Traditional VPN
Traditional VPN (Virtual Private Network) is a technology that creates a secure, encrypted tunnel over a public network (like the internet) to connect remote users or sites to a private network. It allows users to access resources as if they were directly connected to the private network, ensuring data confidentiality and integrity. Common implementations include IPsec, SSL/TLS, and PPTP protocols.
Developers should learn and use traditional VPNs when building or maintaining systems that require secure remote access to internal resources, such as corporate networks, databases, or development environments. It is essential for scenarios like enabling remote work, connecting branch offices, or securing communications in hybrid cloud setups, providing a foundational layer of network security.
