On 4 November 2026, I published the Integrated Security Fund Annual Report 2025-26, which sets out how the Fund has supported delivery of the Government's national security priorities over the past year. The Integrated Security Fund (ISF) is the Government's cross-government national security fund, helping to tackle the most significant threats to the United Kingdom's security at home and overseas.

The UK's security environment is becoming more contested, complex and unpredictable. The threat from state-linked actors, terrorists and organised criminals is evolving rapidly, while advances in technology create both opportunities and new risks. In response, the Government must act early, work across departmental boundaries and bring together the full range of national security expertise. The ISF enables that approach, investing more than £800 million during 2025-26 through programmes delivered across over 20 government departments and agencies to strengthen UK security, build the resilience of partners, and develop capabilities for the future.

This report demonstrates the tangible impact of that investment. At home, the Fund strengthened resilience against cyber, economic and state-based threats, helping protect critical national infrastructure, improve cyber defences across government and enhance intelligence-sharing through the Government Cyber Coordination Centre. It also supported action against cyber-enabled crime, fraud and organised criminal networks.

Overseas, the ISF supported UK interests and partners facing the most acute security challenges. This included support to Ukraine and other partners in Eastern Europe in response to Russian aggression and hostile activity by foreign states, helping to strengthen cybersecurity, counter disinformation and sustain essential services for vulnerable communities. The Fund also enhanced maritime security in the Middle East and helped partners tackle illicit finance and other threats to economic security.

The Fund is also investing in the capabilities that will underpin the UK's long-term resilience. Through programmes such as CyberFirst and TechFirst, it is developing the next generation of cyber and technology specialists, while investment in biosecurity is strengthening the UK's ability to identify and respond to emerging biological threats.

As threats continue to evolve, in 2026 and beyond, the Government is using the ISF to focus resources where they can have the greatest impact. From supporting Ukraine and strengthening cyber resilience, to addressing challenges in the Middle East and countering state-linked threats, the Fund remains a vital instrument for protecting our country’s security, prosperity and interests. Through an integrated, agile and forward-looking approach, it will continue to play an important role keeping the UK safe in an increasingly challenging world.
