2025 Cyber Reality: Why The Essential 8 isn't enough...

For years, government departments, public outlets, media outlets, and IT service providers have positioned the Australian Cyber Security Centre’s (ACSC) Essential 8 as the gold standard for cybersecurity for Australian businesses.

‍

However, as cyber threats evolve, more influential organisations, like IT providers and insurance carriers, have begun promoting the Essential 8 as a must-have cybersecurity framework. The reality is that while it offers a starting point, it is far from sufficient in 2025, leaving businesses exposed to significant risk.

‍

The Essential 8: A Limited Approach to a Complex Threat Landscape

Initially developed as a baseline framework for businesses and government agencies, the Essential 8 was never designed to address the broad range of cyber threats businesses face.

Over time, its limitations have become increasingly apparent:

• Narrow Focus – While the Essential 8 prioritises patching, application control, and privileged access management, it lacks a holistic approach to overall business security and security risk management.
• One-Size-Fits-All Mentality – The prescriptive nature of Essential 8 fails to accommodate the unique risk profiles of different businesses.
• Deficiencies in Key Areas – The framework does not sufficiently address newer core challenges like supply chain security, insider threats, or incident response, which are critical in today’s business environment.
• Not Built for Modern Threats – Attackers are leveraging AI-driven threats, advanced, evasive ransomware, and social engineering tactics that the Essential 8 does not effectively counter.
• Lack of Evolution – Since its introduction in 2017, the Essential 8 has remained largely unchanged. Meanwhile, the threat landscape has evolved significantly, exposing businesses that rely solely on this framework to emerging cyber risks.

‍

For organisations relying solely on this framework, a false sense of security is one of the greatest risks. The unfortuneate truth is compliance with the Essential 8 does not equate to being secure against today’s advanced cyber threats.

Cybersecurity Complacency Is a Business Killer: Why You Need a Smarter Strategy

Cyber security is not just an IT issue but a core business risk that boards, directors, C-Suite and business leaders must be aware of. Leaders who depend on an outdated or incomplete frameworks inadvertently expose their companies to financial, operational, and reputational damage.

Considerthe risks of relying on an inadequate cybersecurity strategy:

• Operational Downtime – A single ransomware attack could disrupt critical business operations, and the Essential 8 alone cannot prevent it.
• Regulatory Non-Compliance – Businesses need to demonstrate strong cybersecurity measures that align with evolving regulatory requirements - not just adhere to a limited checklist.
• Supply Chain Vulnerabilities – Insufficient security controls can create a ripple effect if your business depends on third-party vendors, increasing exposure to potential breaches.
• Contractual and Audit Obligations – If your organisation holds a major contract with a large enterprise, expect to face annual cybersecurity audits. The reality is simple: Essential 8 will not be enough to pass, and failure to meet evolving security expectations could mean losing your contract altogether. Large businesses demand mature cybersecurity frameworks, not outdated checklists. If your security posture doesn't stack up, they will move on to a supplier that does

To manage risk effectively in 2025, businesses need a more comprehensive and adaptable cyber security framework - one that moves beyond the Essential 8.

Risk Management Over Outdated Technical Controls: Why CIS Controls v8 Is the Better Choice

The CIS Controls v8 frameworkis a true risk management tool, designed to protect businesses from real-world cyber threats - not just serve as a box-ticking exercise like the Essential 8. Originally developed by the Center for Internet Security (CIS), this framework was created to help businesses of all sizes implement practical, prioritised security measures to reduce cyber risk.

Unlike the Essential 8, CIS Controls was designed with business risk in mind from the outset, ensuring relevance across industries and evolving threat landscapes.

‍

• Risk-Based Adaptability – Instead of a rigid, out of date checklists, CIS Controls allow businesses to implement security measures based on their unique risk exposure.
• Scalability for All Businesses – Whether a small business or a large enterprise, the framework provides practical guidance adaptable to different organisational sizes.
• Holistic Security Coverage – CIS Controls address critical security areas such as incident response, asset management, continuous monitoring, data classification, and identity access management - all essential in today’s cybersecurity landscape.
• Third-Party Risk Management – Unlike the Essential 8, CIS Controls incorporate strategies for managing cybersecurity risks within supply chains and vendor relationships.
• A Strong Foundation for ISO27001 Compliance – For businesses wanting to pursue ISO 27001 certification, CIS Controls v8 serves as a solid baseline framework to build into ISO 27001. This is especially valuable for organisations with contractual obligations for supply chain compliance, ensuring alignment with industry-recognised security standards.
• Continuous Evolution – Unlike the Essential 8, which has remained stagnant since 2017, the CIS Controls have been continuously updated to address emerging cyber threats, with major revisions including CIS Controls v7 in 2018 and CIS Controls v8 in 2021. These frequent updates ensure that businesses are equipped with security measures that evolve alongside modern threats.

For business leaders who take cybersecurity and risk management seriously, there is no room for outdated, inadequate frameworks.

CIS Controls v8 is the absolute minimum standard you should be implementing. Relying on the Essential 8 alone is not a cybersecurity strategy—it’s an ever increasing liability. If your business is serious about security and resilience, you need a framework built for modern threats, not a checklist designed for yesterday’s risks.
