Are you aware that almost 50% of cyberattacks focus on small and medium-sized enterprises, yet many of them lack a structured security framework? In the absence of a defined strategy, even well-equipped organisations find it challenging to prioritise the most important controls.
That’s why cybersecurity frameworks are essential. Two of the most prominent ones are the Essential 8, developed by the Australian Cyber Security Centre (ACSC), and the NIST Cybersecurity Framework (CSF), crafted by the U.S. National Institute of Standards and Technology. Both frameworks aim to enhance organisational resilience but follow distinctly different methodologies, one being prescriptive and tactical, while the other is strategic and risk-oriented.
In this blog, we’ll break down Essential 8 vs NIST, explore their similarities and key differences, and provide guidance to help you determine which framework best suits your business needs.
TL;DR
- Essential 8: A prescriptive, tactical Australian framework (ACSC) for immediate, baseline security improvements, ideal for small and medium-sized businesses and government agencies.
- NIST CSF: A flexible, strategic, risk-based U.S. framework (NIST) for comprehensive, long-term security management, valuable for large, global enterprises.
- Best Approach: The most effective security practices often combines both, using the Essential 8 for a quick, actionable security foundation and the NIST framework for strategic governance and risk management.
What is the Essential 8 Framework?
The Essential 8 cybersecurity framework was developed by the Australian Cybersecurity Centre (ACSC) as a practical, baseline approach to managing cybersecurity. Born from extensive analysis of successful cyberattacks and mitigation strategies, this framework represents the most effective strategies for preventing and mitigating cyber threats.
The ASD Essential 8 operates on a foundational principle: focus on the most critical security controls that deliver maximum impact. Rather than overwhelming organisations with extensive requirements, it provides eight specific, actionable strategies that address the most common attack vectors used by cybercriminals.
The Eight Core Strategies
The Essential 8 framework consists of these fundamental 8 mitigation strategies:
Prevention Strategies:
- Application Control (whitelisting) – Preventing execution of unapproved/malicious applications
- Patch Applications – Timely security updates for software vulnerabilities
- Configure Microsoft Office Macro Settings – Controlling macro execution to prevent malware
- User Application Hardening – Securing web browsers and PDF viewers
Limitation Strategies:
- Restrict Administrative Privileges – Implementing the principle of least privilege
- Patch Operating Systems – Maintaining up-to-date system security
- Multi-Factor Authentication – Adding layers of authentication security
Recovery Strategy:
- Regular Backups – Ensuring data recovery capabilities and business continuity.
Each strategy in the Essential 8 is supported by three maturity levels (Level 1, 2, and 3). These levels allow organisations to progressively strengthen their cyber security posture:
- Level 1: Basic protection against common cyber threats.
- Level 2: Stronger, consistent defences against more targeted attacks.
- Level 3: Robust security measures designed to counter advanced, sophisticated threats.
The Essential 8 is prescriptive; it tells businesses exactly what to do to reach certain maturity levels. In Australia, many government agencies and contractors are required to comply with it, making it highly relevant for organisations operating within the region.
Ensure your organisation is prepared for evolving cyber risks by scheduling a consultation with us to assess your Essential 8 or NIST implementation and design a strong, risk-based security plan.
What is the NIST Cybersecurity Framework?
The NIST Cybersecurity Framework, developed by the National Institute of Standards and Technology, represents a comprehensive, risk-based approach to cybersecurity management. Originally created to protect critical infrastructure, it has evolved into a globally recognised standard for organisations of all sizes and sectors.
The NIST framework operates on flexibility and adaptability principles. Rather than prescribing specific technologies or solutions, it provides a structured approach to identifying, assessing, and managing cybersecurity risks. This security framework recognises that cybersecurity is not a one-size-fits-all proposition and must align with business objectives and risk tolerance.
The Five Core Functions
The NIST framework organises cybersecurity activities into five concurrent and continuous functions:
- Identify: Understand assets, risks, and governance requirements.
- Protect: Safeguard critical systems and data through controls.
- Detect: Implement processes to quickly identify incidents.
- Respond: Have plans in place to mitigate the impact of incidents.
- Recover: Ensure timely recovery of operations and data.
