The ransomware attacks on Asahi and Askul pushed Japanese incident response past what human teams can absorb on their own, and turned attention toward predicting cyberattack signs with AI before an intrusion executes. Preemptive defense reframes the problem: rather than detecting an attack already underway, read the indicators that precede it and act while there is still room to act. SimSpace is built on the same premise, exercising security teams, tools and AI models against realistic adversary behaviour inside a replica of the production environment, so the response is rehearsed before it is needed. For Japanese enterprises carrying the operational scars of 2025, the practical question is whether readiness can be measured rather than assumed.
