Essential Eight – The Essential Eight Maturity Model in Action

Achieving cyber security resilience is not a one-size-fits-all journey. The Essential Eight Maturity Model provides a structured roadmap that allows businesses to assess their cyber security posture and implement tailored strategies. Organisations can make measurable progress toward stronger cyber defences by aligning each of the eight mitigation controls to a maturity level.

In this blog, we’ll explore the four maturity levels of the Essential Eight Maturity Model, providing a clear framework for businesses to evaluate their position and chart a path forward.

Understanding the Maturity Levels

The Essential Eight Maturity Model outlines four distinct levels—Level Zero through Level Three. Each level represents an increasing degree of integration and optimisation of the eight mitigation strategies. Organisations can apply these levels individually to each control, making it easier to identify gaps and prioritise improvements.

Level Zero: Initial

At this level, businesses at this level have not implemented the mitigation strategy, or they have only implemented it in a very basic way.

• Example: For Application Whitelisting, a Level Zero organisation may have no whitelisting in place or have implemented it on just a few systems with no ongoing management.

• Key Takeaway: This is the starting point for organisations beginning their cyber security journey.

Level One: Developing

This level reflects partial implementation of a mitigation strategy, but it is not yet consistently applied across the organisation.

• Example: Application Whitelisting may be applied to a majority of systems, but gaps or inconsistencies exist in its coverage.
• Key Takeaway: Level One signifies progress but highlights the need for consistency and broader adoption.

Level Two: Integrated

At Level Two, organisations have fully integrated the mitigation strategy into their operations. Processes are in place to ensure it is consistently applied and maintained.

• Example: Application Whitelisting is implemented across all systems, with a defined process for managing and updating the whitelist as new applications are introduced.
• Key Takeaway: Level Two marks a turning point where strategies begin to deliver tangible benefits.

Level Three: Advanced

Level Three represents the highest maturity, where organisations not only implement and maintain strategies but also optimise and continually improve them.

• Example: For Application Whitelisting, a Level Three organisation uses advanced techniques, such as automation, to manage the whitelist. They also routinely review and refine it to address evolving threats.
• Key Takeaway: At this level, organisations demonstrate a proactive, security-first mindset.

Why Maturity Levels Matter

The maturity model allows businesses to identify and address weaknesses, focus resources effectively, and demonstrate progress to stakeholders. Importantly, it’s not necessary to reach Level Three across all eight controls to achieve a strong cyber security posture. Even partial implementation of the Essential Eight can provide significant protection against common cyber threats.

How to Progress Through the Levels

Each level includes specific activities and outcomes that organisations can use to measure their progress:

1. Assess Current Maturity: Evaluate your organisation’s current standing for each control.
2. Plan for Improvement: Develop a roadmap tailored to your organisation’s needs, focusing on the highest-priority controls.
3. Implement and Optimise: Gradually implement the strategies while building processes for consistency and long-term success.
4. Foster a Security Culture: Cultivate awareness and engagement within your organisation to sustain improvements.

Reaching Level Three maturity requires both technical controls and a strong organisational commitment to cyber security.
