About Product VyOS is an open-source network operating system that provides an all-in-one platform for network management. Built on Linux, VyOS integrates powerful routing, firewall, VPN, and network services into a unified system. Unlike traditional networking hardware, VyOS can be deployed on a wide range of platforms, from physical routers and cloud environments to virtual machines, giving users flexibility and control over their network infrastructure.
The key strength of VyOS lies in its comprehensive feature set. It supports dynamic routing protocols (BGP, OSPF, RIP), multiple VPN types (IPsec, OpenVPN, WireGuard), firewall rules, traffic shaping, and more — all configured through a unified command-line interface (CLI) familiar to network engineers. Its ability to scale across various environments makes it popular with organizations seeking open-source networking solutions.
