When you connect from home, a café, or anywhere outside your office, you're using a public network. That's risky. This is where VPN steps in.
It creates a secure, encrypted tunnel between your device and your company network — protecting your data from hackers, leaks, and unauthorized access.

- Encryption
- Authentication
- Integrity
- Tunneling protocols
Understanding these concepts is must-have knowledge for any network engineer today.
