A VPN creates a secure, encrypted tunnel between your device and the internet, masking your IP address and protecting your data from eavesdropping.
Why it matters:
- Protects sensitive information when using public Wi-Fi (coffee shops, airports, hotels).
- Hides browsing activity from prying eyes, including ISPs and hackers.
- Can help access work networks remotely in a secure way.
Pro tip: Not all VPNs are created equal. Free VPNs may log your data, so use a trusted provider — especially for business use.
