VyOS
Linux-based network operating system

VyOS is an open source network operating system Linux distribution based on Debian.

VyOS provides a free routing platform that competes directly with other commercially available solutions from well-known network providers. Because VyOS is run on standard amd64 systems, it can be used as a router and firewall platform for cloud deployments. VyOS can also be optimized to achieve routing at 100Gbps.

Besides being open-source, VyOS also offers subscription-based support, which includes pre-built images for cloud and virtual environments and LTS images for the 1.3 and 1.4 series.

History

After Brocade Communications stopped development of Vyatta in 2013, a group of enthusiasts created an open-source fork56 called VyOS, based on the last community edition, Vyatta Core 6.6R1.7

They founded Sentrium S.L,8 a Spanish company dedicated to providing support and development for the VyOS project. On October 9, 2024, Sentrium S.L. was renamed VyOS Networks Iberia and was acquired by VyOS Networks Corporation, becoming its subsidiary.9
