What is a VPN and how does it work?

Understand the VPN route, which IP websites see, what HTTPS still does and how to choose a VPN for your device and everyday browsing.

Start here

Choose a VPN with a device-and-plan checklist, privacy questions, real-world trial steps and a simple way to compare your shortlist.

Understand free tiers, trials, subscriptions and bandwidth sharing, with an allowance example and questions to ask before signing up.

Follow the path of a VPN and a proxy request, understand HTTPS, and distinguish your VPN connection from Zenshield’s bandwidth-sharing role.

Understand where HTTPS encryption ends, what a VPN adds, and why a VPN does not make an unsafe website trustworthy.

Compare local browsing history with network privacy, then choose the controls that fit the information you want to protect.

Check your public IP before and after connecting, understand unchanged or unexpected results, and know what an IP lookup cannot establish.

Choose a VPN, another permitted network or an ISP change based on the address you need to change, then verify the result.

Compare public IP, DNS and WebRTC observations, then test the app you use. Learn what each result establishes and what to investigate next.

Compare protocol support, connection reliability and network restrictions without assuming one protocol wins on every device.

Understand the World Bank indicators, missing observations, timezone references and licenses behind Zenshield’s country and regional guides.

Review router access, Wi-Fi encryption and connected devices, then decide what a VPN can add to your home connection.

Understand tracking pixels and tagged links, change your email privacy settings, and know where a VPN does and does not help.
