VPN

VPN (Virtual Private Network) is a technology that creates a secure, encrypted connection over a less secure network, typically the internet. It allows users to send and receive data as if their devices were directly connected to a private network, enabling remote access, privacy, and bypassing geo-restrictions.

Also known as: Virtual Private Network, VPNs, VPN Technology, Virtual Network, Secure Tunnel

Why learn VPN?

Developers should learn VPN technologies when building secure applications, implementing remote access solutions, or ensuring data privacy in distributed systems. Specific use cases include securing communications for remote teams, accessing internal resources from untrusted networks, and testing geo-specific features in development environments.
