Choose GTT Communications if:
- ›You need Tier 1 global IP transit with strong European and APAC PoP density
- ›Your organization is a carrier or ISP buying wholesale IP transit
- ›SD-WAN overlay on a global Tier 1 backbone is needed for multi-site WAN
- ›MPLS private networking for multinational enterprise is the primary requirement
Choose Lumen Technologies if:
- ›Managed services beyond connectivity (security, edge compute, NaaS) are needed
- ›You need global reach in 60+ countries with managed MPLS
- ›Edge computing or Network as a Service (NaaS) is part of your architecture
- ›DDoS scrubbing, SASE, or Black Lotus Labs threat intelligence is required
- ›US-centric enterprise WAN with deep account management and support is preferred
Not a Good Fit If…
GTT Communications may not be ideal if:
