More About GTT Communications
GTT Communications provides network and managed services used by enterprises, cloud-native businesses, and service providers that require IP transit, global connectivity, and managed Wide Area Network (WAN) capabilities. Its services are positioned as carrier-grade offerings that connect corporate locations, data centers, cloud regions, and internet endpoints over a global IP backbone and a portfolio of access and transport options. Typical enterprise use cases include hybrid WAN, SD-WAN overlay across multiple underlay transports, secure remote access, and interconnection to cloud and Software-as-a-Service (SaaS) platforms.
The company operates a global Tier 1 IP backbone (network connectivity), delivering internet access and IP transit with routing based on standard internet protocols such as Border Gateway Protocol (BGP) for interdomain routing and IPv4/IPv6 support. Enterprises and carriers use this backbone for upstream connectivity, peering, and distributing latency-sensitive and bandwidth-intensive applications. GTT also offers Ethernet, wavelength, and private line services (network transport) that support point-to-point and point-to-multipoint architectures, often used for Data Center Interconnect (DCI), storage replication, and transport of real-time applications.
Within the enterprise WAN domain, GTT provides managed SD-WAN services (enterprise networking), typically built on software-defined overlay technologies that centralize policy, routing, and traffic steering across multiple access types, including internet, Multiprotocol Label Switching (MPLS), and broadband. These SD-WAN deployments commonly integrate application-aware routing, Quality of Service (QoS) policies, and centralized orchestration, enabling enterprises to implement hub-and-spoke, full-mesh, or hybrid topologies. Traditional MPLS-based VPNs remain available for organizations that require deterministic routing and traffic separation in conjunction with or as an alternative to SD-WAN.
Security services are available as managed options that align with secure access and secure connectivity models (network security). These services often include integrated firewalling, threat protection, and secure remote access applied at the network edge or in conjunction with SD-WAN deployments. This positioning fits reference architectures where networking and security functions converge, such as Secure Access Service Edge (SASE) models, with traffic inspection and policy enforcement embedded in the connectivity layer.
GTT complements connectivity with professional and managed services (managed services), covering network design, migration, and life-cycle operations. For enterprise technical stakeholders, the company is typically evaluated in categories such as global IP transit, SD-WAN and managed WAN, Ethernet and optical transport, and managed network security. In multi-provider architectures, GTT services may interoperate with cloud provider backbones, internet exchanges, and third-party access partners, forming part of a layered connectivity approach that separates underlay transport from overlay control and security services.
