NTT DOCOMO BUSINESS and TRANSATEL Launch “Cellular SASE for IoT”

NTT DOCOMO BUSINESS and TRANSATEL announced that they are launching “Cellular SASE for IoT,” a new solution for the global IoT market. This is the first solution of its kind offered by a carrier in Japan. The solution combines NTT’s global MVNO TRANSATEL’S global mobile connectivity with Zscaler’s zero trust security to provide cloud-based security and flexible connectivity for IoT devices and enterprise mobile endpoints, without requiring conventional VPNs or software agents on devices. By using the SIM itself as the foundation for connectivity and security, the solution helps customers strengthen protection while simplifying deployment and operations across borders.

As IoT adoption accelerates, enterprises are connecting vast numbers of devices to networks around the world. At the same time, many IoT devices have limited processing power and storage capacity, making it difficult to implement conventional on-device security measures such as threat detection, access control, and vulnerability response. As a result, these devices are increasingly exposed to cyber risk.

Global deployments add further complexity, requiring support for a wide range of device specifications and country-specific communications environments. Traditional approaches - such as deploying VPNs or installing security software on each endpoint- can be difficult to scale effectively. In response, NTT DOCOMO BUSINESS and TRANSATEL are introducing a new solution that enables secure connectivity between IoT devices, cloud environments, and corporate IT systems without relying on software installed on the devices themselves. The solution also supports multi-carrier path redundancy without requiring separate contracts in each country, helping enterprises centrally manage global IoT and IT environments while minimizing security risks and accelerating digital transformation.

At the same time, many IoT devices have limited processing power and storage capacity, making it difficult to implement conventional on-device security measures such as threat detection, access control, and vulnerability response. As a result, these devices are increasingly exposed to cyber risk.

Leveraging TRANSATEL’s global MVNO network, the solution provides seamless, always-on connectivity across more than 200 countries and territories. TRANSATEL’s proven multi-carrier SIM technology enables stable communications for IoT devices worldwide. In addition, a portal for centrally managing SIMs and mobile lines worldwide significantly reduces customers’ operational burden.

By embedding Zscaler’s Zero Trust Exchange platform into the mobile network, the solution delivers threat prevention and access control for internet access - such as firewall protection, URL filtering, and intrusion prevention (IPS) - at a level comparable to enterprise IT environments. For private access, all traffic is securely routed through the cloud, helping minimize the attack surface while enabling secure, bidirectional communications between IoT devices and users or servers.

By combining the solution with NTT DOCOMO BUSINESS’s managed services (MSP) offering, “X Managed®” , customers can benefit from high-quality centralized support. As a company certified under Zscaler’s MSSP program, NTT DOCOMO BUSINESS provides integrated support across both networking and security.

“Through our expanded partnership with NTT DOCOMO BUSINESS and Transatel, Zscaler is bringing a cellular security solution to the global IoT market. By combining trusted mobile connectivity with zero trust security, this solution will enable customers to scale deployments under consistent policies, reduce their attack surface, and simplify day-to-day operations.” says Nathan Howe, Vice President, Emerging Technologies, Zscaler, Inc.

NTT DOCOMO BUSINESS and TRANSATEL, in collaboration with Zscaler, will continue enhancing the functionality of this solution and expanding its geographic coverage in line with the growth of the IoT market. The companies will focus particularly on supporting secure IoT adoption in manufacturing, logistics, energy, and smart infrastructure, helping customers accelerate digital transformation, automation, and global business expansion
