some tech security tips and tricks as well as why it is great to have a travel data eSIM.

When traveling overseas, protecting your tech and data is crucial. Here are some top security tips:

Tech Security Tips for Traveling:

1. Have "Find My" enabled for users with Apple devices:

   • This allows you to locate your phone/ipad if it gets lost/stolen. A great tip is to purchase air tags for your luggage and wallet - This helps ensure luggage doesn't get misplaced or forgotten.

2. Ensure device PIN, fingerprint/Face ID is enabled:

   • This helps prevent people from accessing your data if you lose your phone and makes the phone less valuable to thieves.

3. Use a VPN:

   • A Virtual Private Network encrypts your internet connection, protecting your data from snoopers on public Wi-Fi networks and allows regional locked apps to function locally and abroad. An example of VPN products are NordVPN, ExpressVPN and Surfshark

4. Keep Software Updated:

   • Ensure your devices have the latest software and security updates to defend against vulnerabilities. 💡 Best done before you travel so you don't burn through your data. 

5. Enable Two-Factor Authentication (2FA):

   • Use 2FA for your accounts. This adds an extra layer of security, requiring both your password and a second form of verification. 💡 Best to use something like Microsoft Authenticator, Google Authenticator or OKTA, this helps prevent needing to rely on SMS based 2FA, which is not as secure.

6. Avoid Public Wi-Fi:

   • If possible, avoid using public Wi-Fi networks. If you must use them, ensure you're connected to a VPN.

7. Secure Your Devices:

   • Use strong passwords and biometric security (fingerprint or facial recognition) to lock your devices.

8. Limit Data Access:

   • Turn off sharing features and only enable necessary permissions for apps.

9. Backup Your Data:

   • Before travelling, back up your data to avoid losing important information if your device is lost or stolen. Great place to backup your data are services such as Microsoft One Drive (part of the Microsoft 365 suite), Google Drive or Apple iCloud

10. Use a Secure Cloud Service:

    • Store sensitive files in a secure cloud service with strong encryption.

11. Turn Off unneeded Location Services:

    • Disable location tracking unless absolutely necessary to prevent unwanted data collection and extra drain on your battery 🔋

12. Be Cautious with Charging Stations:

    • Use your charger, power bank or a USB data blocker when charging in public to avoid data theft. There can be nefarious devices that can extract data via your USB port. Known as "Juice Jacking"
