110
Client Organisation
The client is a leading Australian financial services provider offering payment solutions and banking technologies to more than 150 institutions across multiple industries. With a reputation for reliability and innovation, the organisation plays a critical role in enabling secure, seamless transactions across the Australian market. The business continues to invest in technology and infrastructure to strengthen its competitive advantage and meet evolving regulatory and customer expectations.
Project Overview
Since 2020, the client has been undertaking a program of initiatives to uplift IT security and modernise technology infrastructure. These efforts were designed to enhance cybersecurity resilience, strengthen operational efficiency, and improve customer confidence in its services. A key priority was achieving alignment with the Australian Cyber Security Centre’s (ACSC) Essential Eight framework. Delivering this uplift required extensive coordination across internal teams and external IT security advisors, while managing competing business priorities.
Sedha's Role
Sedha Consulting was engaged to plan and deliver a 12-month program to uplift Essential Eight IT Security Control Maturity Levels. Working alongside the Chief Information Technology Officer and business unit leaders, Sedha oversaw the implementation of security controls across multiple domains, including application whitelisting, privilege restriction, multi-factor authentication, patching and data backup. Sedha coordinated engagement between stakeholders and external vendors, maintained structured governance through a steering committee, and provided clear progress reporting. This ensured that the project advanced with discipline, transparency, and measurable milestones.
Results
The engagement delivered a measurable uplift in cybersecurity maturity across the organisation. The Essential Eight controls were embedded into business operations, significantly reducing risk exposure and strengthening resilience against cyber threats. Technology infrastructure was modernised to support secure service delivery and regulatory compliance. As a result, the organisation enhanced its position as a trusted provider of secure payment and financial services in Australia. The work also established a foundation for future digital transformation and operational efficiency improvements.
