Cybersecurity is not just a concern for large enterprises. Small and medium-sized enterprises (SMEs) are increasingly becoming targets for cyberattacks due to perceived weaker security defenses. As a result, ISO 27001 certification has gained attention among SMEs striving to strengthen their information security posture. But what exactly are the ISO 27001 requirements, and is certification truly worth it for smaller businesses?
What is ISO 27001?
ISO 27001:2022 is the latest version of the international standard for Information Security Management Systems (ISMS). It provides an updated and structured framework for managing sensitive company information to ensure its confidentiality, integrity, and availability. The 2022 revision includes notable changes aimed at improving adaptability, risk management, and integration with modern digital environments—making it especially relevant for today’s SMEs.
Core ISO 27001 Requirements ISO 27001:2022 includes both mandatory requirements and a revised Annex A with 93 controls (down from 114), grouped into four main themes. Here’s a breakdown of the standard’s requirements:
- Context of the Organization
- Understand internal and external issues that influence information security.
- Identify stakeholders (e.g., clients, partners, regulators) and their requirements.
- Leadership
- Top management must demonstrate leadership and commitment to the ISMS.
- Establish an information security policy and assign clear roles and responsibilities.
- Planning
- Conduct a comprehensive risk assessment.
- Define risk treatment options aligned with the new control structure.
- Establish measurable security objectives.
- Support
- Ensure necessary resources, competencies, and awareness across the organisation.
- Maintain updated documentation and secure communication practices.
- Operation
- Implement and manage information security processes and risk treatments.
- Monitor, document, and control operational changes and exceptions.
- Performance Evaluation
- Measure ISMS performance.
- Conduct internal audits and management reviews.
- Improvement
- Address nonconformities through corrective actions.
- Drive continuous improvement of the ISMS.
Annex A Controls (ISO 27001:2022) The 2022 version reduces and restructures the controls into four themes:
- Organizational Controls (37)
- People Controls (8)
- Physical Controls (14)
- Technological Controls (34)
This streamlined structure helps SMEs more easily align their controls with operational needs. The introduction of “attributes” also allows better cross-referencing and filtering of controls based on cybersecurity concepts (e.g., threat type, risk treatment).
Benefits of ISO 27001 Certification for SMEs
- Modernised Framework: Tailored for current cyber risks and digital environments.
- Enhanced Security Posture: Reduces the risk of data breaches and system compromise.
- Customer Trust: Signals to clients that information security is taken seriously.
- Regulatory Compliance: Helps meet local data protection regulations such as the Australian Privacy Act.

Challenges SMEs Might Face
- Resource Constraints: Budget and personnel limitations can make implementation seem overwhelming.
- Learning Curve: Understanding the changes from the 2013 to 2022 version requires time.
- Ongoing Maintenance: Post-certification maintenance is essential to retain compliance.
Is ISO 27001 Certification Worth It for SMEs?
Despite initial efforts, ISO 27001:2022 offers long-term value. SMEs that deal with sensitive data, serve enterprise clients, or must meet regulatory obligations will particularly benefit. Even without full certification, aligning operations with ISO 27001:2022 builds a strong cybersecurity foundation.
