FAQ

Common Questions About OT Security Services

Answers for operational and security teams evaluating OT protection strategies.

How is OT security different from traditional IT security?
+
OT security focuses on industrial safety, uptime, and operational integrity — where downtime or misconfiguration can cause physical damage or safety hazards. IT security primarily protects data and business systems. OT environments also use specialized protocols like Modbus, DNP3, and OPC, requiring purpose-built security tools.
Can you secure legacy industrial systems?
+
Yes. We design hybrid security solutions specifically to protect older OT equipment — including systems that cannot be patched or updated — without impacting performance or production schedules. This includes passive monitoring, network segmentation, and compensating controls.
Do you offer OT security monitoring services?
+
Yes. Our OT SOC team provides continuous monitoring, behavioural anomaly detection, threat triage, and rapid incident response — all tuned specifically for industrial and operational technology environments.
What compliance standards do you support?
+
We provide compliance readiness support for IEC 62443, NERC CIP, ISO 27019, and other sector-specific frameworks. Our services include gap analysis, risk mapping, control implementation, and audit-ready evidence documentation.
How do you detect threats without disrupting production?
+
We use passive network monitoring and out-of-band traffic analysis. This allows us to identify anomalies and threats in real-time without sending active probes that could crash sensitive PLCs or legacy controllers.
Do you help with IT/OT convergence security?
+
Yes. We focus on securing the demilitarized zone (DMZ) between corporate IT and the factory floor, implementing strict access controls and protocol filtering to prevent lateral movement of threats.
Can you secure remote OT sites or pipelines?
+
We implement ruggedized secure gateways and encrypted remote access solutions specifically designed for remote industrial environments, ensuring safe connectivity for field engineers and automated systems.
What is your approach to vulnerability management in OT?
+
Since industrial systems often cannot be rebooted or patched immediately, we focus on virtual patching and network-level segmentation to mitigate risks until a scheduled maintenance window is available.
