2025 Nexon Cyber Security Report: Exposing Australia’s Hidden Vulnerabilities

The 2025 Nexon Cyber Security Report delivers an unfiltered look at how Australian organisations are really being compromised—and what can be done to stop it. Drawing on insights from 126 penetration tests across 30+ industries between July 2024 and June 2025, the report reveals the most common weaknesses leaving businesses exposed to attack.

Far from sophisticated nation-state operations, most breaches stem from basic, preventable control failures. Weak password practices, missing multi-factor authentication, outdated legacy systems, poor privilege management, and human error remain the top culprits behind security incidents.

Nexon’s research distils these findings into seven key insights that show where organisations are most vulnerable—and where security improvements will have the greatest impact. With cyber threats evolving rapidly, understanding and addressing these weaknesses is vital for resilience.
