Essential Eight Maturity Assessment & Consulting
Protect what matters with Essential Eight Maturity Assessment & Consulting
The Essential Eight is a set of eight prioritised mitigation strategies published by the Australian Signals Directorate (ASD) to help organisations defend against cyber attacks, measured against a maturity model from Level Zero to Level Three. Aesparrow’s Essential Eight assessment measures your current maturity for each strategy, identifies the gaps to your target level and delivers a practical remediation roadmap.
We assess each strategy with technical evidence rather than questionnaires alone — reviewing patch levels, application control, macro settings, administrative privileges, MFA coverage and backups — and validate key controls with targeted security testing.
