Government announces new measures to strengthen UK defences against AI-related cyber threats

The Government has announced further measures to improve the UK’s cybersecurity as artificial intelligence becomes more widely used across public services and businesses.

Published on 12 October 2026, the plans include using advanced AI systems to identify security weaknesses and considering changes to legislation to address emerging risks.

According to the Cabinet Office, two pilot projects have already helped identify and address more than 1,000 potential vulnerabilities across government systems.

The Government now plans to expand this work to strengthen the security of public services.

Addressing new cybersecurity risks

Ministers are considering additional protections under the Cyber Security and Resilience Bill, including how serious AI-related incidents and near misses should be reported.

Work is also taking place with the National Cyber Security Centre (NCSC) and AI Security Institute to improve understanding of incidents involving autonomous AI agents.

The measures are intended to help organisations identify vulnerabilities and respond more effectively to developing threats.

What can households do?

Although the announcement focuses on national cybersecurity, individuals can also take precautions to protect their personal information and devices.

The NCSC recommends measures such as using strong, unique passwords, enabling two-step verification and keeping software updated.

Households may also find it useful to keep important telephone numbers and other essential information available offline in case internet or mobile services are temporarily disrupted.

The Government’s latest announcement is part of its longer-term approach to cybersecurity. It does not indicate that a particular cyberattack is imminent.
