Essential Eight Compliance & Maturity Assessment

Nano Solutions assesses your Essential Eight maturity across all eight mitigation strategies, shows you exactly where you stand, builds a costed roadmap to your target level, and does the remediation — patching, application control, multi-factor authentication, hardening and backups. Established 2013, WA Government CUAICTS2021 panel supplier (Contractor #225). Assessment to compliant, with one team.

The ACSC Essential Eight is the baseline for Australian government and a fast-becoming standard for everyone who works with them. We don't just hand you a report — the same team that scores your maturity does the uplift work to close the gaps.

Who it's for

Essential Eight compliance matters most to:

• Government suppliers — organisations bidding for or holding WA and federal government contracts where an Essential Eight baseline is expected.
• WA mining & resources — operators and service providers protecting operational technology and corporate systems.
• Community-services organisations handling sensitive personal data.
• Any business that needs to prove its security baseline to win or keep contracts.

What is the Essential Eight?

The Essential Eight is ASD's baseline set of eight mitigation strategies for internet-connected corporate IT: patch applications, patch operating systems, multi-factor authentication, restrict administrative privileges, application control, restrict Microsoft Office macros, user application hardening, and regular backups. Maturity is scored per strategy from Level Zero to Level Three — and your overall level is your weakest strategy, not your average.

The full reference lives in our Essential Eight knowledge hub, where it stays current and sourced: a complete requirements matrix covering every strategy at every maturity level with the real patching timeframes, a page per strategy, and a tracker for where the framework is heading. This page is about the engagement: what we assess, what we fix, and what it costs.

One thing worth stating plainly, because it gets sold anyway: there is no such thing as Essential Eight certification. ASD's maturity model states there is no requirement for organisations to have their implementation certified by an independent party, and ASD does not endorse or register Essential Eight assessors. An independent assessment may still be required of you by a contract, a regulator or a government directive — that is a procurement obligation, not a certificate, and we will not pretend otherwise.

You can target a different maturity level per strategy. We help you set the right target based on your risk and obligations, then build a remediation roadmap with effort and risk reduction quantified.

Is the Essential Eight mandatory for my organisation?

It depends on who you are and who you work with:

• Non-corporate Commonwealth entities are directed to implement the Essential Eight — for them it is mandatory.
• WA Government agencies and their suppliers are increasingly required to demonstrate a defined maturity level, often Maturity Level Two, as a condition of contracts under arrangements such as the CUAICTS2021 ICT panel.
• Mining, resources and critical-infrastructure operators may fall under the Security of Critical Infrastructure (SOCI) Act, where the Essential Eight is a practical way to meet risk-management obligations.
• Everyone else — the Essential Eight is not law for private business generally, but it is the clearest, cheapest way to prove a security baseline to insurers, partners and prospects, and to reduce the risk that ends most small-business breaches.

If you are unsure which applies, that is exactly what the assessment answers: where you stand today, what level you actually need, and how to get there. Read our explainer on where the framework is heading for the wider context.

How we work

1. Assessment (1–2 weeks, fixed) — evidence review and interviews produce a maturity scorecard across all eight strategies, plus a target-level gap analysis.
2. Roadmap — a prioritised, costed uplift plan to your target maturity level, sequenced by risk reduction.
3. Uplift (we do it) — patching, MFA rollout, application control, server hardening and a tested backup regime. We use automation tools like Ansible to keep systems hardened and consistent.
4. Annual re-assessment retainer — maturity drifts as systems and people change; we keep you compliant and re-score on a cadence.

Where the Essential Eight is heading

On 15 October 2026 ASD published ASD Essentials, with chapters for enterprise IT, operational technology and cloud. ASD's FAQ describes it as replacing the Essential Eight. Maturity levels give way to priority phases, each action is rated not effective, partially effective or fully effective per domain, and ASD says Essential Eight maturity ratings "do not automatically translate" into the new ratings.

Worth being precise, because the reporting has not been: ASD has not set a retirement date for the Essential Eight. It says it will advise on transition timing "in due course", and that organisations should keep meeting any obligation that requires Essential Eight implementation or reporting. ASD also says every Essential Eight strategy maps to at least one ASD Essentials principle, and it does not recommend slowing or stopping uplift programs. The foundational controls (patching, MFA, admin restriction, application control and tested backups) carry forward.

If you already hold Essential Eight evidence, we can map it to ASD Essentials for enterprise IT and show where it carries forward and where it needs strengthening. Our dated Essentials transition tracker separates what ASD has published from what has only been reported.
