The Essential Eight is a set of eight cyber security mitigation strategies developed by the Australian Cyber Security Centre (ACSC), part of the Australian Signals Directorate (ASD). They represent the baseline security controls that all Australian organisations should implement to protect themselves against the most common cyber threats.
The strategies are not optional recommendations. They are increasingly referenced by cyber insurers as minimum requirements, by clients and tender panels as evidence of security maturity, and by frameworks like SMB1001 as foundational controls. If your business does not have the Essential Eight in place, you are operating below what is now considered an acceptable standard in Australia.
The Essential Eight is organised into three maturity levels. Maturity Level One is the starting point and covers the basic implementation of each strategy. Most small businesses should be aiming for Maturity Level One across all eight controls, with a pathway toward Maturity Level Two as their environment matures.
The Essential Eight Explained
Here is what each of the eight strategies means in plain language, and what we do to implement them for your business.
Application Control
Only approved applications are allowed to run on your systems. This prevents malware, ransomware, and unapproved software from executing on your devices. We configure application control policies to block unauthorised executables while ensuring your team can still use the software they need.
Patch Applications
Third-party applications like web browsers, PDF readers, and business software are kept up to date with security patches. Unpatched applications are one of the most common entry points for attackers. We manage patching across your environment so vulnerabilities are closed quickly, not left open for months.
Configure Microsoft Office Macro Settings
Microsoft Office macros are a common delivery method for malware. We configure macro settings to block macros from the internet, only allow macros in trusted locations, and prevent users from enabling macros in documents received via email. This closes one of the most exploited attack vectors without disrupting legitimate business use.
User Application Hardening
Web browsers and other user-facing applications are configured to reduce their attack surface. This includes blocking ads, disabling Java and Flash, restricting browser extensions, and preventing web browsers from processing unnecessary content that attackers use to deliver exploits.
Restrict Administrative Privileges
Admin accounts are limited to only the people who genuinely need them, and only for tasks that require admin access. Daily work is done on standard user accounts. This prevents a compromised user account from having the permissions to install software, change system settings, or access everything on your network.
Patch Operating Systems
Windows, macOS, and other operating systems are kept up to date with security patches. Operating system vulnerabilities are regularly exploited by attackers, and unpatched systems are a known and preventable risk. We manage OS patching on a schedule that keeps your systems secure without disrupting your business.
Multi-Factor Authentication (MFA)
MFA is enforced on all user accounts, especially for remote access, admin access, and cloud platforms like Microsoft 365 and Google Workspace. MFA prevents the vast majority of account compromises because even if an attacker steals a password, they cannot access the account without the second factor.
Regular Backups
Business-critical data is backed up regularly, backups are stored independently from the production environment, and recovery is tested periodically. This ensures that if ransomware encrypts your files, a server fails, or data is accidentally deleted, your business can recover without paying a ransom or losing everything.
Why the Essential Eight Matters for Your Business
The Essential Eight is not just a government recommendation. It is becoming the standard that the rest of the Australian business ecosystem holds you to.
Not having the Essential Eight in place is a known and preventable risk. If your business suffers a cyber incident and you have not implemented basic controls like MFA, patching, and backups, your insurer, your regulator, and your clients will ask why. Having the Essential Eight implemented is not just about preventing attacks. It is about demonstrating due diligence.
Essential Eight Implementation for Small Business
We implement the Essential Eight for small and medium businesses as part of our managed IT and security services. For most of our managed clients, the majority of these controls are already built into how we manage their environment. For new clients or businesses that need a standalone assessment, we follow a structured approach.
For businesses on our managed IT plans, Essential Eight alignment is built into the service. We do not treat it as a separate project or an add-on. MFA, patching, backup, endpoint protection, and admin privilege management are part of how we manage every client’s environment from day one.
How the Essential Eight Relates to SMB1001
The Essential Eight and SMB1001 are complementary. The Essential Eight provides eight specific technical controls. SMB1001 provides a broader certification framework that includes the Essential Eight controls plus additional governance, policy, and organisational security requirements.
If you implement the Essential Eight, you are well on your way to SMB1001 Bronze and Silver certification. To achieve SMB1001 Gold and above, you need the Essential Eight controls plus documented policies, incident response planning, business continuity processes, and AI governance.
We are an official CyberCert Certification Partner and SMB1001 Gold certified ourselves. We can guide your business through both Essential Eight implementation and SMB1001 certification as a combined pathway, starting with the technical controls and building toward formal certification when you are ready.
Frequently Asked Questions
Is the Essential Eight mandatory for small businesses?
It is not legally mandated for all businesses, but it is the recognised baseline for cyber security in Australia. Cyber insurers, clients, and regulators increasingly treat it as the minimum standard. The Privacy Act requires “reasonable steps” to protect personal information, and the Essential Eight is what most assessors consider reasonable. For practical purposes, if you handle personal or client data, the Essential Eight should be treated as mandatory.
What maturity level should my business aim for?
Most small businesses should aim for Maturity Level One across all eight strategies as the starting point. This covers the foundational implementation of each control. Maturity Level Two adds consistency and coverage. We assess where your business is today and recommend a realistic target based on your size, industry, and risk profile.
How long does it take to implement the Essential Eight?
It depends on your starting point. If your business already has MFA, patching, and backups in place, the remaining controls can often be implemented within a few weeks. If you are starting from scratch, a full implementation typically takes four to eight weeks. For businesses on our managed plans, most controls are already in place from day one.
What is the difference between the Essential Eight and SMB1001?
The Essential Eight is a set of eight technical security controls developed by the ACSC. SMB1001 is a broader certification framework that includes the Essential Eight controls plus governance, policies, and organisational security. The Essential Eight does not have a formal certification process. SMB1001 does, through the CyberCert platform. Many businesses implement the Essential Eight first and then pursue SMB1001 certification to formalise their security posture.
Will the Essential Eight help with cyber insurance?
Yes. Most cyber insurers in Australia ask about MFA, patching, backups, endpoint protection, and admin privilege management, all of which are Essential Eight controls. Having these in place strengthens your application, may reduce your premiums, and ensures your claim is not denied because you lacked basic protections at the time of an incident.
Do you provide an Essential Eight assessment?
Yes. We assess your current environment against each of the eight strategies, identify gaps, and provide a prioritised remediation plan. For businesses on our managed plans, this assessment is included. For standalone assessments, we provide a fixed-price engagement with a clear report and actionable recommendations.
