You may need to access your funds through online banking when traveling abroad. However, conducting transactions over the Internet can be risky. Also, you might be tempted to access your bank account with free public WiFi.
Regardless of what you are doing online, protecting yourself with a Virtual Private Network (VPN) is advisable. It will encrypt your traffic and route it through a private server of your choice. This means nobody can see your activities, and your banking data will be safe from cybercriminals.