NIST CSF is a widely recognised cyber security framework worldwide, especially in industries where compliance and robust risk management are essential. It is particularly valuable for large enterprises, multinational organisations, and critical infrastructure sectors.
Can a non-U.S. company use the NIST framework?
Yes, the NIST Cybersecurity Framework is a globally recognised standard due to its flexibility and comprehensive, risk-based approach. It can be adapted for any organisation worldwide.
What are the Key Differences Between Essential 8 vs NIST Frameworks?
Aspect |
Essential 8 |
NIST Cybersecurity Framework |
|---|---|---|
| Origin & Authority | Australian Cybersecurity Centre (ACSC) — Government-mandated for Australian agencies | National Institute of Standards and Technology (US) — Voluntary global standard |
| Scope & Approach | Prescriptive, focused on 8 specific technical controls | Comprehensive, risk-based framework covering the entire cybersecurity lifecycle |
| Target Audience | All organisations, particularly the Australian government and critical infrastructure | Organisations of all sizes globally, especially those in the critical infrastructure |
| Implementation Complexity | Straightforward, actionable strategies with clear implementation guidance | Flexible but requires significant customisation and strategic planning |
| Compliance Requirements | Mandatory for Australian government agencies, strongly recommended for critical infrastructure | Voluntary adoption, though often referenced in regulatory requirements |
| Level of Detail | Highly specific technical controls with measurable outcomes | High-level strategic framework, requiring detailed implementation planning |
| Maturity Levels | Three maturity levels (1, 2, 3) for each strategy | Implementation tiers (Partial, Risk-Informed, Repeatable, Adaptive) |
| Focus Area | Prevention-focused with emphasis on common attack vectors | Holistic approach covering prevention, detection, response, and recovery |
| Geographic Relevance | Primarily an Australian context with international applicability | Global applicability across industries and jurisdictions |
| Resource Requirements | Lower initial investment, focused implementation | Higher resource investment for comprehensive implementation |
| Measurability | Clear, objective metrics for each strategy | Requires development of custom metrics aligned with business objectives |

Which Framework Should Your Business Use?
Choosing between the Essential 8 and NIST depends largely on your organisation’s location, industry, and compliance requirements:
For Australian Organisations
The Essential 8 is often the most practical starting point, especially for those in government or critical infrastructure. It offers clear compliance alignment with local regulations and a cost-effective path to achieving a strong baseline of security. Larger Australian enterprises with international operations may find it insufficient for comprehensive risk management.
For Global and Multinational Enterprises
The NIST Cybersecurity Framework provides the flexibility and comprehensiveness needed for complex, multi-jurisdictional operations. Its risk-based approach aligns well with diverse business units and regulatory environments.
Which framework is better for a small business?
For small businesses, the Essential 8 is typically the most practical starting point due to its clear, actionable, and less resource-intensive nature. It provides a defined checklist for achieving a strong baseline of security without requiring significant upfront strategic planning.
Can Essential 8 and NIST be Used Together?
Yes, they can. Many organisations are discovering that Essential 8 and NIST work exceptionally well together rather than as competing alternatives:
Essential 8 as Foundation: Implement Essential 8 strategies as baseline security controls, providing immediate risk reduction and a clear implementation roadmap.
NIST as a Strategic Framework: Use the NIST’s five functions to build a complete cybersecurity strategy, including governance, risk management, and incident response processes.
This integrated approach combines tactical implementation (Essential 8) with strategic planning (NIST), allowing you to address immediate security needs while building long-term cyber resilience.
Conclusion
The choice between the Essential Eight and NIST isn’t an “either-or” decision. The Essential 8 excels at providing focused, practical security controls, making it ideal for organisations seeking straightforward implementation and Australian regulatory compliance. The NIST framework, in contrast, offers the strategic depth and flexibility required for comprehensive cybersecurity risk management, particularly for complex, international organisations.
Ultimately, the best practice often combines the two frameworks: using the Essential 8 as foundational security measures and leveraging NIST for overall cybersecurity governance. Success in cybersecurity requires more than just selecting the right framework; it demands consistent application, regular assessment of risk profile, and adaptation to the evolving threat landscape.
