Alastair
MacGibbon

Alastair MacGibbon is Australia's foremost cyber security and technology resilience leader, with more than two decades of experience shaping digital security at the highest levels of government, the private sector, and the international stage.

He is one of a very small number of individuals who have led consequential change in Australian cyber security from every vantage point — as a law enforcement officer, a regulator, a national security leader, a company builder, and a trusted strategic voice to boards and executives.

Most recently, Alastair served as Chief Strategy Officer and a member of the founding team of CyberCX, a private equity-backed cyber security company that grew to more than 1,400 people across Australia, New Zealand, the United States, and the United Kingdom, making it the largest cyber security company in the region. The business was subsequently acquired by Accenture.

Prior to this, Alastair held a series of senior national security, regulatory and law enforcement roles including:

- Establishing and leading the Australian Cyber Security Centre (ACSC) as a Deputy Director General of the Australian Signals Directorate and concurrently the National Cyber Security Adviser as a Deputy Secretary in the newly-established Department of Home Affairs;

- Special Adviser to the Prime Minister on Cyber Security as a Deputy Secretary in the Department of the Prime Minister and Cabinet;

- Australia's inaugural eSafety Commissioner, where he created and led from the ground up a world-leading online safety regulatory framework that has since become a model for jurisdictions internationally; and

- A 15 year career as a Federal Agent with the Australian Federal Police which included a diplomatic posting to the Australian Embassy in Washington DC, a secondment as an investigator to the Wood Royal Commission into Police Corruption, and a stint at the Office of National Assessments (now ONI), he founded the Australian High Tech Crime Centre (AHTCC), Australia's first dedicated national capability to investigate and disrupt cyber crime.

Across all of these roles, Alastair has been a consistent and trusted voice on cyber security and technology resilience as a business and governance imperative, not merely a technology problem.

He has briefed Prime Ministers, Cabinet Ministers, senior public servants, boards, and chief executives.

This includes working with like-minded governments in the Pacific, Asia and beyond for decades.

He regularly leads the national debate on cyber risk, digital resilience, and the obligations that fall to leadership in an era of persistent threat. His ability to translate highly complex technical risk into clear, actionable board-level and executive decisions is a defining feature of his career.

Today, Alastair is an independent adviser and strategic partner to boards, executive teams, and investors navigating decisions at the intersection of cyber security, technology risk, and organisational resilience. He brings practitioner depth, national-level policy experience, and private sector commercial acumen.
