Gartner defines global WAN services as points-of-presence (POP)-based services supporting multiregional corporate networks. Service providers own and operate their own global core networks and sell directly to the client. Services include transport-centric/unmanaged, managed, and co-managed network services, or network as a service via a monthly fixed or usage-based fee model. These services are measurable and consumable through customer-facing web portals and programmable APIs. Global WAN services consist of backbone network transport and last-mile access connections, providing connectivity to individual enterprise sites such as large offices or remote branches. WAN service providers are also offering more transformational capabilities, such as cloud fabrics and enhanced visibility enabled by the underlay service network, and adding more network-based security functions to their offerings. Ancillary services such as cloud interconnects, managed SD-WAN and secure access service edge (SASE) are now commonly offered. Gartner also sees providers increasingly investing in AI and automation to support more service processes across the WAN service life cycle, from network design to service assurance.
