Frequently Asked Questions — GTT Communications vs Lumen Technologies
What is the difference between GTT and Lumen for global networking?+
Both are global Tier 1 network providers, but differ in scope. GTT focuses on IP transit, MPLS, and SD-WAN across 600+ PoPs on 6 continents — primarily selling to carriers and multinationals. Lumen offers a broader portfolio including MPLS, SD-WAN, edge computing, connected security, and CDN alongside its fiber backbone. For pure global IP transit, GTT is competitive; for managed enterprise WAN with additional services, Lumen is broader.
Is GTT or Lumen better for MPLS?+
Both offer carrier-grade MPLS. GTT is strong in European MPLS markets and for carriers needing global private networking. Lumen's MPLS platform is well-established across the US and 60+ countries, with a long enterprise track record. For US-centric enterprise, Lumen may have deeper account support; for European or carrier-grade MPLS, GTT is highly competitive.
Do GTT and Lumen compete for the same customers?+
Yes — both target enterprise and carrier buyers for global WAN, MPLS, and IP transit. They often appear on the same RFPs. GTT typically positions on Tier 1 IP transit pricing and European reach; Lumen positions on managed services breadth and US enterprise depth. In practice, many large enterprises have both in their multi-carrier WAN.
