Cyber Shield: The path to an agentic AI future for cyber defence
Summary
The UK government is developing Cyber Shield, a national defense program that uses agentic AI (AI systems that can independently identify and fix problems) to protect critical infrastructure from cyber attacks at machine speed. The program addresses both existing vulnerabilities like outdated systems and emerging threats where AI is helping attackers conduct reconnaissance and discover weaknesses much faster than before, sometimes reducing response time from weeks to minutes.
Solution / Mitigation
Organizations should take urgent tactical action by: rapidly patching vulnerabilities, reducing reliance on legacy systems, adopting secure-by-design technologies, using agentic AI to identify exposed vulnerabilities autonomously as a defensive measure, using AI to detect and contain security incidents, and working to address the challenge of safely automating mitigation responses.
