  • SD WAN


  • Managed Security Service Provider 
  • Cloud Integrator 
  • Unified Threat Management 
  • Hybrid WAN Architecture 
  • SD WAN Service Provider 


  • NTT’s Tier-1 backbone allows them to offer connectivity options in over 190 regions and countries globally. 
  • The company provides managed SD WAN and managed security services. In addition, they offer other managed services such as: collaboration and productivity, IT, application services, communication lifecycle management and customer experience, making them a good choice for companies looking for an all-round service.
  • Possess 75 secure web gateways (SWGs) worldwide - which extend secure connectivity in remote locations.
  • To address needs for home working solutions, NTT Global supply their own “work from home solution” that issues an LTE enabled SD WAN Router which delivers a variety of use cases. 


  • NTT do not have their own full SASE solution, but they do offer customers comprehensive managed security (See What is the NTT Global SASE Security Solution?). However customers of NTT can access SASE via their vendor partners. 

Netify Review:

NTT Global is an option for clients looking for global managed SD WAN underlay with dedicated internet access (DIA) because of their global Tier-1 backbone, featuring 139 gateways in 52 cities worldwide. They also offer overlay via their SD WAN vendor partners, creating a flexible service that can perform across multiple countries whilst issuing competitive prices for their partner-based services. 

However, caution is advised for companies based in Latin America as NTT’s network coverage in this region is more limited than for other service providers. Further, there is a low brand awareness for NTT outside the Asia Pacific region, which may be off-putting to some clients.

Underlay is provided in the form of their Tier-1 backbone, but overlay is offered via their partners. 

Configuration-Based Key Features:

  • Network Function Virtualisation (NFV): NTT offer clients a wide range of NFV’s, ideal for enterprises looking to transition from traditional hardware technology (for example, uCPE devices as opposed to their hardware counterpart). 103 NFV’s incorporate cloud and virtualisation technologies to create abstract network functions. 
  • Direct Cloud Connect: designed to build a connection between a private network and a public cloud - good for companies looking for a cloud-based or hybrid WAN solution. 

Security-Based Key Features:

  • Secure Web Gateway Service: a security feature designed to filter unwanted malware from user initiated internet traffic. It includes: firewall, IPS, web content filtering, real-time monitoring and malware detection reporting services, delivered from the Global SD WAN platform. 
  • Secure Sockets Layer Virtual Private Network (SSLVPN): creates an encrypted connection over a less-secure network. 
  • IPsec (B2B) Gateways: authenticate and encrypt data packets to provide secure encrypted communication. 

Performance-Based Key Features:

  • Application Performance Management: Monitors application performance and availability, ensuring performance issues are dealt with efficiency. 
  • Predictive Analytics and Automation: Manages the performance of the network whilst detecting faults. 

What is the NTT Global SASE Security Solution?

NTT do not have their own SASE security solution, however clients may be able to obtain SASE via one of their vendor partners. Instead, they offer managed security services, which have a number of key features:

  • Managed Detection and Response (MDR): combines analysis of network traffic with leading endpoint solutions, enhancing threat detection capabilities and decreasing the chances of evasion.

  • Enterprise Security Monitoring: NTT’s SOCs monitor security threats constantly. They provide cloud-based monitoring and response. Clients can choose from either standard tier, or enhanced tier services. Standard tier is suited to companies with more standardised security compliance requirements; and enhanced tier is aimed at corporations with custom security compliance requirements. 
  • Security Device Management: leverages NTT’s global threat intelligence capabilities, and provides consistent updates on devices and applications. Endpoint security solutions are configured to protect against internal and external threats. 
  • Security Operation Centre-as-a-Service: NTT offer their SOCs as a service, which is a fully managed service providing deployment, platform management, detection of cyberthreats, compliance reporting custom use cases, dashboards and incident escalation playbooks. 
  • Web Application Firewall-as-a-Service: detects and denies network-based system attacks. Standard Tier includes management of web application firewall (WAF) policies, denial of service (DDoS) for infrastructure, payment card industry data security standard (PCI DSS) reporting, and automated threat notifications; Enhanced Tier includes the use of a security analyst to detect cyberattacks, best practice and regulatory compliance reporting and custom business compliance reporting.
