Who are We
In 1997, Mark O’Malley incorporated what is now known as Delta Sierra Consulting / DSC after his mechanical engineering studies. Today, DSC is an Australian-owned cybersecurity, managed IT and Secure AI governance firm supporting Family Offices, their private enterprises and not-for-profit clients across the Asia-Pacific region.
DSC works with clients where privacy, resilience, continuity and trust matter. Our role is to help leadership teams protect sensitive information, strengthen cyber resilience, manage technology risk and adopt AI securely.
We remain deliberately Australian-owned and locally accountable. Our clients value working with Australian-based personnel who understand their operating environment, privacy expectations, governance responsibilities and long-term technology needs.
Mark O’Malley — Founder & Managing Director
Mark O’Malley is the Founder & Managing Director of DSC / Delta Sierra Consulting. He advises Family Offices, their private enterprises and not-for-profit clients on cybersecurity, managed IT, Microsoft 365 security, Secure AI adoption, Shadow AI risk, data protection, business continuity and practical technology governance.
Mark is also co-founder of the Family Office Scaffolding Forum, a private peer-led forum focused on the non-investment infrastructure (scaffolding) that supports Family Offices — including people, processes, systems, advisers, governance, cybersecurity, privacy, technology risk and Secure AI.
Based in Perth, Western Australia, Mark is married to Pip van Helvoort and is a father of two. His work is grounded in helping families, executives and organisations protect what matters while making better technology decisions.
Our Approach
Where possible, DSC minimise competitive vendor offerings within the DSC Partner portfolio, and always take a “business first”, and “vendor agnostic” approach towards our customers solutions; as opposed proposing a solution just because DSC is partnered with the vendor. This way the most suitable solution is recommended for the customers’ requirements, as opposed to the wrong solution presented because it is maximising the salespersons commission payment for the quarter. DSC account management personnel are not bonused in this manner as we have found it drives poor behaviour and sub-optimal outcomes for DSC customers.
Our Model
In 2007, DSC created the first version of its Corporate Managed Services offering, and as each client provides input and feedback, DSC evolves and optimises the model, offering and pricing with each updated version.
Ultimately this model and approach allows DSC customers to budget their monthly support costs, and have the ability to predict the cost of IT for new locations, assets, staff increases/decreases or closing locations etc. (as we have seen recently during some of our customers responses to the COVID-19 pandemic) as part of their organisational planning and Board strategy.
Our Staff
Our Managed Services are only as good as the DSC staff that deliver it. DSC’s senior staff have each been with the company for almost a decade, and have global backgrounds and significant technical and business skillsets as a result. This stability of key personnel, when coupled with the maturity of the Managed Services practice, are the ingredients that provide DSC customers with the excellent service delivery that they attest to during client reference checking and referrals.
