HENNGE K.K. (Headquarters: Shibuya-ku, Tokyo; Representative Director and CEO: Kazuhiro Ogura) announces publication of a new case study on the implementation of “HENNGE One” by the Yamanashi Chuo Bank, Ltd. (Headquarters: Kofu-shi, Yamanashi; President: Yoshiaki Furuya).
Outline of HENNGE One Pro implementation
Operating under the purpose “Open Up a Bright Future from Yamanashi” as the sole regional bank based in Yamanashi Prefecture, The Yamanashi Chuo Bank, Ltd. adopted HENNGE One during its IT infrastructure migration to Microsoft 365. Key reasons for choosing HENNGE One included its seamless integration with Microsoft 365, as well as its scalability to manage targeted email attack training and threat protection for Microsoft 365 on a single unified security platform.
By utilizing HENNGE One as its core email security infrastructure, the bank maintained its supervisor approval process for outbound external emails while eliminating password-protected (encrypted) ZIP attachments. In addition, by in-sourcing targeted email attack training and enabling safe, convenient file sharing, the bank achieved the high security standards required of a financial institution alongside improved operational efficiency.
