How TSG Works The following technical analysis examines the software development practices and network hardware operations underlying TSG. While detailed, this information is essential for understanding the system's actual functionality and implementation methods. TSGX: Geedge’s Integrated Hardware Solution The Tiangou Security Gateway is primarily marketed as an integrated hardware solution known as TSGX. Initially, it operated on white-label hardware provided by HP Enterprise and DELL; however, it now utilizes hardware supplied by the Chinese server manufacturer Nettrix, which is a spinoff of the supercomputer manufacturer Sugon. Sugon was sanctioned by the U.S. government for alleged links to the People’s Liberation Arm Image Caption:

Instead of just having one firewall appliance or two for redundancy, TSG-X is able to scale horizontally and the customer can add additional nodes. Each node adds more capacity for processing more internet traffic. The individual nodes are connected together through a network packet broker that load balances the traffic based on the source and the destination. The network packet brokers (NPBs) are hardware appliances, and this data indicates that there are deployments where Geedge has used NPBs from third party vendors like Niagara Networks. Geedge also provides their own product called Ether Fabric, which is described below.
