Essential Eight Maturity Levels
The Essential Eight Maturity Model contains four maturity ratings, from Level Zero to Level Three.
An organisation’s overall maturity is generally determined by its lowest-rated strategy. Meeting seven strategies at Maturity Level Two and one at Maturity Level One would ordinarily produce an overall Maturity Level One result. All controls for a strategy must be effective, or supported by an equivalent alternate control, before that strategy can be claimed at the target level.
Maturity Level 0
Maturity Level Zero means the organisation does not meet all requirements of Maturity Level One.
This may indicate gaps such as inconsistent patching, incomplete MFA, users retaining administrator access, inadequate application restrictions or backups that are not appropriately protected.
Level Zero is not a target maturity level. It is used to identify that foundational weaknesses remain.
Maturity Level 1
Maturity Level One is intended to reduce exposure to attackers using common, publicly available tools and techniques.
It establishes a practical technical baseline across patching, application control, Office macros, application hardening, privileged access, MFA and backups.
For many ordinary small businesses without specific contractual requirements, Maturity Level One may be an appropriate initial target.
Maturity Level 2
Maturity Level Two is designed for organisations exposed to more capable attackers who invest greater effort in targeting specific systems and credentials.
It introduces broader technical coverage, stronger application control, more restrictive security configurations, improved logging, stronger MFA requirements and tighter management of privileged access.
Maturity Level Two is a common target for government environments and organisations supplying services into higher-risk or regulated supply chains. Australian Government non-corporate Commonwealth entities are required under the PSPF to implement the Essential Eight to at least Maturity Level Two.
Maturity Level 3
Maturity Level Three is intended for organisations facing highly capable and adaptive attackers.
It requires more mature technical controls, faster remediation, stronger authentication, broader monitoring and greater resistance to attackers attempting to bypass existing protections.
This level is generally most appropriate for organisations handling highly sensitive information, critical systems or significant government and enterprise responsibilities.
We Partner With Industry Leaders
Why Work With Accel IT?
Accel IT combines cybersecurity implementation experience with an understanding of the operational pressures faced by small and medium-sized Australian businesses.
We do not approach the Essential Eight as a generic checklist. Our team reviews how your users, applications, cloud services, endpoints and servers actually operate before recommending a target maturity level or implementation plan.
Because we also provide managed IT services, Microsoft 365 security, endpoint management, Huntress protection, patching, backups and technical support, many Essential Eight controls can be implemented and maintained through a single ongoing service.
This reduces the risk of security configurations being applied during a project and then gradually falling out of compliance as users, devices and applications change.
Our goal is to produce a practical security uplift that protects the business, supports customer requirements and can be maintained after the initial assessment is complete.

Essential Eight FAQs
Is the Essential Eight mandatory for every Australian business?
No. The Essential Eight is strongly recommended cybersecurity guidance, but it is not automatically mandatory for every private Australian business.
It may become mandatory where it is required by government policy, a customer contract, a regulator, a tender or your organisation’s internal security requirements.
Does the ACSC issue an Essential Eight certificate?
No. ASD and the ACSC provide the framework and assessment guidance but do not issue an official Essential Eight certificate.
Which Essential Eight maturity level should we target?
The appropriate level depends on the information you hold, your customers, contractual obligations, likelihood of being targeted and the consequences of a security incident.
Maturity Level One may suit many ordinary businesses as a starting point. Maturity Level Two is generally more appropriate for organisations with government, regulated or higher-risk requirements.
Can we achieve Maturity Level Two without completing Level One?
The maturity levels build on each other.
ASD’s assessment guidance states that an organisation should not begin an assessment against Maturity Level Two without first demonstrating that it has implemented Maturity Level One. The same progression applies from Level Two to Level Three.
Does Microsoft 365 Business Premium achieve Essential Eight compliance?
Microsoft 365 Business Premium provides useful tools for MFA, device management, security policies and application control, but purchasing the licence does not automatically achieve an Essential Eight maturity level.
Does antivirus satisfy application control?
No. Antivirus attempts to identify and block known or suspicious threats.
Application control restricts which programs, installers, scripts and software libraries are permitted to execute. The two controls perform different roles and are often used together.
How long does an Essential Eight project take?
A Maturity Level One project may take approximately two to four months in a relatively modern environment.
Maturity Level Two commonly takes three to nine months, while Maturity Level Three may take considerably longer. Legacy systems, custom software, project approvals and user disruption can all affect the timeframe.
Can Accel IT maintain the controls after implementation?
Yes. Accel IT can provide ongoing patching, endpoint management, backup monitoring, account reviews, vulnerability management and evidence reporting.
This helps prevent the organisation’s maturity from declining as new users, systems and applications are introduced.
