OT Vulnerability Assessment
Identify security weaknesses across your industrial control systems without disrupting operations.
Service Overview
Our OT Vulnerability Assessment service identifies security weaknesses across your industrial control systems environment using a combination of passive monitoring, active scanning (where safe), and manual analysis.
We understand that OT environments demand a different approach than IT—our assessments are designed to identify vulnerabilities without causing operational disruptions. Our team has extensive experience with SCADA systems, DCS platforms, PLCs, RTUs, and industrial network protocols across multiple vendors including Siemens, Rockwell, Schneider Electric, ABB, Emerson, and Honeywell.
Key Benefits
Comprehensive Coverage
Complete vulnerability inventory across IT/OT boundary, control systems, field devices, network infrastructure, and industrial protocols.
Safe Methodology
Assessment methodology designed for operational environments with passive monitoring and coordinated safe testing approaches.
Risk-Based Prioritization
Vulnerabilities prioritized based on exploitability, operational impact, and business criticality—not just CVSS scores.
Legacy System Assessment
Identification of legacy system risks and practical compensating controls when patching is not feasible.
Threat Intelligence
Integration with vendor advisories, ICS-CERT alerts, and threat intelligence to identify actively exploited vulnerabilities.
Remediation Guidance
Practical remediation recommendations including patches, configuration changes, segmentation, and compensating controls.
Assessment Scope
Control Systems
SCADA servers, HMIs, engineering workstations, historians, OPC servers, application servers, and operator consoles.
Field Devices
PLCs, RTUs, IEDs, safety controllers, VFDs, meters, sensors, and field instrumentation.
Network Infrastructure
Industrial switches, firewalls, routers, wireless access points, serial converters, and network appliances.
Industrial Protocols
Modbus TCP/RTU, DNP3, IEC 61850, OPC UA/DA, EtherNet/IP, PROFINET, BACnet, and proprietary protocols.
Remote Access
VPN gateways, jump servers, remote desktop services, vendor access solutions, and third-party connections.
IT/OT Boundary
DMZ firewalls, data diodes, proxy servers, historian interfaces, and IT/OT integration points.
Frequently Asked Questions
Will scanning disrupt our operations?
Our methodology uses passive monitoring as the primary technique. Active scanning is coordinated, uses safe settings, and can be scheduled during maintenance windows if needed.
Can you assess systems from multiple vendors?
Yes. Our team has experience with major vendors including Siemens, Rockwell, Schneider, ABB, Emerson, Honeywell, GE, Yokogawa, and others.
How do you handle legacy systems that can't be patched?
We provide compensating control recommendations including network segmentation, access controls, and monitoring to reduce risk when patching is not feasible.
