Essential Eight compliance

Essential Eight compliance for Australian businesses

The Essential Eight is the Australian Signals Directorate’s baseline for cybersecurity. Our assessments are led by our CISO, certified through TAFE Queensland’s Essential Eight Assessment Course. We help you reach your target maturity and prepare reports for tenders and insurers.

Each strategy, and how we put it in place

The Essential Eight is a set of mitigation strategies from the Australian Signals Directorate. We do not just write the report. We put the controls in with Microsoft 365, Intune and our managed security tools, then document them.

1. Application control

Only approved software can run

ThreatLocker on every computer we manage, with ringfencing so approved apps cannot be turned against you. How staff request an app.

  • ThreatLocker

2. Patch applications

Close known holes in the software you use

Browsers, Office, PDF readers and other apps are updated automatically through Intune, in stages so a bad update does not reach everyone at once.

  • Microsoft Intune

3. Configure Microsoft Office macro settings

Block untrusted macros

Macros from the internet are blocked by Intune policy. Signed macros from trusted publishers are allowed only where the business needs them. When Excel blocks a macro.

  • Microsoft Intune
  • Microsoft 365 Apps

4. User application hardening

Turn off risky features in browsers and readers

Browsers and PDF readers are hardened, and Attack Surface Reduction rules are enforced through Intune. When an ASR rule blocks an app.

  • Microsoft Defender for Endpoint
  • Microsoft Intune

5. Restrict administrative privileges

Limit who can change your systems

Standard users do not have local admin rights. Privileged accounts are separate, with access granted only when it is needed, through Microsoft Entra ID.

  • Microsoft Entra ID
  • Microsoft Intune

6. Patch operating systems

Keep Windows and macOS current

Windows Update for Business is managed through Intune, with testing rings so updates do not disrupt your team.

  • Windows Update for Business
  • Microsoft Intune

7. Multi-factor authentication

A password alone never gets in

Multi-factor sign-in on every account through Entra Conditional Access. Phishing-resistant methods such as FIDO2 keys and the Authenticator app are preferred over SMS. Moving Authenticator to a new phone.

  • Microsoft Entra ID
  • Conditional Access

8. Regular backups

Backups you can actually restore

Automated cloud backup of Microsoft 365, computers and servers, kept apart from your systems, with restores tested regularly. Backup and disaster recovery.

  • Cloud backup

The four maturity levels in plain words

ASD’s maturity model measures how well each strategy is in place, from Level Zero to Level Three. Each level is built to stop a more capable attacker.

Maturity Level Zero

Weaknesses that leave the business open to common attacks.

Maturity Level One

Protects against opportunistic attackers using widely available tools. The right starting point for most small businesses.

Maturity Level Two

Protects against attackers willing to spend more time and effort. Required for non-corporate Commonwealth entities.

Maturity Level Three

Protects against more adaptive attackers who target specific organisations.

Not sure which maturity level you need?

Most small businesses should target Maturity Level One first. If you handle sensitive government data or health records, you may need Level Two or higher. We look at where you are now and recommend a target for your industry, size and risk.

Need an Essential Eight report for a tender?

Government contracts and larger customers often ask for evidence of Essential Eight alignment, and they want it quickly. We assess your current controls, close the gaps and write a detailed report on every strategy. There is no ASD certificate, so the report is your proof.

Start with the Essential Eight Discovery Workshop, A$695 ex GST. You get a gap rating for each of the eight strategies and the blockers to fix before a formal assessment.

Essential Eight compliance questions

No. Non-corporate Commonwealth entities must reach Maturity Level Two under the Protective Security Policy Framework. For private businesses it is not a legal requirement, but government buyers, larger customers and cyber insurers often ask for it. If you tender for government work, expect to be asked.

No. The ASD does not issue an Essential Eight certificate. You show compliance with a detailed report that sets out each control, how your business meets each strategy and your current maturity level. Our CISO-led team writes that report for you.

Most small and medium businesses should start with Maturity Level One. It covers the basics: patching, multi-factor sign-in, application control and backups. If you handle sensitive government data, health records or financial information, you may need Level Two or higher. We look at your risk and recommend a target.

It depends on where you start. Businesses already on Microsoft 365 with a managed IT provider usually have part of the work done, and existing GCIT clients are often partly aligned through our standard security baseline. After the assessment you get a plan with the work and the timeframe.

They work together. ISO 27001 is an international standard for the whole information security management system, including policies, risk management and governance. The Essential Eight focuses on eight technical strategies. GCIT is certified to ISO 27001 and uses both. Learn more about our cybersecurity approach.

It can help. Insurers ask about the same controls, such as multi-factor sign-in, patching, endpoint protection and backups, and a clear report makes those questions easy to answer. For one critical infrastructure client we look after, documented controls took a quoted premium from $105,000 to $66,500 and doubled its cover to $5 million.
