The Essential Eight is a set of eight Cybersecurity mitigation strategies developed by the Australian Signals Directorate (ASD) to help organisations protect themselves against the most common cyber threats.
It's a prioritised, evidence-based framework, built on analysis of real-world attacks, telling you where to focus your defences first.
Prevent unauthorised software from running
Fix known vulnerabilities before they're exploited
Restrict macros to trusted sources
Reduce the attack surface in browsers and common tools
Limit who can make system-level changes
Keep operating systems current and secure
Require more than a password to gain access
Maintain clean copies of critical data to recover from attack
In isolation, each strategy targets a different entry point or escalation method. Together, they address the majority of techniques used in opportunistic attacks and targeted intrusions.
The Essential Eight uses a maturity model with four levels (Maturity Level Zero through to Maturity Level Three). Higher maturity means stronger, more consistent implementation. Most Australian government entities are required to reach at least Maturity Level Two. For businesses outside government, the framework provides a credible, externally validated benchmark for measuring and improving security posture.
Cyber threats aren't slowing down. Regulators, insurers, and customers are increasingly asking organisations to demonstrate that they're taking security seriously. The Essential Eight gives you a structured, credible way to do that.
An experienced MSP will assess your current maturity level, identify the gaps, and work systematically through remediation, prioritising actions that reduce the most risk, fastest.
