🔹 How a VPN Works & Its Benefits for Remote Work

1️⃣ What is a VPN?

A VPN (Virtual Private Network) is a secure connection between a user’s device and the internet. It encrypts data and routes it through a private server, masking the user's IP address and ensuring privacy, security, and anonymity.

2️⃣ How Does a VPN Work?

📌 Step-by-Step Process:
1️⃣ User connects to a VPN server (e.g., from home to a company’s network).
2️⃣ VPN encrypts the data before sending it over the internet.
3️⃣ Data travels securely through an encrypted tunnel to the destination server.
4️⃣ The VPN server assigns a new IP address, masking the user's real location.
5️⃣ Data is decrypted when it reaches the final destination.

🔐 Key Technologies Used in VPNs:
✔ Encryption Protocols: AES-256, IPSec, OpenVPN
✔ Tunneling Protocols: L2TP, PPTP, WireGuard
