Ireland’s Cybersecurity ‘Race’: AI’s Unpredictable Impact on National Security
Ireland is facing a “generational change” in its digital security landscape as the rise of artificial intelligence (AI) fundamentally alters the nature of cyber threats. During a critical meeting of the Joint Committee on Artificial Intelligence on April 14, 2026, top security officials warned that the intersection of AI, defence, and cybersecurity is now one of the most pressing challenges facing the state.
The hearing, chaired by Deputy Malcolm Byrne, brought together leaders from the National Cyber Security Centre (NCSC), the Department of Defence, and the Irish Defence Forces to address the accelerating capabilities of both state and non-state threat actors.
An ‘Inherently Unpredictable’ Threat Landscape
Dr. Richard Browne, Director of the National Cyber Security Centre (NCSC), told the committee that the implications of AI for cybersecurity are “both vast and inherently unpredictable.” Browne emphasized that the technical frontier is advancing weekly, placing Ireland in a high-stakes race to adapt its defences.
According to Browne, threat actors are already heavy users of AI tools, which allow for the “greater automation of attack processes.” He described AI as a revolution that will affect every digital technology that preceded it, making the management of cyber-related risks to society far more dynamic and complex.
Military Adaptation and Generative AI
The integration of AI into national defence is no longer theoretical but a strategic necessity. Brigadier General Mark Staunton, Commander of the Defence Forces Joint Cyber Defence Command, informed the committee that his unit remains proactive in evaluating how to appropriately incorporate AI into military capabilities.
Complementing this military perspective, Jason Kearney, Director of Emergency Operations and Infrastructure Oversight in the Department of Defence, highlighted the dual nature of the technology. Kearney stated that while generative AI creates significant new opportunities, it also introduces challenges that are “broader and more complex than anything we have previously encountered.”
Geopolitical Risks and Lessons from the Past
The committee highlighted that Ireland remains a target for sophisticated cyberattacks. Deputy Malcolm Byrne specifically identified risks emanating from non-state actors and foreign states, notably Russia, China, and Iran.
The urgency of these measures is underscored by previous failures. Byrne cited the 2021 HSE cyberattack as a stark example of the devastating impact that occurs when robust cybersecurity measures are not in place. He warned that if future attacks are AI-enabled, the challenges to public services will be even greater due to the rapid pace of technological development.
Key Takeaways: AI and Irish National Security
- Automation of Attacks: AI allows foreign adversaries to automate cyberattacks, increasing the scale and speed of threats.
- The ‘AI Race’: Security officials describe a constant race to keep pace with the “leaping” technical frontier of AI tools used by hackers.
- Military Integration: The Irish Defence Forces are actively considering the incorporation of AI into their military capabilities to maintain security.
- High-Risk Actors: Russia, China, and Iran are identified as primary state-level threats to Ireland’s digital infrastructure.
Looking Ahead
As the Oireachtas Committee on Artificial Intelligence continues its series of meetings on defence and security, the focus remains on bridging the gap between rapid technological advancement and legislative or operational readiness. The consensus among officials is clear: the “unpredictable” nature of AI requires a dynamic, proactive approach to protect Ireland’s public services and national sovereignty from increasingly automated threats.
