More About NTT Communications
NTT Communications operates as the ICT services arm of the NTT Group, focusing on global enterprises, multinationals, and institutional customers that require integrated connectivity, cloud, and managed services across regions. Its offerings are typically used as foundational infrastructure for corporate networks, mission-critical applications, and hybrid IT environments where organizations combine on-premises (on-prem) resources with hosted and public cloud services.
In networking, NTT Communications provides global IP transit, MPLS-based VPNs, Ethernet, and private connectivity services (networking) to connect data centers, branch offices, and cloud platforms. These services support architectures such as hybrid Wide Area Network (WAN) and SD-WAN-style topologies, where enterprises route traffic over a mix of private and public networks. The company operates and manages large-scale backbone infrastructure and peering relationships, enabling connectivity across major markets and interconnection with internet exchanges and cloud providers.
In cloud and hosting, NTT Communications delivers enterprise cloud infrastructure (cloud infrastructure) with virtualized compute, storage, and network resources, used for application hosting, Disaster Recovery (DR), and workload migration from on-prem environments. Its cloud platforms are positioned for integration with customer data centers and other public clouds, enabling multi-cloud and hybrid-cloud architectures. Standard enterprise technologies such as virtualization hypervisors, load balancers, VPN gateways, and firewalls are commonly associated with these environments, along with APIs and orchestration tools for provisioning and lifecycle management.
The organization also operates data centers and colocation facilities (data center services), providing secure space, power, and cooling for customer equipment. These facilities support direct connections to NTT Communications’ networks and cloud platforms, as well as interconnects to third-party clouds and carriers. Customers typically use these data centers as regional hubs, DR sites, or as part of distributed architectures designed for latency management and regulatory compliance.
Security offerings include MSS, network security, and monitoring (security services). These services can encompass firewall management, intrusion detection and prevention, Distributed Denial of Service (DDoS) mitigation, and security event monitoring, aligned with enterprise security frameworks and compliance requirements. By combining connectivity, cloud, and security, NTT Communications positions itself as a provider of integrated ICT solutions that can be managed under unified contracts and Service Level Agreements (SLAs).
In addition, the company offers consulting, systems integration, and managed operations (IT services), helping enterprises design, deploy, and operate networked and cloud-based systems. This places NTT Communications within marketplace categories such as global networking providers, enterprise cloud and hosting vendors, colocation and data center operators, and managed security and IT services partners, with a focus on large-scale, multi-region enterprise environments.
