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.^[3][4] VyOS can also be optimized to achieve routing at 100Gbps.^[5]

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 the Vyatta Core Edition of the Vyatta Routing software, a small group of enthusiasts in 2013 took the last Community Edition, Vyatta Core version 6.6R1,^[6] and worked on building an open-source fork to continue its legacy.^[7][8] This group founded Sentrium S.L,^[9] a Spanish company, to support and develop the VyOS project.

On Oct 9, 2024, Sentrium SL was acquired by VyOS Networks Corporation,^[10]
