Zero Trust in the Australian public sector
Public sector cyber breaches used to begin with a complex technical exploit. Today, they are just as likely to start with a valid login. This eBook explores why Zero Trust has become a strategic mandate for Australian government, and how agencies can make the transition in a structured, achievable way.
Developed by Optus and Zscaler in partnership with The Mandarin, this eBook sets out what Zero Trust means in the context of Australian government, the policy frameworks driving its adoption, and how agencies can implement it as a staged, risk-managed transformation rather than a discrete technology deployment.

“Zero Trust is not about buying more tools. It is about interoperability and visibility, enabling faster, better understanding of what is happening across the environment."
Sean Connelly — Senior Director, Global Zero Trust Strategy & Policy, Zscaler. Former Zero Trust Initiative Director, CISA.
"Zero Trust requires organisation-wide architectural change that impacts business operations, risk appetite, and digital transformation, not just security tooling. It requires executive and board-level ownership."
Kavin Arnasalon — Head of Government, Optus Enterprise and Business
