Operational Technology Security
OT Network Detection
Industrial environments depend on continuous availability. Digisecuritas helps organisations gain visibility across Operational Technology networks, identify connected assets, detect unusual activity, and strengthen cyber resilience without disrupting critical operations.
Visibility is the foundation of OT security
Many industrial organisations know the assets they actively manage but have limited visibility into every connected device across their Operational Technology environment. As facilities expand and systems become increasingly connected, maintaining an accurate understanding of industrial assets becomes essential for both operational continuity and cybersecurity.
OT network detection provides that visibility by identifying industrial devices, monitoring communications, and highlighting unusual behaviour that may require investigation.
Industrial Asset Visibility
Identify connected operational assets across the OT environment.
Continuous Observation
Monitor communication patterns across industrial networks without interruption.
Protocol Awareness
Understand industrial communication without disrupting operations.
Early Anomaly Detection
Recognise unusual activity before operational impact occurs.
Operational Continuity
Support production while improving cyber resilience.
What we help organisations monitor
Industrial Controllers (PLCs)
PLCs execute automated control logic. Monitoring their communications identifies unauthorised commands and configuration changes.
SCADA Systems
SCADA platforms provide supervisory oversight. Visibility into SCADA traffic supports detection of unusual supervisory activity.
Human Machine Interfaces (HMIs)
HMIs are operator touchpoints. Monitoring HMI access and commands helps identify unusual operator behaviour.
Remote Terminal Units (RTUs)
RTUs collect field data and relay commands. Monitoring RTU communications supports awareness of remote asset activity.
Industrial Switches
Network switches carry all OT traffic. Monitoring switch communications provides a foundation for network-wide visibility.
Engineering Workstations
Engineering workstations configure industrial systems. Monitoring their activity identifies unauthorised configuration changes.
Industrial Servers
Servers supporting OT applications require continuous monitoring to detect unusual access and service behaviour.
Network Segments
Segmentation boundaries define OT zones. Monitoring inter-segment traffic identifies unexpected lateral communication.
Industrial Communication Protocols
OT protocols carry operational commands. Understanding protocol behaviour provides context for anomaly detection.
OT Visibility Framework
Building OT network visibility
Identify industrial assets connected across operational environments.
Passive discovery techniques identify every connected device without querying controllers or interrupting production processes.
Understand relationships between systems, equipment and communication paths.
Asset relationships and communication dependencies are mapped to provide an accurate picture of the operational environment.
Observe network behaviour continuously to identify changes and unusual activity.
Continuous monitoring establishes a communication baseline and detects deviations that may indicate cyber risk or operational anomalies.
Use operational insights to strengthen segmentation, governance and long-term resilience.
Visibility findings inform security improvements, segmentation decisions and a structured roadmap for OT cybersecurity maturity.
Understanding industrial communication
Operational Technology environments rely on specialised communication protocols that differ from traditional enterprise networks. Understanding these communications provides valuable operational context while supporting cyber risk management.
