Dentsu Research Institute Unveils Nozomi Guardian

Dentsu Research Institute, a leader in integrating technology to facilitate progress in business and society, has announced the launch of the Nozomi Guardian platform starting December 4, 2025. This initiative comes in collaboration with Terilogy, the primary distributor based in Tokyo, which operates under a sales agency agreement. The platform was developed by Nozomi Networks Inc., headquartered in California, USA, and focuses on enhancing operational technology (OT) cybersecurity.

Background of the Initiative

In recent years, the intersection of digital transformation (DX) and operational technologies has become increasingly prevalent across factories and societal infrastructures. As these entities connect their operational systems to external networks, the previously insulated frameworks are now more exposed to cyber threats. While this connectivity boosts productivity and efficiency, it also brings to light fresh cybersecurity challenges that need immediate resolution.

Dentsu Research Institute has proactively set up the DENTSU SOKEN SECURITY TEAM (DSST) to tackle these pressing issues. This group focuses on bolstering cyber resilience across various sectors, primarily concentrating on manufacturing. With extensive experience in consulting on DX rollback and support for system implementations, the Institute has addressed the digital transformation journey in conjunction with operational hurdles requiring focused attention.

The collaboration with Terilogy allows for the provision of Nozomi Guardian, a tailored solution effective in addressing contemporary business needs for enhanced cybersecurity measures in the OT space.

Overview of Nozomi Guardian

Nozomi Guardian is a comprehensive cybersecurity platform specializing in OT and IoT environments. It offers a range of services including asset visualization, vulnerability assessments, anomaly detection, and incident response, all integrated into a seamless user experience. Designed to safeguard industries such as oil and gas, pharmaceuticals, mining, and electricity, the platform provides real-time monitoring that secures industrial assets from potential cyber threats.

Key Features

1. Visualization of OT Assets and Risks
Nozomi Guardian efficiently discovers all devices and communications within the factory network, creating a unified visualization of assets and their communication paths. This continuous monitoring of data flow reveals equipment connectivity and potential risks, ensuring that the previously opaque status of control systems is now transparent, allowing for swift risk identification and management.

2. AI-Driven Anomaly Detection and Real-Time Response
Leveraging artificial intelligence, the platform learns typical communication patterns to identify unusual activities or suspicious communications. It rapidly alerts users about risks that could stem from external cyber attacks, wrongful configurations, or atypical internal behaviors, providing early warning and real-time notifications.

3. Integrated Management of IT and OT Systems
Nozomi Guardian is adaptable to various scales, from single factories to multinational production sites. Supporting a wide array of industrial communication protocols, it easily integrates with existing IT security tools to enable comprehensive oversight of both IT and OT systems, facilitating a harmonious coexistence of these technologies.

Future Directions

Dentsu Research Institute aims to further aid the manufacturing and societal infrastructure sectors in achieving operational stability alongside enhancing cyber resilience. This includes not just technical support but also emphasizes on preparing organizations through training and development initiatives. The goal is to ensure that businesses can maintain continuity and foster sustainable growth in an increasingly interconnected landscape.
