VyOS Networks has announced VyOS 1.4.4 LTS, a maintenance release of its VyOS Universal Networking Platform intended for deployment in bare metal, cloud, and edge environments. This release targets organizations standardizing on an open-source network operating system for consistency across data center, hybrid, and cloud infrastructure.
VyOS 1.4.4 LTS supports commercial off-the-shelf hardware, major virtual machine hypervisors, and public cloud providers including Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. The update introduces several technical improvements designed for secure operations and refined routing control in production networks. These include:
- Transport Layer Security (TLS) support for syslog, allowing encrypted log transmission to enhance observability and compliance workflows.
- AWS Gateway Load Balancer tunnel handler support, which improves compatibility with Gateway Load Balancer traffic steering and inspection architectures (AWS deployments only).
- BGP (Border Gateway Protocol) policy enhancements, such as matching BGP prefix origin validation extended communities in route maps, supporting more granular Resource Public Key Infrastructure (RPKI)-aware routing decisions.
- More than 50 stability and bug fixes for improved reliability in production deployments.
For upgrade planning, VyOS advises that multicast addresses now cannot be manually assigned to interfaces, and Secure Shell (SSH) Digital Signature Algorithm (DSA) keys are deprecated. Due to upcoming OpenSSH changes, DSA keys will not be supported in future VyOS releases after 1.5, and users are encouraged to migrate to modern key algorithms.
“VyOS 1.4.4 is a practical release focused on secure operations, cloud readiness, and policy control,” said Santiago Blanquet, Chief Revenue Officer at VyOS Networks. “It helps teams run a consistent network OS across environments while improving the security posture and reliability operators need in production.”
