What is Operational Technology (OT) Security Assessment?

Operational Technology (OT) Security Assessment is a specialized security evaluation focused on industrial control systems (ICS), SCADA environments, and critical infrastructure networks that manage and monitor physical processes across sectors such as manufacturing, energy, utilities, oil & gas, and transportation. Unlike traditional IT systems, OT environments prioritize availability, safety, and reliability, making security assessments significantly more sensitive. This service provides deep visibility into OT assets, communication paths, and control mechanisms while ensuring that industrial operations remain uninterrupted.

The assessment typically includes:

OT Asset Discovery & Mapping

Identification of PLCs, RTUs, HMIs, sensors, controllers, and industrial network components, including undocumented or legacy assets.

Network Architecture & Segmentation Review

Evaluation of IT–OT separation, firewall rules, DMZ configurations, and lateral movement paths between enterprise IT and industrial networks.

Industrial Protocol Security Analysis

Review of protocols such as Modbus, DNP3, OPC, PROFINET, EtherNet/IP, and others for insecure configurations or unauthenticated access.

Access Control & Privilege Review

Assessment of user roles, remote access mechanisms, engineering workstations, and vendor access pathways.

Configuration & Patch Management Review

Identification of insecure device configurations, outdated firmware, unsupported systems, and unpatched vulnerabilities.

Threat & Risk Evaluation

Identification of attack scenarios that could lead to process manipulation, safety incidents, operational downtime, or equipment damage.

All testing is conducted in a non-intrusive and safety-first manner, avoiding aggressive exploitation or traffic that could disrupt operations. The methodology aligns with CERT-In advisories, NIST guidance, IEC 62443 standards, and industry best practices, ensuring regulatory alignment and operational safety.
The outcome is a risk-prioritized security assessment that helps organizations understand their OT cyber exposure and implement practical, phased remediation without compromising uptime or safety.
