In 2025, online privacy is more important than ever.

🌐 What is a VPN?

VPN stands for Virtual Private Network.
It creates a secure, encrypted tunnel between your device and the internet — hiding your real IP address and data from prying eyes.

🧠 Think of it like:
A private tunnel through the internet where only you can see where you're going.

🔍 How Does a VPN Work?

Without a VPN:

• You connect to the internet directly

• Your IP address is visible

• ISPs and websites can track your activity

With a VPN:

• You connect to a VPN server first

• Your IP is replaced with the server’s IP

• All data is encrypted before it leaves your device

🛡 What Does a VPN Protect?

✅ Hides your IP address
✅ Encrypts your internet traffic
✅ Protects you on public Wi-Fi
✅ Helps you bypass geo-blocked websites (e.g. Netflix, YouTube, etc.)
✅ Prevents ISP tracking and throttling

❗Note: VPNs do not protect you from viruses, malware, or phishing — you still need an antivirus.
