en.Wedoany.com Reported - NTT DoCoMo and Transatel have jointly launched a secure connectivity service for IoT devices, which achieves secure connections based on SIM cards without the need to install traditional VPNs or endpoint security software.

This service, named "Cellular SASE for IoT," combines Transatel's global mobile virtual network operator (MVNO) connectivity platform with Zscaler's zero-trust security architecture to form a Secure Access Service Edge (SASE) offering. The two companies claim that this product is designed to address the growing challenges enterprises face when deploying connected devices at scale, and is the first service of its kind delivered by an operator in Japan.

Many IoT devices have limited computing resources and cannot run traditional security software for threat detection, access control, and vulnerability management. At the same time, enterprises need to manage a large number of devices distributed across multiple countries and different mobile networks.

Instead of installing security software agents on individual devices, this service uses the SIM connection itself as the security foundation. Traffic is routed through Zscaler's cloud security platform, enabling access control, threat defense, and internet security policies to be enforced before communications reach enterprise applications or cloud resources.

The service consists of three components: Transatel provides global cellular connectivity through its MVNO platform, supporting deployment in over 200 countries and regions, along with centralized SIM management capabilities; Zscaler offers a zero-trust exchange platform for firewall protection, URL filtering, intrusion prevention, and secure private application access; NTT DoCoMo serves as the system integrator and managed service provider, offering deployment assistance and ongoing operational support.

The two companies stated that the service also supports multi-operator connectivity, eliminating the need for customers to negotiate individual contracts in each country, which helps simplify global IoT deployment and enhance network resilience.

While SASE platforms have traditionally been primarily aimed at enterprise users and branch offices, vendors are increasingly applying such architectures to connected devices, industrial systems, and machine-to-machine communication scenarios.

Nathan Howe, Vice President of Emerging Technologies at Zscaler, noted: "By combining trusted mobile connectivity with zero-trust security, this solution will enable customers to scale deployments based on consistent security policies, reduce attack surfaces, and simplify daily operations."
