NEXCOM’s eSAF Platform Manager uses AI for deep precision analysis, monitoring real-time machine connections and detecting anomalies. It’s ideal for critical machines with stable environments, where using each device’s own historical data ensures accurate alarms.
OT Security
The Rising Importance of OT Security
As industries transition from 3.0 to 4.0, connected factory equipment faces unprecedented cybersecurity risks, making OT (Operational Technology) security an urgent imperative. OT security is the critical defense for industrial control systems, ensuring operational continuity and physical safety. The cyberattack on a Toyota supplier, which led to the shutdown of all 14 domestic factories and a loss of 13,000 vehicles, serves as a stark warning of these real-world threats. In response, countries worldwide are actively mandating regulations like IEC 62443 and the NIST Cybersecurity Framework, proving that robust OT security is now a fundamental requirement for modern industry.
Use Cases
Deadly Tumors in OT Security
When enterprises build OT security systems, they quickly face unavoidable pain points. In modern industrial environments, OT security teams are overwhelmed by massive streams of commands, packets, and connections that traditional rule based systems cannot handle. False alarms surge during maintenance, line changes, or repairs, draining time and manpower. Worse, when intruders break through OT defenses, the impact is catastrophic, bringing disaster level consequences to the enterprise. These challenges are like malignant tumors lodged deep inside the organization, impossible to remove and slowly eroding efficiency 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 is emerging as the true cure for OT security’s hidden tumors. Acting like a precise surgical scalpel, AI cuts away these pain points one by one. It tames the crushing flood of industrial data, clears the blind spots that plague rule based systems, and relieves the strain of limited talent. For OT security teams, AI transforms what once felt like an untreatable cancer into a manageable challenge. Let us show you how AI rewrites the future of OT security.
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 eSAF platform offers two AI assistants fully running on edge. The Query Assistant analyzes on-site cybersecurity data, generates reports, and enables quick natural-language queries for alerts, IPs, and ports. The Cybersecurity Assistant delivers expert answers, interprets complex data, and tracks past conversations to boost problem-solving efficiency.
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.
