AirTrunk builds and operates hyperscale data centres across Asia-Pacific and the Middle East - megawatt-scale facilities purpose-built for the speed and density demands of major cloud providers. Founded in 2015, the company opened Australia's first and largest hyperscale sites in 2017 and has since grown into the region's largest data centre platform. In 2024, Blackstone acquired the company in a deal valued at A$24 billion, underscoring the infrastructure's critical role in global cloud and AI compute pipelines.
The attack surface is substantial. AirTrunk's footprint spans Australia, Japan, Singapore, Malaysia, Hong Kong, India, and Saudi Arabia (with expansion underway), operating physical and network infrastructure that underpins hyperscale cloud and AI workloads. The threat model for a platform at this tier is multi-layered: securing operational technology across critical power and cooling systems, defending against supply-chain compromise in a capital-intensive buildout, managing cross-jurisdictional data sovereignty requirements, and maintaining availability against DDoS and ransomware campaigns targeting critical infrastructure.
Security teams here operate in a domain where physical and cyber converge - SCADA and BMS environments sit alongside cloud-scale network architecture. The technical scope covers hyperscale data centre design, cloud infrastructure, and AI infrastructure, which means the tooling and domains you'll touch extend from OT security and network segmentation to identity governance across multiple regulatory regimes. If you're looking for a role where the stakes are measured in megawatts and uptime SLAs backed by hyperscale customers, this is the operational context.
