Information Technology (IT) and Operational Technology (OT) are as critical to modern mining as the metals and minerals you extract and refine. In the era of data-driven decision-making, the synergy between IT and OT underpins competitiveness and success.
With over two decades of deep IT experience, Brennan is uniquely positioned to help you consistently extract cost savings, efficiencies and stability across more operational facets of your organisation.
With solutions spanning on-premise, cloud, and hybrid cloud to support the migration and management of your infrastructure, our full-spectrum solutions enable a seamless marriage of your data and control systems to unlock new levels of productivity. These include commonly overlooked fields such as networks, infrastructure, telecommunications, applications, and wider procurement strategies.
Consolidate legacy infrastructure, applications and technology sprawl to enhance efficiency, safety, and profitability. Through enhanced collaboration, we can unlock new ways to optimise resource utilisation, automation systems and control networks.
Working quickly, proactively, and strategically, we can transform your business through modern, innovative outsourced IT solutions that manage and continuously improve your IT environment, freeing your people to focus on their core competencies.
We can help you identify, implement and manage cloud solutions that integrate with your IT and OT environments. We can develop the digital infrastructure and software and systems that support administrative functions, data management, and communication, allowing for optimal resource planning and utlisation, reduced manual labour and productivity gains.
Facilitate quicker, clearer, stable collaboration among geographically dispersed teams, with rock-solid technology and support that enhances real-time data analysis and reporting, enables swift decision-making and reduces downtime for mobile, remote, office-based and FIFO employees.

“It’s important to choose a partner, not just a provider. I absolutely feel that Brennan are an extension of my team.”

When Aurizon, Australia’s largest rail freight operator, decided to make significant end-user support and IT platform support services improvements, Brennan answered the call. Then COVID happened. And the original transition plan needed a quick pivot.

BG&E is a team of more than 850 highly skilled people, in 15 offices across Australia, New Zealand, Singapore, the United Kingdom and Middle East who design and deliver engineering solutions for clients.




By protecting both IT and operational technology (OT) without disrupting production.
Managed IT services support mining resilience by securing hybrid IT–OT environments, maintaining visibility across sites and designing controls that protect safety‑critical systems while enabling continuous operations in remote and harsh conditions.
Remote connectivity failure, inconsistent security controls, limited onsite expertise and poor recovery capability all increase operational risk. These risks are compounded when sites rely on real‑time systems for safety, automation and production continuity.
By clearly separating control systems while maintaining secure visibility. Effective mining environments segment IT and OT networks, tightly control access paths and monitor interactions between systems. This reduces the risk of cyber incidents crossing into safety‑critical operations while still supporting modern automation and analytics.
Managed IT reduces downtime through proactive monitoring, resilient connectivity design and rapid incident response. Rather than reacting to failures, services focus on early detection and recovery planning, a critical difference when minutes of outage can mean lost production or safety exposure.
Connectivity is the backbone of safety, automation and coordination. Reliable networks underpin fleet systems, remote operations and real‑time monitoring. Managed IT ensures connectivity is engineered for redundancy and monitored continuously to prevent single‑point failures across geographically dispersed sites.
Mining environments often involve high contractor turnover and shared systems. Managed IT enforces identity controls, access governance and monitoring so third‑party access does not compromise operational security or safety obligations.
Mining‑grade IT is engineered for extreme availability, safety impact and environmental constraints. It prioritises resilience, simplicity and recoverability over feature depth—recognising that technology failure can stop production or put people at risk.
Brennan works with mining and resources organisations operating across remote, multi‑site and safety‑critical environments. We support resilient connectivity, cyber security and managed IT services that span corporate IT and operational environments, helping mining teams reduce downtime, manage risk and maintain secure operations across the full lifecycle of exploration, production and services.
