Keep critical operations safe, reliable and secure
Industrial control systems run the processes your business, and often your community, depends on. We monitor your operational technology continuously, so you can act before a cyber event becomes an operational or safety incident.
When OT is compromised, the impact is physical
OT networks were built for reliability, often decades ago, with little expectation they would ever be connected. Today they link to corporate IT, remote vendors and the cloud, exposing PLCs, SCADA and safety systems to attacks they were never designed to withstand.
Conventional IT security tools can disrupt sensitive industrial protocols, and patching is rarely simple. Many operators lack a clear picture of what is on their OT network and how it normally behaves.
OT security monitoring is one of the most important capabilities in any cybersecurity portfolio. Cubic Application Trading LLC delivers it as a proactive service that protects the mission-critical systems behind your infrastructure.
Assess, baseline, monitor, improve
Assess
We review your current OT security architecture against recognised frameworks such as IEC 62443 to identify deficits and set priorities.
Baseline
We passively discover assets and learn normal communication patterns, without disrupting live processes.
Monitor
We watch continuously for threats, unauthorised changes and deviations from your expected security posture, with real-time alerts.
Improve
We turn findings into meaningful architectural changes, then keep monitoring to confirm they hold.
OT security monitoring capabilities
Visibility and detection built for industrial environments, where safety and uptime come first.
Passive asset discovery
A complete, continuously updated inventory of OT assets, firmware versions and connections, gathered without active scanning that could disrupt operations.
Industrial threat detection
Protocol-aware monitoring that detects malicious commands, known OT malware and anomalous behaviour across PLCs, HMIs and SCADA systems.
Configuration and integrity monitoring
Alerts when controller logic, configurations or critical files change unexpectedly, whether through an attack or human error.
OT-safe vulnerability assessment
Identification of vulnerable assets using passive and carefully controlled techniques, prioritised by operational impact rather than raw severity scores.
IT/OT boundary visibility
Traffic monitoring and deception at the points where corporate and industrial networks meet, where many OT attacks begin.
Integrated security operations
OT alerts fed into your SOC alongside IT events, giving one view of threats that cross the boundary between the two.
