Recent BlueVoyant research found that a staggering 99% of Australian organisations experienced negative impacts from a third party or supply chain breach in the past year. This highlights how widespread these threats have become. Attackers have demonstrated that exploiting trust is often more effective than breaching networks directly.

Australian security leaders must move beyond reactive controls and checkbox assurance toward a more realistic understanding of how modern attacks unfold.

Growing urgency of third party cyber risk

Third party cyber risk has become a reality. Several Australian organisations, beleaguered by high-profile breaches, made front-page news all over the world, emphasising the importance of effective third-party cyber risk management with suppliers.

In terms of maturity of third-party risk management, only 30% of Australian organisations surveyed by BlueVoyant have established or optimised TPRM programs, significantly trailing their peers in the U.S. and Canada.

As a result, incidents last for weeks rather than hours, with recovery timelines stretching far beyond initial containment. What begins as a localised issue often escalates into broader operational disruption, forcing security teams to manage widespread outages and complex breaches. The consequences extend beyond systems and data, resulting in halted operations, financial and reputational damage, and tangible impacts on employees and suppliers alike.

Shared technologies, service providers, and business relationships have become unintentional pathways for disruption. These organisations were impacted not because their own controls failed, but because assurance stopped at the boundary of the enterprise.

As a result, organisations are increasingly being judged on how they demonstrate continuous, verifiable visibility into supplier risk. This requires moving beyond point-in-time assessments toward evidence that trust is actively monitored and maintained.

AI and Deepfakes Reshape the Threat Landscape

At the same time, the rapid adoption of AI has fundamentally changed how cyberattacks are carried out and scaled. Deepfake-enabled vendor interactions, automatically generated procurement documents and synthetic onboarding requests are no longer isolated anomalies, but recurring risks faced by organisations globally. AI has dramatically lowered the cost and complexity of impersonation, making deception faster and far more difficult to detect. In many cases, attackers no longer need to breach technical defences if they can convincingly present themselves as a trusted party.

Traditional, static assurance models are increasingly ineffective in this environment, particularly where identity, data provenance and verification are not designed for continuous validation. As AI becomes embedded across the economy, insecure systems and the data that underpins them will themselves become high-value targets. Practices such as data poisoning threaten trust, integrity and decision-making at scale, underscoring the need for security approaches that evolve as quickly as the technologies they protect.

Nation State Pressure and Blurred Threat Lines

Geopolitical instability continues to shape cyber activity in Australia. Recently, the Australian Security Intelligence Organsation (ASIO) flagged that sophisticated state-sponsored attacks are actively targeting Australian critical infrastructure assets such as airports, telecommunications networks and the energy grid.

The increasingly hybrid threat environment is accelerating the use of criminal groups as proxies, further blurring the distinction between state-backed activity and financially motivated attacks. Ransomware-as-a-Service is expected to grow in scale and severity as operators benefit from protection, coordination and, in some cases, safe haven. These actors continue to exploit vulnerabilities across global supply chains, amplifying risk for organisations well beyond their immediate networks.

A Shift Towards Proactive Readiness

Responding to these challenges require a return to fundamentals applied at ecosystem scale. Over the past year, organisations that managed disruption most effectively were those that moved beyond isolated controls and adopted a more collaborative approach to defence.

They moved away from a reliance on static assessments and periodic reviews. Instead, they invested in continuous visibility, shared intelligence, and faster remediation across operational partners. This reflects a growing recognition that resilience is no longer achieved in isolation, but through coordinated action across the environments that support day-to-day operations.

Progress is being made by organisations grounding themselves in the basics, including strong authentication, clear ownership of risk, verifiable software, and data lineage. These measures do not eliminate risk, but they materially reduce its impact and restore control in an increasingly unpredictable digital environment.

A more resilient approach to cyber defence is taking shape, grounded in shared responsibility, continuous visibility and active trust rather than periodic assurance. By working more closely with suppliers and prioritising real-time insight and verification, Australian organisations will be better positioned to support critical partners, respond decisively to disruption and limit impact when incidents occur. In today’s threat environment, resilience must be built through deliberate, ongoing action.
