NEXCOM’s esaf Platform Manager uses AI to learn each device’s normal connection patterns and monitor real-time anomalies, showing intuitive three-color alerts for normal, warning, and critical statuses. It is ideal for critical machines with stable environments.
OT Security
The Rising Importance of OT Security
As industries move from 3.0 to 4.0, connected factory equipment faces unprecedented cybersecurity risks. OT Security protects industrial control systems, ensuring operational continuity and safety. The Toyota Motors plant attack, which shut down all 14 domestic factories and caused a loss of 13,000 vehicles, highlights these real-world threats. Countries worldwide are also introducing regulations like IEC 62443 and the NIST Cybersecurity Framework to strengthen OT security.
Use Cases
Deadly Tumors in OT Security
In modern industrial environments, OT security teams face an unrelenting battle. Massive streams of control commands, packets, and device connections pour in every second, overwhelming traditional rule-based systems. False alerts spike during maintenance, line changes, or equipment repairs, consuming precious time and manpower. These relentless challenges act like malignant tumors, slowly eroding efficiency and spreading through the organization just like a deadly cancer.
Severe Consequences
OT security breaches can cause financial loss,
operational disruption, safety risks,
and theft of critical IP.
False Alerts
Rule-based detection often triggers false alerts
during maintenance or line changes,
demanding heavy human effort to resolve.
Data Overload
Industrial systems generate massive signals per second,
including commands, packets, connections,
and sensor data.
Talent Shortage
Skilled personnel are limited as OT security is highly specialized, routine-heavy, and difficult to master.
AI Could Be Your Ultimate Scalpel
As AI technology matures, it becomes the ultimate remedy for the headaches OT security teams face. Like a precise surgical scalpel, AI can remove the malignant tumors of OT Security one by one, taming overwhelming data volumes, eliminating the frustrations of rule based blind spots, and addressing chronic talent shortages. Below are four ways AI is ideally suited for OT Security and how it solves these critical challenges.
Ideal for OT
Industrial OT environments are structured and M2M driven, making AI highly effective in their regular and predictable patterns.
Alleviate Talent Shortage
By reducing manual workload, fewer engineers are needed, freeing staff to focus on higher-value tasks.
Save Time
AI can analyze rule-based alerts within seconds, learning from historical data, instead of engineers spending hours interpreting each alert.
Lower Security Barriers
AI language models help staff, even those with limited cybersecurity expertise, understand alerts, industry knowledge, and recommended actions.
NEXCOM esaf Platform Manager
NEXCOM’s eSAF Platform Manager delivers a powerful, all-in-one OT security solution. Using the eSAF Frontier series, we collect massive real-time data from industrial machines every second and decode diverse industrial communication protocols into structured cybersecurity information, including connection counts, packets, command sets, and system metrics. The platform layers intelligent filtering to detect abnormal behaviors, helping OT security personnel make precise and efficient decisions. Its clean, intuitive UI visualizes on-site OT equipment and supports training and deploying AI models directly. All processing is deployed at the edge, ensuring stable operation even in harsh factory environments. Explore the flow below to see how our eSAF Platform works and discover the AI models integrated into our cybersecurity system.
What AI We Integrate on the Edge
Deep Precision Analysis
Rapid Response Analysis
eSAF Platform Manager provides a pre-trained large language model for rapid response analysis, trained on massive, diverse historical machine data. It detects abnormal connection counts and is ideal for production lines that frequently change, enabling quick deployment without additional training.
Cybersecurity & Query Assistant
NEXCOM’s messaging bot integrates two AI assistants: a fine-tuned LLM for expert cybersecurity guidance and multi-turn tracking, and the eSAF Query Assistant for real-time natural language queries on alerts, IPs, and ports, streamlining security management and decision-making.
eSAF UI for OT Management
NEXCOM’s esaf Platform connects closed OT equipment and visualizes machine status in a clean, intuitive UI, making it easy to monitor anomalies and apply AI models efficiently.
