Here’s a complete guide on VPNs, how they protect you, and how to set up and use them.

What is a VPN?

A Virtual Private Network (VPN) is a tool that encrypts your internet connection and hides your IP address, ensuring privacy and security while browsing the web. When you use a VPN, your internet traffic is routed through a secure server, making it difficult for hackers, governments, or internet service providers (ISPs) to track your online activity.

How a VPN Protects You

Encrypts Your Internet Traffic – Prevents third parties (ISPs, hackers, advertisers) from monitoring your online activity.

Hides Your IP Address – Masks your real IP, making it harder for websites to track your location.

Bypasses Geo-Restrictions – Allows access to region-locked content (e.g., Netflix, YouTube, or social media platforms in restricted areas).

Prevents Bandwidth Throttling – Stops ISPs from slowing down your internet speed based on your online activity.

Protects Against Cyber Threats – Some VPNs offer malware protection, ad-blocking, and other security features.
