NCSC Touts National Scale, AI-Powered “Cyber Shield” for Defense

The UK National Cyber Security Centre (NCSC) unveiled Cyber Shield, a proposed national programme using agentic and federated AI agents to perform automated red/blue operations, national-scale vulnerability scanning, real-time information sharing, and rapid mitigations to counter AI-enabled offensive threats; the report outlines required capabilities, partnership plans with government and critical infrastructure, and delivery challenges rather than detailing any specific attack, vulnerability, or compromise.
