Why Adding Cybersecurity Staff Doesn't Reduce Cyberattacks

Japan faces a shortage of approximately 110,000 cybersecurity professionals, while alert volumes increase 2.4-fold annually. Many companies attempt to address this by hiring more staff. However, the core function of SOC/CSIRT is decision-making, which does not scale proportionally with headcount. Furthermore, Japan's CISO appointment rate stands at 39.4%, lagging far behind the 96%+ rate in the US and Europe. This lack of executive ownership leaves decision-making to frontline staff, perpetuating highly dependency on specific individuals. This article examines why security breaches persist—not as a talent shortage, but as a structural flaw. Drawing on global regulatory trends like NIS2 and CIRCIA, we propose a strategic shift to design operations that realistically mitigate damage with limited personnel.
