Essential Eight

Australia's leading cybersecurity framework — assessed and implemented by ASE Tech

The Essential Eight is the Australian Signals Directorate's foundational cybersecurity framework — eight mitigation strategies that form the baseline for cyber resilience across Australian government, enterprise, and critical infrastructure. Updated in September 2025, it is now explicitly linked to SOCI Act obligations and is the most widely mandated cybersecurity standard in Australia.

ASE Tech delivers end-to-end Essential Eight services: from your initial maturity assessment through to uplift implementation and ongoing managed compliance. We give you a measurable maturity score, a prioritised remediation roadmap, and continuous visibility into your position — not just a report and a handshake.

Book an Essential Eight assessment
Strategy 1
Application Control
Prevent unapproved applications from executing across your environment, reducing attack surface significantly.
Strategy 2
Patch Applications
Rapidly remediate known vulnerabilities in internet-facing and third-party applications before they can be exploited.
Strategy 3
Configure Microsoft Office Macros
Block macros from the internet and restrict execution to trusted, signed sources to prevent malware delivery.
Strategy 4
User Application Hardening
Disable dangerous browser features and ensure internet-facing applications are locked to minimum required functionality.
Strategy 5
Restrict Admin Privileges
Limit administrative access to the minimum necessary — a critical control against lateral movement and ransomware spread.
Strategy 6
Patch Operating Systems
Keep operating systems current and eliminate known exploits that attackers actively target in Australian environments.
Strategy 7
Multi-Factor Authentication
Enforce MFA across all users, systems, and remote access points — the single highest-impact control against credential attacks.
Strategy 8
Regular Backups
Maintain tested, isolated backups of critical data and systems so recovery from ransomware is measured in hours, not weeks.

Essential Eight Maturity Assessment — where do you sit?

The ASD defines four maturity levels (ML0–ML3) for Essential Eight implementation. Most Australian organisations start between ML0 and ML1. ASE Tech begins every engagement with a structured readiness assessment that gives you a current-state maturity score across all eight strategies, a prioritised remediation roadmap, and clear milestones toward your target level.

Essential Eight maturity model

Understanding your maturity level

The ASD's Essential Eight Maturity Model measures your implementation across four levels. ASE Tech helps Australian organisations assess their current position and build a roadmap to their required level.

ML0
Not implemented
One or more strategies are not implemented or not on the roadmap. Highest exposure to common cyber threats.
ML1
Partly aligned
Partially implemented controls that reduce risk but leave significant gaps. Most Australian SMEs start here.
ML2
Mostly aligned
Controls are implemented and consistently applied. Recommended for regulated industries and government suppliers.
ML3
Fully aligned
Highest maturity — fully implemented controls with continuous monitoring. Required for critical infrastructure operators.

Critical Infrastructure

Operating in a SOCI-regulated sector?

If your organisation owns or operates critical infrastructure assets across energy, water, transport, telecommunications, or any other SOCI Act sector, your cybersecurity obligations go beyond best practice — they're a legal requirement. The CIRMP mandatory deadline has passed. CISC audits are active. ASE Tech's SOCI compliance program integrates directly with your cybersecurity framework to ensure you meet your obligations and can demonstrate it under audit.

Why ASE Tech

ISO 27001 certified. Engineer-led. Proven on Australia's most critical infrastructure.

ISO 27001 certified

We hold ISO 27001 certification ourselves — meaning we don't just advise on information security standards, we operate to them. Your security advice comes from a team that lives it.

No vendor agenda

Big-tech rebates and lock-ins mean many providers push tools that suit the vendor, not the client. ASE Tech selects technology on merit — giving you better fit, better value, and better outcomes.

Critical infrastructure expertise

We connect and secure more than 20% of Australia's renewable energy assets. Our OT security, SOCI compliance, and AESCSF experience is unmatched by generalist MSPs.

24/7 managed monitoring

Our SOC operates around the clock — detecting, triaging, and responding to threats so your team can focus on running your business.

Measurable outcomes

We report on maturity level progression, risk reduction, and compliance status — not just activity. You always know where you stand.

Continuous optimisation

Cyber threats evolve constantly. We don't set and forget — we continuously tune your controls, update your posture, and keep you ahead of emerging attack patterns.

FAQs

Cybersecurity services — frequently asked questions

Common questions from Australian businesses and critical infrastructure operators about managed cybersecurity.

The Essential Eight is the Australian Signals Directorate's (ASD) set of eight priority cybersecurity strategies. While it isn't legally mandated for all Australian businesses, it's effectively required for federal government agencies and is increasingly expected of suppliers and critical infrastructure operators. If your organisation is subject to the SOCI Act, your CIRMP must align with a recognised framework — and the Essential Eight is one of the most commonly adopted. Even outside regulated sectors, implementing the Essential Eight is the most effective baseline you can put in place against the threats targeting Australian organisations today.
It depends on your industry and risk profile. For most Australian SMEs and enterprises, Maturity Level 2 is the recommended target — controls are consistently applied across the organisation. ML3 is required for critical infrastructure operators under SOCI and for organisations supplying defence or government. ML1 is the absolute minimum. ASE Tech's assessment will give you a current-state score and a clear recommendation on your target level based on your regulatory obligations and threat exposure.
The Essential Eight is a specific set of eight technical controls developed by the ASD for the Australian context — it's prescriptive, actionable, and directly tied to the most common attack vectors targeting Australian organisations. ISO 27001 is a broader international information security management standard that covers governance, processes, people, and technology across your whole organisation. Many Australian businesses pursue both: Essential Eight provides the technical baseline, ISO 27001 provides the governance framework. ASE Tech is ISO 27001 certified and can help you implement either or both.
ASE Tech's cybersecurity assessment typically covers three phases: discovery (understanding your current environment, assets, and controls), gap analysis (benchmarking against Essential Eight, ISO 27001, or your relevant framework), and reporting (a prioritised remediation roadmap with clear effort and impact ratings). For SOCI-regulated organisations, we also benchmark against AESCSF and CIRMP requirements. Assessments can be completed remotely or on-site and typically take 2–4 weeks depending on the size and complexity of your environment.
Yes — critical infrastructure is our core. We connect and secure more than 20% of Australia's renewable energy assets and work across energy, water, transport, and telecommunications sectors. We have deep expertise in OT security, AESCSF compliance, and SOCI Act obligations including CIRMP implementation and audit preparation. View our dedicated SOCI compliance services page for more detail.
ASE Tech works across critical infrastructure (energy, water, transport, telecoms), financial services, healthcare, professional services, and education. Our deepest specialisation is in environments where downtime carries significant operational, safety, or regulatory consequences — particularly OT and industrial environments. We have specific experience with SOCI Act, AESCSF, CPS 234, and Essential Eight compliance obligations across these sectors.
