Meet the Team

When you engage Intrinsic Security, you get senior leadership directly. No hand-offs, no bait and switch.

Alex Loizou

Alex Loizou

Founder & Managing Director

"A breach doesn't end when the systems come back online. I help Boards and Executives lead through the crisis, rebuild trust, and come out genuinely more resilient."

Alex is the CISO organisations call when the stakes are highest: in the middle of a major incident, living with the aftermath of one, or when a Board wants real confidence that it is ready. He brings more than 20 years protecting some of Australia's most complex organisations, and the rare perspective of having led one through a nationally significant breach.

When to call Alex

You're in an incident

You need calm, senior leadership in the room with your team, your response partners and your Board.

You're living with the aftermath

Regulators, remediation commitments and a tired team, and the work has to keep moving once the headlines fade.

Your security leadership is stretched or vacant

An Interim or "Twin CISO" to stabilise the function and keep momentum.

Your Board wants assurance

An independent view of readiness, grounded in what real incidents actually look like.

"Battle-Tested" Experience

As CISO of Medibank during the 2022 data breach, Alex led the security response from discovery through containment, under intense regulatory, media and Board scrutiny. He then led the multi-year uplift that followed, more than doubling the security team. Few advisers have carried that accountability. Alex brings its lessons to every engagement.

How Alex Works

  • Senior and hands-on. You deal with Alex directly, not a junior team.
  • In business language. Risk, accountability, cost and customer trust, not jargon.
  • Alongside your people. He builds your team's capability, and leaves it stronger when he steps away.

Career Highlights

  • Former CISO, Medibank: Led the response to the 2022 data breach and the multi-year uplift that followed.
  • Former Head of Security (CISO-equivalent), Flybuys: Built the foundational security programme for "Australia's oldest start-up".
  • Former Acting CISO, Bupa: Led the enterprise security transformation and took the Defence Health Services project to full DISP accreditation.
