Barracuda SecureEdge Manager allows you to connect SecureEdge to Teridion via BGP over IPsec. 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. For more information, visit the Teridion website.
