Fujitsu unveils AI-era cyber defense lifecycle strategy

Fujitsu's new strategy responds to two shifts: AI-driven attacks that are faster and more precise, and IT environments that now span clouds, external data links, and entire supply chains. The company argues that traditional security operations—focused on preventing intrusion or detecting it after the fact—are no longer enough to keep corporate defense capabilities up to date. Therefore, it redefines cyber defense as a continuous lifecycle from strategic planning through improvement, supported by models that clarify what to protect, how to defend, and who is responsible.

The initiative combines organizational and technical elements. The Nerve Center acts as the core, consolidating knowledge from Fujitsu's own experience as a "customer zero," customer feedback, and external technology from startups and partners. The Cyber Nerve System will provide data-driven visibility to guide defense activities and promote autonomous action at the operational level. The strategy also includes developing specialized talent through Fujitsu's security master program, feeding practical knowledge back into training. Going forward, Fujitsu plans to roll out consulting, system building, and AI-powered defense services gradually, potentially including contributions to Project YATA-Shield, a Japanese government initiative announced in May 2026 to counter high-speed, large-scale AI attacks.
