Defguard Client

The desktop client provides a graphical interface for configuring and monitoring WireGuard VPN connections. It can connect to any WireGuard server and also integrates with Defguard VPN & SSO instances, displaying real‑time charts, logs, and connection statistics. Users can manage multiple VPN tunnels and switch between different locations within a single application.

A distinguishing feature is the support for true multi‑factor authentication. When paired with the open‑source Defguard server, the client combines TOTP or email codes with WireGuard pre‑shared keys, delivering layered security beyond the standard single‑factor tunnel establishment. The client stores configuration and history locally, allowing administrators to oversee many customer instances and their tunnels from one place.

The application runs on macOS, Linux, and Windows and is built with Rust, Tauri, and React.js for a native‑feel experience. It is released as a stable, open‑source utility and includes documentation for setup, development, and troubleshooting.
