About DSC
DSC / Delta Sierra Consulting is an Australian-owned cybersecurity, managed IT and Secure AI governance firm founded in 1997. DSC has team members across Australia, coordinated through our Australian Head Office in Perth.
Our true 24×7 operating model supports clients across Australia and executives working or travelling internationally. DSC also has a deliberate Asia-Pacific direction, with particular Family Office focus across Australia, New Zealand and Singapore.
DSC works with Family Offices, their private enterprises, not-for-profit organisations and other clients where privacy, resilience, continuity and trust matter. We combine managed IT, cybersecurity, Microsoft 365 Security, Secure AI Governance, data protection, business continuity, technology governance and project delivery in one accountable operating model.
Our Australian Head Office remains in Cottesloe, Western Australia, reflecting the company’s origins and history. It does not define the boundary of our service delivery. Clients and users are supported nationally, across Australian time zones, and internationally when travel or business operations require it.
