Government Issues AI Call to Action for National Cyber Defence

Homeland April 27, 2026

Security Minister Dan Jarvis issued a direct call for leading AI companies and innovators to collaborate with the UK government during a keynote address at the CYBERUK conference on Wednesday 22 April 2026.

Addressing an audience of industry leaders and technical experts, the Minister characterised the development of AI-powered cyber defence as a “generational endeavour” essential for protecting the nation’s most critical networks. The initiative aims to harness autonomous systems capable of identifying and addressing vulnerabilities at a speed and scale that exceeds human capacity, responding to a threat landscape that has been fundamentally altered by advancements in frontier AI.

This strategic pivot follows data indicating that nationally significant incidents handled by the National Cyber Security Centre (NCSC) more than doubled in 2025. Hostile states and criminal actors are increasingly deploying automated AI systems to exploit network weaknesses, necessitating a robust and innovative industrial response. To support this objective, the government has confirmed an additional £90 million investment over the next three years. This funding is earmarked to bolster the cyber resilience of small and medium-sized businesses (SMEs) through existing programmes managed by the Department for Science, Innovation and Technology (DSIT) and the NCSC. For sub-contractors within the defence sector, this investment represents a clear opportunity to integrate advanced security tools into their operational frameworks.

Parallel to the technology call to action, the government is inviting UK organisations to sign a voluntary Cyber Resilience Pledge. This initiative, championed by Cyber Security Minister Baroness Lloyd, requires signatories to adopt three specific security measures: making cyber security a board-level responsibility, enrolling in the NCSC’s Early Warning service, and mandating government-backed Cyber Essentials certification throughout their respective supply chains. Baroness Lloyd has already engaged the leadership of over 180 major UK businesses to encourage adoption ahead of a formal launch later this year. For companies seeking to maintain their standing within the defence supply chain, the emphasis on Cyber Essentials certification suggests that security compliance will remain a critical prerequisite for procurement.

The Cyber Resilience Pledge and the broader AI integration strategy will form core components of the National Cyber Action Plan, which is scheduled for publication this summer. The government has consulted with more than 500 organisations during the drafting of this plan, ensuring that the final policy aligns with industrial capacity. For businesses looking to grow within the UK defence and security sectors, the Minister’s address highlights a prioritisation of sovereign AI capabilities and a shift toward proactive, automated network defence. This development provides a clear roadmap for industry partners to align their research and development with the government’s requirement for resilient, high-speed cyber infrastructure.
