Skip to main content ITCSAU - Advising Sovereignty in a Digital Age

Founder & Managing Director

Marc Mendis

Advising Australia's most consequential organisations at the intersection of sovereign technology, artificial intelligence, and critical infrastructure resilience.

Background

Marc Mendis brings 15+ years of experience in enterprise technology, cybersecurity strategy, and digital infrastructure to his role as Founder and Managing Director of ITCSAU. His career spans the full arc of Australia's digital transformation, from early enterprise architecture engagements through to the current convergence of artificial intelligence, energy systems, and national sovereignty.

His advisory practice focuses on the strategic challenges that emerge when technology becomes critical infrastructure. This includes sovereign compute architecture for government and defence, AI governance frameworks for regulated industries, and the complex energy demands of next-generation data centres. Marc's work is grounded in the conviction that Australia's digital future requires deliberate architectural choices, not passive adoption of foreign platforms.

Marc holds deep expertise across the Australian regulatory landscape, including Essential Eight maturity modelling, SOCI Act compliance frameworks, and IRAP assessment methodologies. He advises boards and executive leadership teams on translating these requirements from compliance obligations into genuine organisational capability, ensuring that security posture and strategic ambition remain aligned.
