Cyber Security

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.

Our approach

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.

What we do

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.
