Public Wi-Fi Security: What a VPN Does and Does Not Fix
Separate real public Wi-Fi concerns from outdated advice, and build a practical connection routine around HTTPS and account security.
These guides distinguish VPN tunnel encryption from the website connection and explain where protocol choices fit. Keep the endpoints separate: a networking label does not by itself describe every application or establish a provider’s business practices.
Use the guides below as a reading path rather than a product recommendation. Follow the primary reference in each article for the point it supports, and use the related links when a question crosses into another topic. Keep your own task and device in view: a useful explanation should help you state what you know and what still needs checking.
