As digital transformation in industrial sites accelerates, cyber attacks targeting OT (Operational Technology) and IoT environments are also surging. In particular, key industrial sectors such as smart factories, power generation and energy, and transportation infrastructure require intelligent security systems that go beyond simple security detection to understand the context of threats and support rapid response decisions. Amidst this trend, 'Vantage IQ,' an AI-based OT security analysis assistant service introduced by Nozomi Networks, a global leader in OT security, is attracting attention from the industry.

Nozomi Networks participated in the '25th World Security Expo & 14th e-Government Information Security Solution Fair (SECON & eGISEC)' held at KINTEX in Ilsan from March 18 to 20, together with its domestic partner 2CSG, and unveiled a next-generation OT security strategy centered on Vantage IQ.

According to materials introduced at the exhibition, Vantage IQ is the world's first personalized OT/IoT security AI assistant that presents a differentiated approach from existing security solutions.

The biggest feature of Vantage IQ is that it is based on a 'private LLM (large-scale language model)' that learns OT assets, communications, vulnerabilities, and threat data within an organization.


It ensures security reliability by performing analysis using only internal data without relying on external data, and provides customized insights optimized for each organization's environment.

Park Ji-yong, the head of Nozomi Networks Korea, whom we met at the exhibition, stated, “Vantage IQ is not a uniform AI, but an AI that understands the situation of the organization.”

According to Branch Manager Park Ji-yong, in terms of actual functionality, Vantage IQ is an OT security operatorShifting the paradigm of Zero from 'notification-centered' to 'decision-centered'.

AI automatically groups hundreds of daily security alerts through correlation analysis and presents priorities based on the actual likelihood of an attack and the impact on processes.

This allows security personnel to focus on core threats requiring immediate action, rather than warnings buried in noise.

Branch Manager Park Ji-yong stated, “The core of OT security is not more alerts, but clearer judgment,” adding, “Vantage IQ predicts abnormal signs in OT networks through time series analysis and deep learning-based normal pattern learning.”

He also stated, “It supports response at a pre-accident stage by learning the normal operation standards of sensors and network traffic and identifying abnormal bandwidth changes or behaviors in advance.”

This is considered a core technology that enables prevention-oriented OT security, going beyond simple detection.

Vantage IQ is also differentiated in terms of user experience.

Branch Manager Park Ji-yong stated, “Users can instantly check asset status, vulnerabilities, high-risk assets, and EOL (End of Life) equipment lists through natural language-based conversations without complex queries or specialized analytical languages.” He added, “Another strength is that it provides ‘board-reporting level insights,’ enabling not only SOC analysts but also managers, CISOs, and executives to understand the same data from their respective perspectives.”

The actual exhibition materials presented various examples of automatically generated reports, such as asset identification reports, high-risk asset tables, and analyses of vulnerable protocol usage.

Based on these technological capabilities, Nozomi Networks is leading the AI-based OT security field in the global market.

Nozomi Networks has recently been recognized for its technological prowess, being named a leading competitor in the AI sector of cyber-physical system (CPS) security in Gartner's AI vendor competition report.

Currently, more than 12,000 customers worldwide are protecting over 110 million industrial facilities through the Nozomi Networks platform.

In the domestic market as well, Nozomi Networks Korea is rapidly expanding its presence, focusing on various industrial sectors such as power generation and energy, manufacturing, and public infrastructure.
