Unidentified OT assets
The true attack surface cannot be measured without a current inventory of PLCs, HMIs, drives, servers and engineering workstations.

OT Cybersecurity
Make OT assets visible, segment access and keep production secure.
Our OT cybersecurity solution combines passive asset discovery, risk analysis, zone–conduit segmentation, secure remote access, continuous monitoring and incident response with production continuity.
Explore the solution
Disconnecting production from the internet is not enough. Make assets visible, access controlled and network activity traceable.
Flat networks and lateral movement
Unsegmented cells allow a single incident to spread into critical production areas and across plant zones.
Uncontrolled remote access
Supplier and maintenance connections create a persistent attack surface without identity verification, approval, time limits, authorisation and session recording.
/ DEFENCE IN DEPTHNot a single security product,
Not a single security product,
but complementary layers.
OT security combines asset discovery, zone–conduit segmentation, secure remote access, threat monitoring and incident response within one operating model.

- Passive discoveryDevices, protocols and communication relationships become visible without disrupting production traffic.
- Least privilegeUsers, devices and services access only the systems required for their roles.
- Production contextAlarms and anomalies are evaluated by process impact, asset criticality and operational priority.
Access progresses,
and is revalidated at every boundary.
Rather than passing directly from the enterprise network to a field cell, traffic moves layer by layer through controlled conduits. Unauthorised flows are blocked at the boundary and approved sessions are recorded.

/ ENGINEERING SCOPETechnology, process and people
Technology, process and people
within one defence model.
Controls are translated into a practical roadmap that reflects the plant architecture and maintenance realities.
Asset and communication inventory
OT devices, software versions, protocols and inter-system traffic are mapped using passive methods.
Criticality and risk analysis
Asset importance, process impact, exposure and existing controls are assessed together.
Zone–conduit segmentation
Functional cells are separated by boundaries that permit only required services and flows.
Secure remote access
Maintenance access is controlled through multifactor authentication, approval, time-limited authorisation and session recording.
OT anomaly visibility
New devices, unexpected commands, out-of-policy traffic and behavioural changes are monitored.
Response and recovery
OT incident scenarios, backup, recovery and responsibilities are validated through tabletop and field exercises.
Learn normal behaviour,
and see deviations in their production context.
The OT network is monitored passively, comparing device relationships, protocols and critical changes over time so teams can act on contextualised incidents rather than raw alerts.

From the current state to sustainable protection,
in six controlled steps.
- 01Define scope and criticality
Production areas, critical processes, owners and acceptable downtime limits are defined.
- 02Discover assets and traffic
Devices, protocols, connections and existing security controls are made visible.
- 03Prioritise risk
Technical findings are combined with process impact to create a practical remediation sequence.
- 04Strengthen the architecture
Segmentation, secure access, hardening and backup controls are implemented.
- 05Monitor and respond
Anomaly rules, escalation paths and OT-specific incident response procedures are operated.
- 06Validate and improve
Controls are reviewed regularly through exercises and change records.
Risk-based security
at every production layer.
Manufacturing plants
