MPLS WANs were never designed with security, and specifically, threat protection, as a core feature. SD-WAN is forcing network architects to rethink their network security design in the post-MPLS era. The Internet Challenge for MPLS and Hybrid WAN Traditionally, MPLS was always considered a private network.

These drivers, though, also come with baggage: the reassessment of todays corporate security model. Traditionally, Wide Area Networks (WANs) and network security were loosely coupled entities.
