Which SD-WAN component ensures only authenticated customer nodes join the overlay?

The vBond orchestrator is the initial point of contact for all SD-WAN devices joining the overlay network. It performs authentication and authorization of these devices, ensuring that only trusted and legitimate customer nodes can connect. After successful authentication, vBond facilitates the establishment of secure connections between the devices and the vSmart controllers and vManage NMS. vManage is the network management system, used for configuration, monitoring, and troubleshooting, not initial authentication. vSmart controllers are responsible for propagating routing and policy information, not device authentication. WAN Edge devices are the endpoints that connect to the overlay, but they are authenticated by vBond, not the authenticating component themselves.
