A transport critical infrastructure project was at risk due to cascading system failures caused by poor maintenance in a high-security environment. Calexi rapidly stabilised the systems in 2 weeks, reduced the risk profile from very high to medium, recommenced commissioning, and delivered a comprehensive maintenance plan with strong stakeholder confidence.
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.
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.
When a ransomware attack exposed poor practices and failed backups, Calexi led the recovery, restored three months of data, implemented emergency fixes, and re-architected the ICT environment. The organisation avoided major reputational and financial loss while strengthening long-term resilience.
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.
Calexi led the rapid redesign and remediation of a critical Defence cyber training environment, reducing risk levels, lifting Essential Eight compliance by more than 30%, and enabling the successful completion of a multinational exercise. Our secure-by-design approach delivered measurable, sustainable improvements under tight time and compliance pressures.
