Australian Firms Unify Cybersecurity as Threats Increase

Enterprises build advanced, cloud-based security architectures as AI makes both attacks and defenses more effective and efficient, ISG Provider Lens^® report says

SYDNEY--(BUSINESS WIRE)-- A growing number of enterprises in Australia are taking a centralized, cloud-based approach to cybersecurity amid rising threats, many of which involve AI, according to a new research report published today by Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm.

The 2025 ISG Provider Lens^® Cybersecurity — Services and Solutions report for Australia finds that Australian organizations face increasingly sophisticated, AI-powered attacks but are hobbled in defending against them by overlapping cybersecurity solutions that fail to share information with each other. Many companies are simplifying their defenses while adopting AI tools for more effective, efficient security.

“While AI is starting to significantly change the way Australian companies operate, in the wrong hands, it can also cause serious harm,” said Michael Gale, partner and regional leader, ISG Asia Pacific. “Fortunately, service and solution providers are using AI to help enterprises detect and prevent attacks.”

Use of AI can expose organizations to malicious interference in the training of AI models, which can make models less reliable or cause them to produce biased or inaccurate predictions, ISG says. Organizations in Australia are also increasingly concerned about a growing category of threats enabled by generative AI, especially through voice cloning and the creation of deepfake images, videos and audio clips. These can be used to steal money, extract sensitive information and damage reputations. Narrative attacks use these methods to create false or misleading narratives, including spreading misinformation about vaccines or elections.

In response, Australian companies are strengthening identity protection and integrating AI into security operations, the report says. GenAI and agentic AI are increasing the efficiency and productivity of security teams and helping enterprises address the shortage of cybersecurity skills.

Cloud security has emerged as a top priority for cybersecurity leaders in Australia after companies rapidly migrated to the cloud to enable remote work during the COVID-19 pandemic, ISG says. Security was often a secondary consideration in these transitions, so organizations kept traditional perimeter-based cybersecurity architectures in place. Now, many are taking a more distributed approach, focusing on endpoints and preventing cloud misconfigurations and vulnerabilities.

Enterprises in Australia have often ended up with multiple tools for endpoint detection and response (EDR) and identity and access management (IAM), along with many dashboards that lack integration, the report says. Increasingly, cybersecurity leaders in these companies are narrowing down their defensive systems to one or a few cloud-based platforms.

“Australian companies are trying to do more with less in cybersecurity,” said Andrew Milroy, lead author of the report. “Reducing complexity, minimizing overlaps and engaging with a core set of qualified partners helps to mitigate risk.”

The report also examines other cybersecurity trends in Australia, including rising expectations for data retention and the recent extension of national cybersecurity requirements to more industries.
