What Sets Us Apart

Family Office & Private Client Experience

DSC understands the sensitive requirements of Family Offices. Confidentiality, privacy and anonymity are non-negotiable. We protect both information and client identity, and never use Family Office names, relationships, structures or engagements publicly without express permission.

Long-Term Accountability

Founded in 1997, DSC is built around long-term client relationships rather than transactional projects. We remain accountable for implementation, ongoing operations, security, resilience and continual improvement.

Cybersecurity, Managed IT & Secure AI Together

DSC integrates managed IT, cybersecurity, Microsoft 365 security, data protection, technology governance and Secure AI adoption. This allows clients to manage technology and emerging AI risk as one connected environment rather than separate projects.

Commonly Asked Questions

We are particularly interested in engagements with Family Offices, private enterprises and not-for-profit organisations involving cybersecurity, Secure AI governance, Shadow AI risk, Microsoft 365 security, Essential Eight uplift, managed IT transitions, technology governance, business continuity and infrastructure modernisation. We are best suited to organisations looking for a long-term accountable technology partner rather than a transactional IT supplier.

DSC combines managed IT operations with cybersecurity, Microsoft 365 security, business continuity, technology governance and Secure AI advisory. We have operated since 1997 and focus on remaining accountable for long-term technology outcomes rather than simply resolving individual IT issues. This integrated approach is particularly valuable for Family Offices and organisations handling sensitive information.

DSC deliberately operates a relationship-led rather than high-volume model. Capacity is managed so clients have access to the appropriate technical, service and leadership resources, including true 24×7 support where required. For larger projects and transitions, we review capacity before commencement and agree resource requirements and delivery timing with the client.

Yes. DSC is Australian-owned, with team members across Australia and our Australian Head Office in Cottesloe, Western Australia. We provide nationally coordinated services and true 24×7 support to clients across Australian time zones and to executives travelling internationally. Our Family Office work and strategic direction also extend across Asia-Pacific, particularly Australia, New Zealand and Singapore.

DSC helps organisations understand existing AI use, identify Shadow AI, establish approved platforms and use cases, protect sensitive information, assess AI vendors and integrations, implement identity and security controls, develop AI policies and establish ongoing governance. Our objective is not to prevent useful AI adoption; it is to make adoption deliberate, secure and accountable.
