Surfboard is a cross-platform network client and VPN manager that provides a graphical interface for establishing secure tunnel connections. It functions as a multi-protocol proxy client and a rule-based traffic router, directing outbound requests to specific proxies or bypassing them based on domain and IP patterns.
The application acts as a connection orchestrator, allowing users to import, organize, and switch between multiple virtual private network profiles and server configurations. It implements various proxy standards to route traffic through remote servers for privacy and access.
The system covers network connectivity through the use of encrypted tunnels and virtual private networking. It manages traffic routing via local proxy servers and dynamic DNS resolution to ensure requests reach the correct remote destinations.
