What is the Essential Eight?

You might have heard 'Essential Eight' mentioned by your IT person, your insurer, or a government client. It's Australia's primary cyber security framework, developed by the Australian Signals Directorate (ASD) and the Australian Cyber Security Centre (ACSC). It sounds technical, but the core idea is straightforward — and it's becoming increasingly relevant for businesses of all sizes.

The short answer

The Essential Eight is a set of eight baseline strategies designed to prevent cyber attacks and limit their damage. They're not theoretical — they're practical controls like keeping software patched, using multi-factor authentication, and restricting who can install applications. The framework includes maturity levels (0 through 3) so businesses can assess where they stand and improve over time. In 2026, alignment with the Essential Eight is increasingly expected for government contracts, cyber insurance, and supply chain partnerships.

What to consider

Application control

Only approved software can run on your systems — this stops malware and unauthorised programs from executing in the first place.

Patching applications

Keeping your software up to date closes the security holes that attackers exploit — vulnerabilities can be targeted within hours of being made public.

Configuring Microsoft Office macros

Macros are a common way malware gets in through email attachments — restricting them to trusted sources blocks a major attack path.

User application hardening

Disabling unnecessary features in web browsers, PDF readers, and Office apps reduces the ways an attacker can get a foothold.

Multi-factor authentication

Requiring a second form of verification beyond a password stops most account compromises — even if a password is stolen or guessed.

Backups and admin privileges

Regular tested backups mean you can recover from ransomware, and restricting admin access limits how far an attacker can go if they get in.

Who this guide is for

Business owners who've heard about the Essential Eight but aren't sure what it means for them.
Businesses applying for government contracts or tenders that require cyber security compliance.
Anyone whose cyber insurer has started asking about their security controls.
IT managers wanting to understand the framework before starting an implementation project.

What to do next

Understand where you stand. Most small businesses are at Maturity Level 0 or 1 — knowing your starting point is the first step.
Start with the basics. MFA, patching, and backups give you the biggest security improvement for the least effort — tackle those first.
Don't try to do everything at once. The maturity model is designed for gradual improvement — aim for Level 1 across all eight strategies before pushing any single one to Level 3.
Get an assessment. An Essential Eight assessment maps your current state against the framework and gives you a clear list of what needs fixing.
