Horizon3, the AI-Native Proactive Security Company behind NodeZero®, the World’s Best AI Hacker™, today announced an alliance with Deloitte in Australia to help organisations strengthen cyber resilience through continuous, attacker-validated security assurance.

The alliance combines Horizon3’s NodeZero proactive security platform to respond to AI-accelerated vulnerabilities with Deloitte’s cyber strategy, transformation, resilience, and managed services capabilities.

Together, the two organisations will support enterprises moving beyond point-in-time assessments and theoretical risk scoring by identifying what attackers can actually exploit, prioritising the exposures that matter most, and verifying that remediation efforts are reducing real risk.

As executive teams face growing pressure from boards, regulators, customers, and insurers to demonstrate stronger cyber resilience, many organisations are still relying on fragmented security tooling and periodic testing that cannot keep pace with constant technology change. Horizon3 and Deloitte aim to help clients close that gap by combining strategic cyber leadership with continuous offensive validation across the attack surface.

Horizon3’s NodeZero proactive security platform autonomously and safely validates exploitable attack paths across modern enterprise environments. Rather than relying on theoretical risk scores or long lists of unprioritised findings, the platform helps organisations focus on the weaknesses that pose real business risk and verify that corrective action has worked.

“Organisations across Australia and New Zealand do not need more cyber noise. They need proof,” said Gareth Cox, Vice President, Sales, APJ, Horizon3. “By combining Deloitte’s strategic advisory and delivery strength with Horizon3’s ability to safely discover exposure, prioritise based on impact and remediate with clarity, we can help executive leaders make faster, better-informed security decisions, reduce risk and demonstrate measurable resilience over time.”

Through the alliance, Horizon3 and Deloitte will work together to support organisations seeking stronger confidence in the effectiveness of their cyber controls across internal infrastructure, external attack surfaces, cloud environments, identities, web applications, and hybrid estates.

The joint approach is designed to help clients understand exploitable risk in business terms, improve prioritisation across security and IT teams, support resilience and transformation programs with continuous validation, and verify that remediation efforts are working overtime.

“In an increasingly dynamic threat environment, organisations need more than periodic assurance exercises. They need continuous, evidence-based insight into where they are exposed and how to strengthen resilience. Our partnership with Horizon3 expands our ability to help clients translate attacker-perspective validation into practical action across strategy, operations, and transformation,” said Liz Douglass, Partner and Cyber Lead at Deloitte Australia.

“Horizon3 provides evidence of real exposure through attacker-perspective validation, and Deloitte helps clients translate that evidence into action, operating change, and sustained cyber resilience,” Cox added. “That is what makes this alliance meaningful for executive leaders.”
