Technology is now a mission critical part of every organisation. And with the stakes getting higher every year, we’re going further and further to ensure our customers have full confidence in us, and in our delivery across every area of operation.”
Brennan has always been a values-driven company – with all our values focussed squarely on delivering true performance for our customers and their users.
We have made a deep, systemised, and customer-connected commitment to:
Brennan’s early years in emergency system recovery means we understand the true cost of system outages, failures and breaches better than anyone. Which is why we’ve systematically invested in a multi-layered set of security protocols and protections with ISO27001 certification as a start rather than end standard.
Our ‘secure always’ culture has earned Brennan the trust of large scale, complex businesses across prevention, detection, and unlike most, rectification.
To deliver true performance, you work with the best. Brennan has carefully curated a network of partners that help us deliver the ideal mix of quality, options and value.

Brennan (formerly known as Brennan IT) is an Australian systems integrator and managed services provider founded in Sydney, Australia in 1997. We design, procure, implement and manage technology ecosystems for organisations across Australia. With Australian-based operations supported by a global team, our customers benefit from consistent delivery and ongoing improvements, not just “point-in-time” projects.
Brennan believes that how technology is delivered is every bit as important as what the technology is.
It’s a belief backed by Brennan’s True Performance System – a powerful synthesis of meaningful customer surveys, methodical analysis, purpose-built software, and earned expertise accumulated by skilled practitioners, all feeding and shaping a continual program of improvements.
More than a framework, our system represents real, hard-won intellectual property, software, and processes that Brennan have meticulously developed over nearly 30 years from thousands of data points and customer interactions.
Our comprehensive approach ensures that we get closer to our customers and deliver smarter to enhance their actual experience of technology.
Brennan supports more than 1,700 business, enterprise and government customers from offices across Australia (QLD, NSW, ACT, VIC, TAS, SA, WA) plus a Global Service Centre footprint in India and Sri Lanka – a scale designed to support complex, multi-site organisations while maintaining local engagement.
Our values are built around five “True” pillars: Performance, Connection, Security, Delivery and Commitment. In practice, that means being accountable for outcomes, owning issues end-to-end, reducing complexity wherever we find it, and prioritising customer interests over vendor agendas, ensuring our service decisions align to your environment, risk profile and business goals.
Brennan is ISO 27001 certified, which means we maintain a structured information security management system. We treat certification as a baseline, layering additional controls and customer-specific protocols across prevention, detection and rectification.
Our Canberra team all hold AGSVA security clearances, have successfully delivered hundreds of complex projects into 50+ federal agencies, and have extensive experience delivering outcomes in accordance with Government security frameworks including PSPF, Essential 8 and ISM.
