GTT provides managed firewall and a global network footprint, with particular strength as an MPLS replacement specialist. For enterprises whose legacy MPLS contracts are up — expensive, rigid, and overdue for a rethink — the migration to managed SD-WAN is a project, not a switch flip. GTT's center of gravity is exactly that transition: replacing MPLS with managed WAN and security across a global estate.
GTT delivers managed network services across a global footprint — managed SD-WAN, managed firewall and security, and the transport to back them — with a practiced motion for migrating enterprises off legacy MPLS. The MPLS-replacement specialization is the lead: GTT's value isn't only the running network, it's the migration discipline to get a global enterprise from rigid, costly MPLS to flexible managed WAN without breaking connectivity along the way.
Organizations with expiring or costly MPLS contracts that need a specialist to run the migration to managed SD-WAN and firewall.
If you're stitching together regional carriers and want one managed global network and security partner, GTT's footprint fits.
If direct cloud connectivity over a carrier-owned backbone is the priority, Lumen's owned-network model is worth a direct comparison.
If the requirement is LTE/5G edge for branches, vehicles, or remote sites, Cradlepoint's wireless-first approach is the better shape.
