The 
Prisma SD-WAN
 ION 2000, designed for the enterprise branch, transforms legacy wide area networks (WANs), enabling you to combine heterogeneous underlying transports into a unified hybrid WAN. It establishes service-level agreements (SLAs) for security, path selection, and application performance. It helps gain direct insight into end-user application performance for traditional, SaaS, modern, and encrypted applications.
ION 2000 participates in a bi-directional communication with the Prisma SD-WAN controller, enabling configuration of devices, applications, and WANs, providing analytics on devices and applications.
You can deploy the 
ION 2000
in a standalone fashion without a data center device, enabling granular control and visibility for direct-to-internet deployment scenarios, or in conjunction with ION 7000 or ION 9000 in the data center, creating a secure, full-mesh fabric across the WAN.

Used, but in excellent shape.
Comes with Orange USB/CAT adapter and server rail extensions
