Secure OT & Critical Infrastructure
We specialise in securing operational technology and critical infrastructure environments, and secure the systems that keep your world running - protecting OT, ICS, and critical infrastructure with resilient architectures, strong controls, and continuous threat visibility.
Our specialists ensure safe, uninterrupted operations across your most mission-critical environments through secure network design, asset discovery, segmentation, threat detection, and compliance uplift aligned to frameworks like ISA/IEC 62443 and SOCI.
We help operators safeguard industrial processes, reduce cyberphysical risk, and build resilient, highavailability environments that keep essential services running safely and without interruption.

Capability Uplift
Engineering resilience for the systems that keep your world running.
OT Asset Visibility & Governance
Build a living, audit ready inventory of OT/ICS assets, comms paths and criticality - so you can control, monitor and recover with confidence.
Secure Architecture & Segmentation
Design defensible networks with layered zones, DMZs and microsegmentation to contain threats and minimise blast radius across plants and field sites.
OTAware Threat Detection & Monitoring
Deploy passive, protocolaware monitoring and SOC workflows that surface anomalies early and turn alerts into rapid, actionable response.
Secure Remote Access & Identity for OT
Lock down vendor and operator access with hardened gateways, MFA (including for service accounts), justintime privileges and session recording - without disrupting operations.
Vulnerability, Patch & Configuration Management (OT)
Treat ICS vulnerabilities safely with riskbased patching, virtual patching, golden configs and strict change control tailored to industrial realities.
Cross Domain Security and IT/OT isolation
Robust crossdomain architectures that enforce strict separation between IT and OT, using controlled pathways, datadiodes, and airgap strategies to protect industrial systems. from enterpriseside threats.
Cybersecurity Tabletop Exercises
Bespoke, scenario‑driven cybersecurity tabletop exercises that replicate realistic cyber incidents to rigorously test organisational readiness, validate response plans, uncover gaps, and strengthen resilience across technical, operational, and executive team.
Skill and Capability Development
Develop client teams with practical, applied training that strengthens data protection, cyber defence, and OT security capability to ensure your organisation can confidently operate, protect, and respond. protection, cyberdefence, and OT security capability.
Assurance
Independent assurance services that align organisations to leading security and risk frameworks, validate the strength of controls and mitigations, and ensure governance, risk, and compliance practices are robust, defensible, and ready for scrutiny.
Compliance & Meeting Your Standards
ISA/IEC 62443 - Securing Operational Technology (OT)
We help organisations adopt and implement ISA/IEC 62443 to uplift OT security maturity, validating system architecture, hardening controls, and ensuring industrial environments are protected, compliant, and resilient against modern threats.
Cognitio Digital delivers ISA/IEC 62443 aligned assessments, system architecture reviews, and control validation to secure industrial environments, strengthen risk treatments, and ensure OT systems operate within globally recognised security standards.
Essential Eight
Cognitio Digital helps you implement the Australian Government’s Essential Eight baseline to make it significantly harder for adversaries to compromise your systems, with practical, prioritised controls that prevent, limit impact, and speed recovery.
Our qualified Essential Eight assessors deliver independent assessments, handson remediation, and targeted uplift programs that are vendorneutral, outcomedriven, and tailored to your environment.
From gap analysis to operationalisation, we get you from intent to evidence, and from evidence to resilience.
ISO27001:2022 - Creating certainty in an uncertain threat landscape.
We help organisations build, certify, and sustain Information Security Management Systems (ISMS) aligned to the latest ISO 27001:2022 standard.
We deliver practical gap assessments, security context analysis, and clear remediation roadmaps that strengthen governance, manage risk, and ensure systems, people and processes meet modern security expectations. Whether uplifting toward certification or validating an existing ISMS, our team brings deep experience across ISO27001:2022 Gap Assessments, security program reviews, and compliance readiness, ensuring your organisation is audit‑ready, resilient, and aligned with global best practice.
A regulatory framework that mandates risk management, incident reporting, and security uplift for Australia’s critical infrastructure - ensuring essential services are protected from cyber, physical, personnel and supply‑chain threats.
