Networks, infrastructure and security for connected production. We bring OT, IT and cloud together around safety, quality and the way your plant operates.
Supporting autonomous operations, convergence and connected services.
We engineer the networks, infrastructure and integrations that let plant systems work with business applications and cloud services. The design accounts for latency, availability, data quality and what happens when a connection fails.
Plant to cloudControlled connections. Defined dependencies.
Production
Keep control close to the process.
Machines, sensors and operators
Time-critical control and safety requirements set the boundaries.
Site & edge
Connect with a purpose.
Industrial networks, compute and data exchange
Approved flows, segmentation and visibility across OT and IT.
Connected services
Put operational data to work.
Business systems, cloud and service providers
Quality, maintenance, planning and support for autonomous operations.
We define which services depend on connectivity, how local operation continues and when people need to intervene.
What Quokka brings
Engineering across the whole plant.
From cabinets, power and cabling to wired and wireless networks, routing, security and cloud integration. We carry the architecture through construction, brownfields migration, testing and operating handover.
01
Safety and quality shape the design.
We work with plant engineering and operations to understand the consequence of a lost connection, incorrect data or an unavailable service. Those requirements shape network behaviour, failure containment, change windows and acceptance checks.
02
Protect the equipment you need to keep.
Where a device cannot be patched or support a required control, we design compensating controls around it: restricted network paths, mediated support access and monitoring. We test their effectiveness and document the remaining risk for the accountable owner.
03
Make Industry 4.0 and 5.0 operable.
Connected machines and services need dependable infrastructure. We design for integration and automation alongside people, resilience and resource efficiency, with clear operating limits, recovery behaviour and intervention points as autonomy increases.
Control the connections. Plan for change and recovery.
We design and test the boundaries, support paths and recovery steps around the equipment you operate.

Named support identity
Approve the engineer, support task and session duration.
Controlled access point
Approve and record the connection across the site boundary.
Authorised engineering PC
Limit the work to the agreed workstation and production cell.
Other OT cells stay separate
Access to other controllers and HMIs needs separate permission.
Keep engineering access within the agreed OT boundary.
Connect the named engineer to the authorised engineering workstation through controlled access. Agree the support task, emergency arrangements and session end with the operating team.

Corporate IT
Business services request only the required production information.
Industrial DMZ
Mediate approved data exchange across the boundary.
Control zone
Keep operator HMIs and controllers within their defined operating zone.
Direct path denied
Test required flows and confirm that bypass routes are blocked.
Give each permitted connection a purpose.
Separate production, site services and corporate systems. Test required paths and verify that unnecessary paths are denied.

Agree the change window
Operations and engineering agree scope, stop conditions and authority.
Apply the approved change
Keep the work within the agreed production boundary.
Check operating behaviour
Use the plant acceptance checks before resuming normal operation.
Pass: resume. Fail: stop or recover.
The authorised owner decides the next step using the agreed recovery plan.
Plan the way back with the operating team.
Agree change limits, rollback steps and who can make the recovery decision. Validate the plan against the actual plant and operating constraints.
