Vauban

A fortified bastion for privileged access management, built in Rust.

Vauban is an open-source security bastion, developed in Rust, designed to protect and control access to critical infrastructure across enterprise, industrial, and defense environments. Its architecture leverages proven, cutting-edge technologies: privilege separation inspired by OpenSSH and Capsicum sandboxing, a confinement mechanism developed with funding from DARPA (U.S. Department of Defense). The solution includes multi-factor authentication (MFA), role-based access control (RBAC), full session recording, sealed SMTP notifications, and real-time monitoring of SSH, RDP, IACS (industrial tunnel), and MCP connections. Free and sovereignty-friendly, Vauban meets the traceability and audit requirements of sensitive environments while offering an open-source alternative to proprietary solutions.
