• Strong knowledge of frameworks such as NIST CSF, ISO 27001, VPDSS, ASD ISM or CIS.
• Understanding of security controls across IT, OT, Cloud, SaaS and Managed Services environments.
• Ability to interpret assurance artefacts and work with suppliers to address security gaps and contractual security requirements.
• Strong analytical, communication and stakeholder engagement skills.
• Relevant qualifications, ideally with certifications such as CISSP, CTPRP, CTPRA, CRISC or ISO 27001.
