Barracuda SecureEdge offers integration with Teridion. Teridion Connect provides numerous PoPs (Points of Presence) across the globe, including China, to allow access to their network backbone. Barracuda SecureEdge can connect to the TCR (Teridion Cloud Router) deployed in one of the PoPs by using IPsec to leverage their backbone to improve connectivity. In addition, BGP can be used as a dynamic routing protocol to learn and propagate networks. For more information, visit the Teridion website.
