Insights

Public Sector Growth Brennan is actively expanding into public sector and utilities, evidenced by TasPorts' digital upgrade and the Rural Water Futures program with the Queensland Government. This signals opportunities for government and critical infrastructure modernization projects. For sales teams, position Brennan as a single provider for end-to-end IT modernization, procurement, and security to win multi-year government contracts.

Security Leadership The Securonix SIEM partnership and CBRCYBER acquisition strengthen Brennan's integrated security and cyber defense capabilities. This enables cross-selling of managed infrastructure, systems integration, and security services to large enterprises seeking unified protection. Target sectors with high regulatory requirements such as government, utilities, and financial services.

Backed Growth A minority stake by Macquarie Capital and ongoing acquisitions signal a growth-focused, well-backed business environment. This can reassure customers about long-term support and enable pursuit of larger multi-year outsourcing deals. Leverage credibility to engage with mid-market and enterprise buyers needing scale and continuity.

Integrated Modernization Brennan's True Performance System and broad tech stack enable tailored IT modernization programs across commerce, cloud, automation, and security. This positions the company well for clients seeking consolidation under a single provider for design, procurement, implementation, and ongoing management.

Regional Growth Recent client wins and partnerships across ANZ demonstrate Brennan's ability to scale and serve diverse industries with a regional footprint. Growth opportunities include expanding in ports, utility customers, education and health sectors, and building partner ecosystems for co-delivery and accelerated go-to-market.
