"Resurrection from a Cyberattack: The Trajectory of Decisions to Protect the Company"
"We'll be fine" — such complacency can lead to situations that shake the very foundation of a business.
In September 2024, a ransomware attack brought our core systems to a complete halt. Chairman Tatsushiro himself will reveal the behind-the-scenes management decisions made from the occurrence of the damage to recovery.
He will share the "reality of decision-making" based on his actual experience, explaining how he mobilized the organization and led it to business continuity. He will also openly discuss the lessons that should be prepared for in peacetime, which only someone who has been in the depths of despair can tell.
