Industry Challenges and Opportunities
Australia’s Defence landscape is shaped by increasing operational demands, evolving threats and complex multi-domain programs. Delivery is often delayed by layered approvals, legacy infrastructure, fragmented systems, and resourcing gaps.
Cyber resilience is now a fundamental capability, yet many programs struggle to align with the ISM, Essential Eight and DISP requirements while keeping pace with integration deadlines. Decision-makers need trusted partners who can move fast, interpret context and connect the dots across capability, security and technology.
At the same time, Defence is under pressure to accelerate digital transformation, modernise infrastructure, and enable secure interoperability between units, domains and partners. That requires not just compliance, but strategic engineering leadership that understands how Defence really works.

Our Experience in the Field
-
Cyber Tabletop Exercises
Defence required cyber exercises that reflected its unique environment and policies. Calexi delivered dynamic cyber tabletop exercises that improved response plans, created new playbooks, and uplifted staff readiness. The program trained 15 incident managers and received exceptional feedback for its realism — with lessons equally applicable to critical infrastructure operators.

Building a Sovereign Cyber Training Capability for Defence
Defence faced mounting challenges in building a skilled cyber workforce, from costly overseas training to critical skills gaps. Calexi staff designed and delivered a sovereign training program that equipped over 300 personnel, including 30+ incident responders, while saving more than $2M and creating a sustainable pipeline of skilled SOC operators.

Cyber Induction Course for Defence & Government
We designed and delivered a cyber induction course tailored for Defence and government staff, training over 300 participants across five departments. Our hands-on, practical approach bridged skill gaps, improved awareness, and built a consistent baseline of cyber security understanding across diverse audiences.
