NTT DOCOMO BUSINESS and IIJ Unveil Integrated OT Security Management Solution for Cyber-Physical Systems

TOKYO — July 9 2025 — NTT DOCOMO BUSINESS, Inc. (formerly NTT Communications Corporation) and Internet Initiative Japan (IIJ) today announced an integrated security offering for cyber-physical systems.

Expanded remote operation can expose control networks and introduce risks, but many cyber-physical systems (CPS) and operational technology (OT) security administrators still lack accurate asset inventories and real-time anomaly detection needed to govern access. The new offering combines solutions from OsecT and Safous in a convenient, pre-installed hardware appliance to deliver passive traffic inspection, instant threat alerts, and strictly managed remote access.

Once installed, Safous establishes encrypted least-privilege tunnels for engineers, integrators, or vendors, enforces fine-grained policies, safeguards shared credentials, supports Just-in-Time approvals, and records every session. 

Simultaneously, OsecT taps mirrored OT traffic, maps every device, and flags unauthorized communication, unknown endpoints, or abnormal protocols. As a result, security and operations teams can review IDS alerts alongside access logs to accelerate investigation and response.

Key Features

• OT-Aware IDS: OsecT analyses on-prem OT traffic, inventories devices, and issues live alerts on suspicious activity.
• Secure Privileged Remote Access: Safous restricts users to approved OT applications via a secure portal with credential vaulting, approval workflows, and full session recording.
• Rapid Deployment: Software installs quickly in existing OT environments, reducing integration effort and enabling a faster time to value.

Sales are scheduled to start on September 1, 2025, in Japan and will be handled exclusively by NTT DOCOMO BUSINESS. ASEAN availability to support regional smart manufacturing and industrial cybersecurity initiatives is expected in 2026. NTT DOCOMO BUSINESS and IIJ will continue leveraging their combined network and cloud expertise to safeguard the next generation of cyber-physical systems worldwide.
