Our cyber security assurance services provide independent assurance over security, risk and governance controls, helping you respond to customer assurance requests, procurement reviews and regulatory expectations.
Australian organisations operating business-critical technology environments are frequently required to provide independent assurance over cyber security risks by external stakeholders. In practice, this demand is most often driven by enterprise customer requirements, offshore counterparties and Australian regulatory expectations rather than internal compliance initiatives.
Grant Thornton Australia provides independent cyber security assurance for organisations operating complex technology environments, including critical infrastructure, where assurance outcomes need to be defensible and usable. We deliver assurance against recognised criteria and minimum security standards set by regulators and industry bodies, as well as widely adopted cyber security frameworks.
Our cyber security assurance services include:
SOC 2 and SOC 3 audits
SOC 2 and SOC 3 audits provide independent assurance over controls aligned to the Trust Services Criteria, commonly required to support customer assurance, procurement and vendor risk management. We support both Type I and Type II engagements, with scoping and execution focused on producing reports that are credible, usable and proportionate to underlying risk.
ACSC Essential Eight, NIST-CSF and other cyber maturity assessments
Independent cyber maturity assessments benchmark your security posture against recognised frameworks, including the ACSC Essential Eight, NIST Cybersecurity Framework (NIST-CSF) and other relevant standards. These engagements provide a defensible view of current state, control effectiveness and priority gaps aligned to Australian threat and regulatory expectations.
Regulatory compliance cyber reviews (APRA, ASIC, OAIC)
Targeted cyber reviews to support alignment with Australian regulatory expectations, including APRA CPS 234, ASIC guidance and Privacy Act obligations. These reviews focus on governance, control design and operating effectiveness, with a clear emphasis on evidence quality and defensibility.
Penetration testing and technical assessments
Penetration testing and technical security assessments are designed to validate the effectiveness of key controls under realistic operating conditions. Testing is risk based and prioritised according to exposure and business impact, supporting assurance and remediation decisions.
Cybersecurity certification
Support for recognised cybersecurity certifications and attestations, including Microsoft Supplier Security and Privacy Assurance (SSPA), ISO IEC 27001 and PCI DSS. We help you define the requirement, confirm evidence expectations and complete the assessment or certification in a way that is proportionate to risk and stands up to external scrutiny.
We simplify the technical complexity of cyber assurance by translating control evidence and technical findings into clear, actionable insights that decision-makers can rely on. This helps you meet assurance and compliance expectations efficiently while strengthening cyber resilience in support of broader business objectives.
