Independent ACSC Essential Eight Maturity Assessment for Australian Organizations

The Essential Eight, published by the Australian Cyber Security Centre, is now the de facto cybersecurity baseline for Australian government suppliers, critical infrastructure operators, APRA-regulated entities and enterprise IT teams. The eight mitigation strategies, application control, patch applications, configure Microsoft Office macro settings, user application hardening, restrict administrative privileges, patch operating systems, multi-factor authentication and regular backups, are scored against three maturity levels (ML1, ML2 and ML3). Government and large enterprise contracts increasingly require evidence of ML2 or ML3 alignment before vendor onboarding.

Codesecure Solutions delivers independent Essential Eight assessment services to Australian organizations from our Chennai cyber practice. Every engagement is delivered under a signed Australian-law NDA, with named consultants, fixed AUD pricing and a board-ready maturity scorecard. Our methodology uses the ACSC Essential Eight Maturity Model and ASD Essential Eight Assessment Process Guide, cross-mapped to ISO 27001, NIST CSF, SOC 2 and where relevant APRA CPS 234 and the Information Security Manual (ISM). We produce evidence that satisfies ACSC, government procurement and enterprise vendor risk teams.

Frequently Asked Questions

The Essential Eight is mandatory for non-corporate Commonwealth entities and is increasingly required for federal and state government suppliers, Defence Industry Security Program members, critical infrastructure operators under SOCI Act, APRA-regulated entities and large enterprise vendor onboarding programs. Many Australian boards now ask for an annual Essential Eight maturity scorecard alongside ISO 27001 certification, regardless of formal regulatory requirement, because it is a clear and well-understood baseline.

ML1 represents protection against adversaries content to use widely available tradecraft against any victim with a vulnerability. ML2 represents protection against adversaries with a modest step-up in capability, willing to invest more time in a target and use tools like password cracking. ML3 represents protection against adversaries adaptive, well-resourced and prepared to invest substantial effort, including using zero-day vulnerabilities and bespoke tradecraft. Most Australian businesses target ML2 as their realistic operating level, with ML3 reserved for highly sensitive environments.

A typical mid-sized Australian organization assessment runs 3 to 5 weeks from kick-off to final scorecard. That includes evidence collection, control testing, scoring against ML1, ML2 and ML3 criteria, the gap register and the remediation roadmap. Larger enterprises with multi-domain AD environments, multiple Microsoft 365 tenancies and complex application portfolios run 6 to 10 weeks. Annual re-assessments run shorter once baseline evidence is in place.

Codesecure publishes transparent AUD price bands. A baseline mid-sized organization assessment runs AUD 8,000 to 18,000 fixed price including the maturity scorecard, gap register, remediation roadmap and walkthrough. Larger enterprises with multi-domain AD, multiple cloud tenancies and complex application estates run AUD 15,000 to 35,000. Annual re-assessments are priced at a discount once baseline evidence is in place.

Yes. After the assessment, Codesecure offers hands-on uplift support including patching strategy, application control deployment, MFA rollout, privileged access uplift, macro hardening, user application hardening and backup verification. Most Australian customers run a 12 to 24 month uplift program with quarterly reviews against the original scorecard, with a formal annual re-assessment to demonstrate progress to the board.
