Operational Technology (OT) Security
Assess industrial control systems, SCADA networks, PLCs, and HMIs using safety-first methodologies that protect operational uptime while identifying security risks.
Overview
OT security focuses on protecting Industrial Control Systems (ICS) — including SCADA systems, PLCs and HMIs — where safety, reliability and operational uptime are the primary priorities. OT security testing assesses industrial control systems such as SCADA, PLCs, DCS and HMIs, where safety and availability outrank confidentiality. Using safety-first, largely passive techniques, we map the OT environment, evaluate IT/OT segmentation and identify vulnerabilities that could disrupt physical processes.
Methodology & Standards
ISA/IEC 62443 (Security Levels SL 1-4), NIST SP 800-82 Rev. 3 and NERC CIP for utilities. Active testing only on lab, non-production or maintenance windows. Engagements cover assessment of the OT environment, access-control review, continuous monitoring, and routine testing and validation.

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.
No. Production OT environments are assessed using safety-first methodologies, with active testing limited to approved maintenance windows, lab environments, or non-production systems whenever required.
