Utilities

Connecting technology to powerful outcomes

Critical to a functioning society and vital to a vibrant economy, utilities are the engines that power every aspect of modern life. Set against a backdrop of critical dependency, resilience, and control, security and service continuity aren’t just aspirations for utility operators. They’re obligations to customers, regulators, and the nation.

Staying ahead in rapidly transitioning, digitised, and demand-heavy environments demands a technology partner that doesn’t just know your systems, but understands your unique pressures spanning security, interoperability, market complexity, demand variability, decentralisation, and more.

At Brennan, we connect technology with real operational outcomes. With a national footprint, nearly three decades of experience, and embedded sector expertise, our strategic thinking, proven know-how, and full-spectrum solutions bridge the worlds of IT and OT seamlessly.

And our True Performance System ensures we work closer, think sharper, and deliver solutions with measurable impact to help you unlock new levels of efficiency, reliability, and security across networks, infrastructure, cloud, control systems, applications, and beyond. Because we’re all about technology that works, not technology you’re sold.

Solutions and support that connect your goals

With local cloud options, onshore support, and standards-aligned frameworks, we help you retain control over your most critical assets, from within Australian jurisdiction.

Protect operational uptime and citizen trust with security solutions tailored to critical infrastructure. From network segmentation to Zero Trust frameworks, Brennan’s cybersecurity approach reduces risk across both IT and OT environments.

We bring the depth, scale, and capability to rival global providers, while remaining agile, responsive, and grounded in local industry understanding. Whether integrating legacy infrastructure or leading a transformation, we’re in Australia, for Australia.

From ISO and SOC2 to the Security of Critical Infrastructure (SOCI) Act, we help you stay ahead of evolving compliance requirements without slowing progress. Our solutions are built to be secure, auditable, and future-fit.

Prevent outages and minimise service disruption with intelligent infrastructure design, proactive monitoring, and reliable support. We build systems that keep running – no matter the load, weather, or geopolitical conditions.
