An enterprise working across borders and carriers has to keep its infrastructure available and its data confidential, and still see inside its own network. Hub-and-spoke VPNs cannot do both: they add a single point of failure and fall over when one carrier congests. This architecture converges Layer 2 segmentation, an encrypted peer-to-peer mesh, and a SIEM pipeline carried entirely inside that mesh - so the security telemetry never leaves the encrypted path or touches a third party's infrastructure, and isolation can happen automatically at the edge.
