Operational Technology (OT) Security
Operational Technology (OT) Security
Our OT security testing and assessment services identify vulnerabilities across industrial control systems (ICS), SCADA networks, PLCs, DCS and HMIs while using safety-first methodologies designed to protect operational uptime and plant safety.
Overview
Operational Technology (OT) security is the practice of protecting industrial control systems, networks and connected devices that monitor and control physical processes. OT security testing identifies vulnerabilities while prioritizing safety, availability and operational continuity. OT security testing and assessment protects industrial control systems (ICS) such as SCADA, PLCs, distributed control systems (DCS) and HMIs. Unlike conventional IT security testing, OT assessments prioritize safety, availability and operational continuity. Our safety-first approach maps OT assets, reviews IT/OT segmentation and identifies vulnerabilities that could affect industrial processes without unnecessarily disrupting production.
Methodology & Standards
Our OT security assessment methodology aligns with ISA/IEC 62443 Security Levels 1–4, NIST SP 800-82 Rev. 3 and NERC CIP where applicable. Assessments include OT asset discovery, network architecture review, IT/OT segmentation analysis, access-control review, passive network analysis and safety-aware vulnerability assessment. Active testing is restricted to approved lab, non-production or maintenance-window environments.

Frequently Asked Questions
No. We default to passive monitoring and architecture review on production OT. Any active testing happens on lab or non-production systems, or during scheduled maintenance windows.
In OT an outage can stop production or create a safety hazard, so risk is measured in operational and safety consequences. Standard IT scanning can crash legacy PLCs, so we use OT-specific, non-disruptive methods.
An OT security assessment includes OT asset inventory and network mapping, zone-and-conduit and network segmentation analysis, passive OT network security analysis, risk assessment against ISA/IEC 62443 Security Levels, IT/OT segmentation security review, OT vulnerability assessment, and prioritized remediation guidance. Active testing is restricted to approved lab, non-production or maintenance-window environments.
