Confidential Computing: The Next Frontier in Data Privacy for Australian Businesses
Your data is encrypted when it is stored. It is encrypted when it travels across the network. But what about when it is actually being processed? In 2026, that gap is finally being closed — and it changes everything about how businesses can safely use sensitive data in the cloud.
Most businesses understand encryption at rest and encryption in transit. What many do not realise is that data has traditionally been decrypted and exposed in plain text during processing. That moment of exposure is where sophisticated attackers focus their efforts.
Confidential computing solves this by using hardware-level secure enclaves — protected areas of a processor — to keep data encrypted even while it is being actively computed on. Sensitive information can be processed in shared cloud environments without ever being visible to the cloud provider, other tenants, or potential attackers.
Australia’s Privacy Act amendments have raised the stakes for how businesses handle personal data. The notifiable data breaches scheme already requires organisations to report serious breaches — and penalties are increasing. At the same time, more business workloads than ever are moving to shared cloud infrastructure, creating new exposure risks that traditional security models were not designed to address.
