Frequently Asked Questions

ISO/IEC 27001 is an international standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). It helps organizations protect sensitive information and demonstrate strong security governance.

ISO 27001 is not legally mandatory, but it strongly supports compliance with the Australian Privacy Act and is often required by enterprise customers and international partners.

Depending on organizational size and readiness, ISO 27001 certification typically takes 3 to 12 months. A readiness or gap assessment can significantly reduce timelines.

Costs vary based on scope and complexity, generally ranging from AUD 15,000 to AUD 120,000+, including preparation and certification audits.

ISO 27001 certification follows a three-year cycle, with annual surveillance audits and a full recertification audit every three years.
