What we do

Why pay more money and be tasked with managing multiple engagements, when you can find everything you need in one place?

As a 100% Australian owned and operated business, De Stefano & Co has unrivalled experience, knowledge and networks, and we are specialists in strategy and security.


Our team has decades of experience in supporting clients to achieve their growth ambitions within the Australian defence sector. We have expertise across Air, Land, Sea, Space, Cyber and Defence Estate & Infrastructure, so when we refer to ourselves as Defence and Security Experts, we're not joking.


In terms of strategy, we can provide an assessment of your business that can help to validate the defence sector opportunity quickly and cost-effectively (before you commit to entering the sector), or we can work with you to develop a long-term strategy designed to accelerate your defence sector journey. Our team can also help you develop a new cyber security strategy for your business, or review your current strategy, ensuring that it is relevant, fit-for-purpose, and offers appropriate and affordable controls and protection for your business, customers and employers.
In addition to strategy, we offer a range of protective security services, helping companies to not only meet the requirements of working with Defence, but protect their business from external threats.


These services include:

  • Defence Industry Security Program (DISP) Membership Attainment

  • DISP Ongoing Compliance Assurance (OCA™)

  • Cyber Security Services

  • Essential Eight Uplift

  • IRAP and ISM Services

  • ISO27001 Services

  • Personnel Security

  • Physical Security Uplift

  • Training and education

While clients may initially engage us for a specific service, such as attaining DISP membership, they often find value beyond their initial needs, such as strategic support for success in the defence sector, IRAP and ISM support, or DISP Ongoing Compliance Assurance (OCA™).
