In 2019, the company formulated "JEIS X (Transformation)-Medium-Term Management Plan 2022-". The aim was to realize "creation of new value", and one part of that was to strengthen security measures in the supply chain. Kotaro Yonezu, a senior expert in the security response group at the company's security countermeasures office, which is responsible for the SOC function of the JR East Group, said, "Until now, the Company have provided security services to JR East. However, the JR East Group companies have implemented endpoint security measures individually.Therefore, in order to implement unified security measures as a group, the JR East Endpoint Security Service (hereafter referred to as JRE- ESS),” he explains.

With conventional security measures, forensic responses at endpoints were often manually dependent, such as the need to collect individual logs, whichwas a heavy burden. "There were times when it took from three days to a week to investigate one case. This time, the number of terminals in the entire group targeted by JRE-ESS reached a maximum of 60,000. Moreover, investigations were conducted at a reasonable frequency. I thought it would be unrealistic to continue relying on human intervention,” said Yonezu.
