Speak with Calexi’s GRC specialists and take control of your security obligations today.
Regulatory compliance should enable business, not hinder it. At Calexi, we help government, Defence, and critical infrastructure clients translate complex frameworks into clear, practical actions. Our Governance, Risk and Compliance (GRC) services provide expert support across PSPF, ISM, NIST, Essential Eight, and ISO 27001.
We start with where you are — conducting structured gap analyses, risk assessments, and maturity reviews. From there, we deliver tailored compliance roadmaps, policy and procedure development, and ongoing audit readiness support.
Our consultants work side by side with your teams to strengthen governance, embed defensible controls, and reduce uncertainty in high-assurance environments. Whether you need support preparing for certification, securing an Authority to Operate, or aligning with updated mandates, Calexi brings the clarity, rigour, and assurance you need.

Proven Capability in the Field
