Where do you start?
Most organisations already track the eight strategies in ASD’s current maturity model. We assess where you stand against it today and use that as your transition baseline, so the work you have already done keeps counting. The model rates each strategy separately, from Maturity Level Zero (not yet meeting Level One) to Maturity Level Three, and assessors follow ASD’s assessment process guide to evidence each level. This work sits alongside our wider cyber security services.
How is ASD Essentials structured?
ASD Essentials is built from four parts:
- Principles: the cyber security outcomes your organisation should achieve.
- Actions: what needs to be done to achieve each outcome.
- Domains: logical groupings of business functions and assets that share similar risks. There are six technical domains and two capability domains.
- Priority phases: the recommended order for addressing the domains. They replace the maturity levels of the current model.
An asset can sit in more than one domain. In that case, you apply the actions from the earliest priority phase first and add later actions as you progress.
The series has separate chapters for enterprise IT, cloud and operational technology (OT). The core concepts apply to every chapter, but the specific principles, actions and priority phases differ, so scope each environment against its own chapter. ASD consulted on the framework from 15 June to 12 July 2026 and made changes in response, including clearer terminology, more scoping guidance and guidance on AI, before launching it on 15 October 2026.
What do the effectiveness ratings mean?
Each action is rated for the assets in scope:
- Not effective: the action is absent, or doesn’t achieve its intended outcome.
- Partially effective: the action achieves its outcome in part, with gaps in coverage, consistency or enforcement.
- Fully effective: the action demonstrably achieves its outcome across the domain, backed by sufficient evidence.
- Not assessed: the action hasn’t been assessed yet.
How do today’s controls carry forward?
In most cases, ASD says, controls you already run under the current model directly satisfy, or substantially contribute to, an action in ASD Essentials. The framework table on this page shows where common controls land. What changes is how progress is measured:
| Topic | Current maturity model | ASD Essentials |
|---|
| Approach | Eight prescribed strategies | Principles and actions |
| Progress measure | Maturity Levels Zero to Three | Priority phases |
| Rating | Maturity level per strategy | Not, partially or fully effective per action |
| Scope | Mainly Windows-based networks | Enterprise IT, cloud and OT chapters |
What does the AI accountability principle mean in practice?
If your staff use Microsoft 365 Copilot, ChatGPT or other AI tools, this principle gives leadership a clear reason to put policy, data controls and oversight in place. Our AI security and governance service helps you do that.
How does it fit with your other programs?
ASD Essentials is compatible with ASD’s Information Security Manual (ISM), and ASD’s assessment evidence guide lists controls from other frameworks that may serve as evidence, including ISO/IEC 27001 and NIST. If you run an ISO 27001 information security management system, we line up the two programs so the same evidence serves both.
Once the baseline is in place, ongoing work such as patch tracking often moves into vulnerability management or managed security, which helps progress hold between reviews.
