Australian managed services and cloud infrastructure provider for government and enterprises
AC3 is a 201–500-person Australian managed services firm built on ServiceNow, Splunk, Sentinel, and CrowdStrike—the operational backbone of government and enterprise security ops. Their tech mix (AWS, Azure, VMware, Intune, Dynamics 365) signals deep enterprise infrastructure integration rather than product development. Hiring velocity is accelerating with a 4:1 engineering-to-sales ratio, suggesting they're scaling delivery capacity and internal tooling (cost optimization and CMDB accuracy appear repeatedly in their project backlog) rather than chasing new markets.
AC3 provides managed services, cloud migration, and infrastructure consulting across Australian government, healthcare, financial services, and critical infrastructure sectors. Founded in 1999 and privately held, the company operates from five offices spanning Sydney, Melbourne, Brisbane, Auckland, and Wellington. They deliver onshore support across cloud platforms (AWS, Azure), security tools (Sentinel, CrowdStrike), and enterprise software (ServiceNow, Dynamics 365). Current project focus areas include ServiceNow implementations, cost optimization, and multi-provider service integration—indicating both client-delivery work and internal operational scaling.
AC3 operates on ServiceNow, Splunk, Sentinel, CrowdStrike, Power BI, AWS, Azure, VMware, Intune, Azure Entra ID, Dynamics 365, and Terraform for core delivery and operations.
AC3 is headquartered in Haymarket, NSW, with additional offices in Melbourne, Brisbane, Auckland, and Wellington.
AC3's technology stack, projects, and hiring signals are inferred from public hiring and company data — career pages, public listings, and company web presence — then clustered and de-duplicated. Figures are estimates that refresh over time. Read our full methodology →
