Industrial & OT

Secure and modernise OT networks with resilient segmentation, threat protection, and visibility across SCADA, ICS, and automation systems, without disrupting operations. SOCI Act-aware for critical infrastructure operators.

IT/OT segmentation, ISA/IEC 62443-aligned network engineering, and SOCI Act readiness for Victorian manufacturers, utilities, and critical infrastructure operators – delivered without shutting down production lines during design or implementation.

SECTOR CHALLENGES WE ADDRESS
Legacy systems that can't be patched
OT environments run PLCs, HMIs, and industrial controllers with support lifecycles measured in decades, not years. Windows XP-era systems still run production. Modern security has to work around, not through, those constraints.
Uptime versus security patching
Production downtime for a patch cycle costs real money, and many OT systems require vendor certification for changes. Security has to fit inside planned outages or be delivered via compensating controls between them.
Vendor and engineer remote access
OEMs, integrators, and internal engineers all need remote access to OT systems. Traditional IT VPN patterns don't fit – the risk profile of a compromised vendor session into a PLC is different, and requires purpose-built architecture.
SOCI Act positive security obligations
The Security of Critical Infrastructure Act imposes real obligations on critical infrastructure operators – including mandatory reporting timelines that don't tolerate incident response fumbling. Preparation matters.
IT and OT organisational silos
IT and OT teams historically don't share tooling, terminology, or reporting lines. Modern cybersecurity requires cooperation. We work across both silos rather than picking sides.
HOW WE DELIVER
IT/OT Segmentation
Purdue-model aligned network segmentation between corporate IT, DMZ, and OT zones – including managed data flows, industrial firewalls, and unidirectional gateways where the risk profile demands it.
SCADA & ICS Visibility
Passive network monitoring of OT environments – asset inventory, protocol-aware detection, and anomaly alerting without introducing risk to production systems that don't tolerate active scanning.
ISA/IEC 62443 Alignment
Security zone and conduit design, security level target-setting, and control implementation aligned to ISA/IEC 62443-3-3 requirements. Practical implementation, not documentation theatre.
SOCI Act Support
For critical infrastructure operators – positive security obligation program design, mandatory reporting readiness, cyber security incident response, and Enhanced Cyber Security Obligations preparation where applicable.
Secure Remote Access for OT
Vendor and engineer remote access to OT systems – jump host architectures, session recording, just-in-time access, and MFA enforced without breaking the operational realities of shift-based support.
OT-Safe Patch Management
Patching strategies that respect production windows, HMI and PLC constraints, and vendor certification cycles – plus compensating controls for legacy systems that can't be patched at all.
Redundant Industrial Networks
REP, DLR, PRP, and HSR topology design for high-availability industrial networks – with the deterministic failover behaviour production systems require.
OT Incident Response
Runbooks that account for the difference between IT and OT incident response – safety first, production continuity second, forensic preservation without shutting down critical processes.
FREQUENTLY ASKED QUESTIONS

What industrial & ot organisations ask about cybersecurity and IT.

Does the SOCI Act apply to us?

The Security of Critical Infrastructure Act 2018 (amended 2022) applies to entities operating critical infrastructure assets across 11 sectors – energy, water, transport, communications, financial services, and others. Positive security obligations include a risk management program, mandatory cyber security incident reporting, and – for the highest-risk assets – Enhanced Cyber Security Obligations. Whether you're captured depends on the specific asset and sector rules. We can help you work out whether you're in scope.

How do you assess an OT network without breaking it?

Passive first. Active scanning of OT networks can crash PLCs and HMIs that don't handle unexpected traffic well – we've seen it happen. Passive network monitoring (via SPAN ports or network TAPs) gives us asset inventory, protocol visibility, and anomaly detection without touching the control systems. Active testing happens only in scheduled outage windows with vendor and safety sign-off.

What does ISA/IEC 62443 alignment actually deliver?

ISA/IEC 62443 is the international standard for industrial cybersecurity – zones and conduits, security levels, and requirements across system, component, and service dimensions. Practical outcomes: a defensible network segmentation design, documented data flows across security levels, and controls that map to the risk of the specific process being protected. It's a framework for structured decision-making, not a checklist of products.

How do you handle remote access for OEMs and integrators?

Purpose-built OT remote access architecture – jump hosts inside the IT/OT DMZ, session recording, MFA, just-in-time access granted per engagement (not permanent), and time-bounded per session. Direct VPN into an OT network is not acceptable in 2026. Vendors that push back on modern remote access are a red flag worth investigating.
