The Cybersecurity Research Group of Hitachi India (HIL) R&D participated in the Global OT Cybersecurity in Energy Sector (GOTS) 2026 held in New Delhi, where they introduced their fuzzing solution for OT products and conducted a live demonstration of security testing using a Hitachi product. At the venue, they also engaged in strategic discussions and exchanged views with a diverse range of participants, including industry representatives, government officials, utilities, and regulators—regarding the latest trends in OT security, cyber risk countermeasures for critical infrastructure, and vulnerability assessment methods.
Hitachi India R&D Demonstrates Fuzzing Solution for OT Systems
HIL Exhibition booth featuring the fuzzing platform developed by R&D
At the exhibition, the Cybersecurity Research Group of HIL R&D displayed its fuzzing solution designed for operational technology products and industrial communication systems. The team also conducted live demonstrations, which attracted strong interest from energy operators, government organizations, consulting firms, and cybersecurity providers, indicating a growing demand for practical approaches to validating OT system robustness before deployment into critical infrastructure environments.
They presented live security testing of the Hitachi product, showcasing their AI-powered fuzzing technology. This solution supports both hardware-based black-box testing and software-based grey-box testing, enabling the identification of vulnerabilities, protocol weaknesses, unexpected device behaviors, and resilience gaps in industrial control systems. In addition, the system leverages Large Language Models (LLM) to learn protocol specifications from product and standards documentation, generate testing strategies, and create network traffic using the OT protocols. The test progress can be monitored in real time, and the system can generate test reports including network packet captures as evidence.

Conclusion and Future Outlook
By participating in this event, the members of HIL R&D were reminded of the rapid evolution of cybersecurity challenges facing critical infrastructure operators in the AI era. Therefore, it is essential to pursue research into advanced OT security testing technologies, such as the fuzzing solution they demonstrated, and to continuously validate them.
Furthermore, the event reinforced the importance of joint innovation across industry, academia, government, and research organizations to address the cybersecurity challenges of future energy infrastructure. Going forward, HIL R&D will continue exploring collaboration opportunities with organizations in India to address the gaps in security testing and mitigating threats from advanced AI towards critical national infrastructure.
