Technology, Threats and the Future of UK National Security

The UK’s national security landscape is changing at unprecedented speed. Technology has become the primary arena in which threats emerge, evolve, and are countered. From AI enabled cyberattacks to autonomous systems and digitally‑driven criminal networks, the pace of technological change is reshaping the strategic environment. Across government and industry, I am seeing a growing consensus: the UK’s future security will depend on our ability to harness technology as effectively as those who seek to undermine it. 

AI: the new strategic high ground 

Artificial Intelligence is now central to the national security mission. The National Cyber Security Centre (NCSC) has highlighted how AI is accelerating the sophistication of cyberattacks, enabling hostile actors to automate reconnaissance, craft highly convincing phishing campaigns, and exploit vulnerabilities at scale. This is not a future risk, it is a present reality. 
At BAE Systems Digital Intelligence, we see this shift every day in our work with UK defence and intelligence customers. AI is not simply amplifying existing threats; it is changing their nature. The challenge for customers is twofold: countering adversaries who are weaponising AI, while integrating AI responsibly and securely into national security operations. 
Our collaborations reflect this commitment. Through working with organisations such as Oxford Dynamics, we are advancing the delivery of AI‑driven analytics across air, land, sea, space, and cyber domains; supporting decision‑makers with trusted, explainable insights and illustrating how deeply AI is becoming embedded in defence capability. 
AI is now a contested domain. Maintaining advantage requires continuous innovation, robust safeguards, and close collaboration between government, academia and industry. 

Cybersecurity as national infrastructure 

Cybersecurity has become the backbone of national resilience. The National Cyber Strategy emphasised whole‑of‑government cyber readiness, improved vulnerability management, and the protection of critical national infrastructure. 
At BAE Systems Digital Intelligence, we are focused on integrating diverse data sources to detect threats earlier and respond more effectively. Our annual Cyber Forum, which brings together leaders from government, academia, and industry, reinforces a core principle: no single organisation can defend against today’s agile, well‑resourced adversaries alone. 
In an era where cyber operations can disrupt energy grids, supply chains, and democratic processes, cybersecurity is national security. 

Geopolitical instability and hybrid threats 

The global security environment is increasingly volatile. The National Crime Agency (NCA)’s National Strategic Assessment 2026 highlights how geopolitical instability is enabling new forms of serious and organised crime, while parliamentary committees warn of rising foreign interference and espionage. 
Hybrid threats, which can combine cyber operations, disinformation, criminal activity, and physical disruption, demand integrated, intelligence‑led responses. The boundaries between domestic and international security, and between criminal and state‑sponsored activity, are becoming increasingly blurred. 

Emerging technologies reshaping defence 

Autonomous systems, advanced sensors, and digital platforms are redefining defence capability. The Integrated Review Refresh from 2023 underscored the importance of dual‑use technologies, supply‑chain resilience, and rapid adoption of AI‑enabled systems. 
Our work with the Home Office, processing data from hundreds of millions of passenger journeys and freight movements, demonstrates how advanced analytics are already transforming border security. 
These technologies offer strategic advantage, but we must always remain aware of potential new vulnerabilities. Ensuring technology is secure, interoperable, and ethically deployed is a core national security consideration. 

The convergence of criminal markets 

Digital tools are enabling criminal networks to diversify and collaborate in new ways. The NCA identifies criminal‑market convergence as a defining trend, with fraud, cybercrime, and illicit trade increasingly intertwined. 
Criminal groups are exploiting the same technologies used by legitimate organisations – AI, automation, and global connectivity – to scale their operations and evade detection. This demands more integrated intelligence, stronger partnerships, and a whole‑system approach to disruption. 

Looking ahead 

Technology is reshaping UK national security faster than policy, doctrine, or public understanding can keep pace. The challenge is significant, but so is the opportunity. If the UK can harness emerging technologies responsibly and collaboratively, it will strengthen national resilience and help shape the future of global security. 
At BAE Systems Digital Intelligence, our mission is clear: to help protect the UK by delivering trusted, data‑driven, and technologically advanced national security capabilities. Working alongside government, industry, and academia, we remain committed to ensuring the UK stays ahead in an increasingly contested and complex world.
