Internal Audit Services for ISO 27001 & SOC 2: Ensuring Strong Information Security and Compliance
Information security compliance has evolved from a regulatory checkbox exercise to a strategic business imperative. Organisations operating in diverse sectors—from financial services to healthcare, technology, and professional services—must navigate complex regulatory environments while maintaining operational efficiency.
Internal audits are a vital part of this process, providing assurance that your Information Security Management System (ISMS) or Service Organisation Controls (SOC) are working as intended and meeting the relevant requirements. At Information Security Consultants (ISC), we deliver omprehensive internal audit services for both ISO 27001 and SOC 2 frameworks, helping Australian businesses identify risks, close gaps, and get audit-ready with confidence.
Why Are Internal Audits Important?
Internal audits help you to:
- Verify ongoing compliance with ISO 27001 and SOC 2
- Spot control gaps and process weaknesses before an external audit
- Drive continual improvement of your security controls and processes
- Demonstrate due diligence to clients, regulators, and partners
