When traveling internationally, using a VPN is crucial to protect your data and ensure secure browsing. Public Wi-Fi networks in airports, hotels, and cafes can be vulnerable to hackers, and using a VPN adds an extra layer of encryption to your connection. A VPN masks your IP address and encrypts your traffic, making it harder for cyber attackers to access your personal information. It also allows you to access region-restricted content and websites that may be blocked in certain countries.
