In today’s hyper-connected industrial environments, Operational Technology (OT) networks—responsible for managing and controlling physical processes like manufacturing, energy, water systems, and transport—face increasing cyber threats. Despite their critical role, OT systems often lag behind in security maturity compared to traditional IT networks. SG2 Technologies, in collaboration with Pentity, introduces the OT Security Scanner, a powerful solution designed to bridge this gap through non-intrusive, passive monitoring and vulnerability detection.
What is an OT Security Scanner?
An OT Security Scanner is a specialized cybersecurity tool designed to assess and monitor industrial networks and systems such as SCADA, PLCs, DCS, and HMIs without disrupting their operations. These scanners are tailored to the unique protocols and architectures used in OT environments, ensuring both visibility and safety.
The OT Security Scanner from SG2 Technologies & Pentity stands out by offering passive vulnerability scanning—a method specifically crafted to suit the sensitive nature of industrial control systems.
Active vs. Passive Scanning: What’s the Difference?
Understanding the difference between active and passive scanning is key to selecting the right security approach for your OT environment.
🔍 Active Scanning
How it works: Actively probes systems using network requests, port scans, and simulated attacks.
Pros: Comprehensive and often quicker at identifying vulnerabilities.
Cons: Can disrupt critical OT processes or cause unintended behavior in fragile systems.
Best suited for: IT environments or non-critical systems where downtime is tolerable.
🛡️ Passive Scanning (Used by SG2 & Pentity)
How it works: Monitors network traffic without sending any packets. Analyzes behavior, protocol use, and communication patterns to identify vulnerabilities and anomalies.
Pros: Non-intrusive, zero disruption, safe for critical infrastructure.
Cons: May take longer to detect certain issues compared to active scans.
Best suited for: OT and mixed IT/OT environments where stability is paramount.
Key Features of SG2 & Pentity’s OT Security Scanner
Passive Network Monitoring
Safely monitors communication across OT and IT assets, ensuring visibility without interfering with operations.
Vulnerability Scanning
Identifies known weaknesses in industrial control systems and connected IT assets based on protocol behavior and asset fingerprints.
Gap Analysis
Pinpoints misconfigurations, legacy devices, unauthorized connections, and missing security controls across OT and IT layers.
Protocol Awareness
Understands and interprets industrial protocols such as Modbus, DNP3, BACnet, Profinet, and more.
IT & OT Convergence Visibility
Detects hidden pathways between OT and IT networks that could be exploited by adversaries.
Real-Time Alerting & Reporting
Provides actionable intelligence for security teams with prioritized vulnerabilities and remediation suggestions.
Why Choose Passive OT Scanning?
Industrial systems are built for reliability, not cybersecurity. Active probing can crash devices or disrupt operations. The SG2-Pentity OT Security Scanner leverages passive monitoring to:
Maintain operational continuity
Ensure compliance with industry standards (IEC 62443, NERC CIP)
Provide continuous asset discovery and threat visibility
Help meet regulatory and audit requirements
Final Thoughts
As industrial environments continue to digitize, securing OT networks is no longer optional—it’s essential. The OT Security Scanner by SG2 Technologies and Pentity offers a safe, reliable, and effective approach to securing critical infrastructure through passive, real-time monitoring and vulnerability detection.
If your organization operates industrial systems, it’s time to move beyond traditional IT security tools. Let our OT Security Scanner give you the visibility, protection, and peace of mind your operations demand.
