High-Performance Virtual Routing and Network Security Software for Telco and Cloud

6WIND develops virtualized networking software that replaces purpose-built routing and security appliances with software running on commodity servers. Its stated customers are communications service providers, mobile network operators, NaaS and B2B telco providers, cloud and data-center operators, MSPs, systems integrators and Tier-1 OEMs. The company operates from EMEA headquarters in Montigny-le-Bretonneux, France, with regional offices in Santa Clara, California and Singapore, and presents itself as a green-technology vendor focused on sovereign, energy-efficient network infrastructure deployable across any cloud or edge environment.

Everything sits on 6WNOS, the core networking stack that turns a standard x86 or ARM COTS server into a multi-terabit router. The Virtual Service Router suite packages that stack as discrete functions: vPE, vCSR, vBNG, vBR, vCPE and vUPF for routing and mobile traffic, alongside the security-oriented vSecGW IPsec gateway, the vFW L3/L4 firewall and vCGNAT for IPv4 exhaustion. Each deploys on bare metal, as a VNF or as a container, with an SR-IOV-accelerated data plane, VRF and ACL segmentation, and APIs for OSS/BSS automation.

A separate Host Network Accelerator embeds routing directly into Kubernetes nodes, covering telco CNF connectivity that Kubernetes does not handle natively, while 6WINDCloud applies the same stack to disaggregated cloud-native network builds. The argument against chassis vendors such as Cisco, Juniper and Nokia is cost, agility and power draw; the company claims its suite lowers energy consumption by more than fifty percent by cutting the servers required. Recent positioning targets AI networking and AI-RAN, including a cloud-native distributed UPF demonstration with Red Hat, Senao Networks and Intel.
