Are you confident your small or medium business can recover swiftly from a cyber incident?
In Australia, 58% of SMBs reported cyber attacks in 2024, with average breach costs exceeding AUD 3 million. Increasingly stringent Privacy Act 1988 breach notification rules and the ACSC’s Essential Eight mitigation strategies underline the need for structured resilience. Cyber resilience frameworks guide organisations through preparation, protection, detection, response, and recovery, ensuring minimal disruption and rapid return to normal operations.
This in-depth guide explains why resilience matters, dissects core framework components, and walks Australian SMBs through implementation, measurement, and continuous improvement. Harnessing these frameworks safeguards your revenue, reputation, and competitive edge in an ever-evolving threat environment.
