The digital transformation of industry has brought new cybersecurity challenges. OT networks (Operational Technology), which traditionally operated in isolated environments, are now connected, exposing them to complex and persistent threats. In this context, traditional monitoring tools are no longer sufficient.
At InprOTech, we developed SANTI, a technology designed to detect threats in OT networks, using strategies such as custom static rules, IDS, honeypots, and the power of artificial intelligence. SANTI provides total visibility, traffic analysis, risk classification, vulnerability scanning, malicious traffic blocking, and proactive protection of critical infrastructures. This technology powers our industrial cybersecurity service, InprOTech GUARDIAN, our comprehensive cybersecurity software specifically designed for industrial environments.
Introduction
The arrival of Industry 4.0 has driven companies to interconnect their plants and industrial systems, exponentially increasing the attack surface. This new connectivity means that industrial control systems such as SCADA, PLCs, or sensors are now exposed to cyberattacks that were previously not possible.
Through our audit processes, we’ve identified an urgent need: current solutions are not adapted to the complexity and specificity of the OT environment. Most of the tools used today fail to provide full visibility, do not adequately prioritize risks, and do not assist technical staff in interpreting critical alerts.
In response, we created SANTI, a native solution for OT environments that allows users to:
- Passively and non-intrusively monitor the network.
- Detect potential threats using proprietary technology, IDS, and honeypots.
- Detect anomalous patterns using AI.
- Classify threats in real time based on impact.
- Manage multiple locations from a single console.
Limitations of the Traditional Approach
Traditional detection and monitoring systems present several key limitations:
- They are designed for IT environments, not OT.
- They do not provide deep visibility into industrial protocols.
- They fail to detect small but critical changes in machine behavior.
- They do not correlate activities between users, devices, and processes.
- They require highly trained personnel for interpretation.
These shortcomings create a critical gap in industrial cybersecurity that SANTI aims to bridge with technologies specifically adapted to the OT environment.
SANTI: An Intelligent Solution for OT Cybersecurity
General Architecture
SANTI operates passively, collecting data through SPAN ports connected to core switches. The captured traffic is sent to a processing system, either local or cloud-based, where artificial intelligence modules analyze the data and generate alerts classified by risk level.
The solution offers an intuitive visual interface that allows security personnel to easily understand the state of the network, identify active threats, and make data-driven decisions.
Main Modules
1. Behavior Analysis with AI
- Modeling of normal traffic: Detects anomalies by comparing current traffic with historical patterns.
- Machine classification by behavior: Groups devices with similar profiles to anticipate generalized attacks.
- User–device correlation: Associates critical actions with responsible users, facilitating audits and intervention.
- Risk scoring system: Prioritizes threats based on their severity and potential impact.
2. Centralized Management and Visualization
- Automatic device inventory: Discovers and lists all assets connected to the network.
- Multi-site consolidated view: Enables monitoring of multiple networks from a single console.
- Smart information filtering: Displays only relevant data to avoid information overload.
- Interactive network maps: Visualizes relationships between devices, traffic, and events.
- Alert history and trends: Analyzes the evolution of threats and behavior of users/machines.
Conclusion
OT cybersecurity requires a new generation of solutions that are truly tailored to industrial needs. SANTI represents that technological leap: it combines AI, big data analytics, and cloud architecture to provide a clear, useful, and actionable view of the threats facing critical infrastructures.
