The 2026 ASX 200 Security Report establishes a new baseline for Australian cyber resilience. While the average security rating has climbed to a commendable 789 (B), the data reveals a hidden volatility: scores fluctuate wildly as companies react to headline breaches rather than maintaining consistent hygiene.

This edition of the UpGuardian breaks down the benchmark across three critical dimensions—external visibility, identity hygiene, and supply chain stability—to show you exactly where your organization stands against the nation's top performers.

ASX 200 Cybersecurity Report 2026

How secure is the Australian economy? We analyzed the external attack surface of the entire ASX 200 to find out. The results reveal a highly volatile landscape: despite high average scores, 1 in 10 companies is currently compromised by an active malware infection. From the reactive jump in scores following recent incidents to the persistence of unmanaged assets, our report sets the definitive benchmark for your own cyber resilience.

The Three Dimensions of Risk: Moving Beyond the Score

The Attacker's View: Attack Surface Monitoring Guide for Security Teams

Our report found that ASX 200 security scores fluctuate wildly when new, unmanaged assets are spun up. This volatility is an attacker's window of opportunity. Discover why point-in-time assessments fail to catch these gaps and how Continuous Attack Surface Management (CASM) provides the real-time visibility you need to stabilize your posture against the benchmark.

The Dark Web View: Why Infostealer Malware Demands a New Defense Strategy

The most alarming finding in our benchmark? 10% of ASX 200 companies have an active infostealer infection on an employee device. These logs are the primary entry point for ransomware. Learn how infostealers bypass traditional endpoint protection and the specific Identity Threat Detection strategies you must adopt to neutralize compromised credentials before they are sold.

The Supply Chain View: Supply Chain Cybersecurity Strategies for Modern Business

Benchmark data shows that vendor scores jumped significantly only after major third-party breaches hit the headlines. Waiting for an incident to improve security is a dangerous game. Learn how to move from reactive cleanup to proactive vendor segmentation, ensuring your supply chain is resilient before the next headline breach occurs.

The ASX 200 benchmark proves that reactive, human-led security leads to dangerous volatility. Why? Because manual tools can no longer keep up with machine-speed attacks. Join us virtually on March 3 & 5 to see how UpGuard is moving beyond passive monitoring to Automated Defense.
