Learn moreOTONUS delivers end-to-end cybersecurity programs across IT and OT environments, aligning IEC 62443, NIST CSF, and ACSC Essential Eight to the specific risk profiles of operational technology. We bridge the gap between corporate IT security and safety-critical OT networks — protecting availability, integrity, and safe operation.
OTONUS provides independent and embedded functional safety engineering across the full SIS lifecycle — from hazard identification and SIL determination through to design, verification, and operational validation. Our approach integrates seamlessly with process safety management and assurance frameworks.
OTONUS engineers operational resilience for high-availability assets by combining resilience metrics, barrier-based thinking, reliability engineering, and abnormal situation management. We apply scenario stress-testing, weak-signal detection, and data-driven leading indicators to reduce exposure to cascading events and latent conditions.
OTONUS integrates IIoT, edge–cloud architectures, digital twins, and advanced analytics with rigorous safety, cyber, and governance controls. We build human-centred, explainable, and resilient digital operations — where operators and engineers collaborate with decision-support systems that are transparent, auditable, and safety-aligned.
OTONUS modernises alarm systems to reduce nuisance alarms, prevent alarm floods, and improve response quality during abnormal situations. Our methodology aligns to EEMUA 191 / ISA-18.2 while embedding industrial human factors engineering to address operator workload, attention, cognition, and interface clarity.
OTONUS delivers full-lifecycle design engineering and SCADA software development for complex industrial control environments. We combine rigorous systems design with deep OT domain expertise to produce control architectures, HMI solutions, and SCADA applications that meet safety, performance, and maintainability requirements.
OTONUS provides defensible system assurance for complex, integrated assets — linking requirements, hazards, controls, verification, and operational evidence into a single traceable assurance narrative. Our framework unifies systems engineering, functional safety, operational safety, and OT cybersecurity to manage emergent risk across interfaces, upgrades, and through-life changes.
OTONUS is a specialist industrial and technology consultancy serving high-hazard and capital-intensive industries including oil & gas, mining, energy, utilities, and advanced manufacturing.
Our multidisciplinary teams bring rigorous engineering discipline, deep domain expertise, and a structured methodology to every engagement — from strategy through to execution and ongoing assurance.
We do not separate safety from cyber, or resilience from digital transformation. Our value is in the integration — delivering solutions that hold together under the real conditions your assets face.
Safety, cyber, resilience and digital — unified under a single engineering team and methodology. No handoffs, no gaps.
Our engineers have operated in and alongside the facilities we design and assure. No disconnect between theory and practice.
Deep expertise in IEC 61508, 61511, 62443, ISA-18.2, NIST CSF — applied pragmatically to your risk context, not academically.
Every recommendation is traceable to data, risk context, and operational reality — audit-ready by design, not afterthought.
Human factors, operator interface design, and organisational capability embedded in every technical solution we deliver.
We produce executable roadmaps and tangible artefacts — not reports that sit on a shelf. Outcomes, not outputs.
Whether you have an immediate need or are planning ahead, our team is ready to help you identify the right approach and the right level of engagement.
