HENNGE K.K. (Headquarters: Shibuya-ku, Tokyo; Representative Director and CEO: Kazuhiro Ogura) announces that it has published a new case study on the implementation of “HENNGE Tadrill” by Serverworks Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; Representative Director, President: Ryo Ooishi).
Outline of HENNGE Tadrill implementation
To streamline its targeted email attack training and improve its accuracy, Serverworks Co., Ltd., an AWS Premier Tier Services Partner and a leading company in the Japanese cloud market, adopted HENNGE Tadrill. By upgrading to the HENNGE One Pro plan, the company was able to integrate Tadrill seamlessly with its existing security infrastructure as part of the HENNGE One Cybersecurity Edition.
Since adopting the tool, Serverworks has successfully run high-quality, quarterly training sessions using Tadrill’s extensive template library. The shift to real-time analytics and a simplified, two-click submission process for suspicious emails has significantly lowered administrative workloads. Furthermore, by fostering a positive culture that rewards reporting rather than penalizing errors, the company saw a fourfold increase in employee reports, marking a significant improvement in overall security awareness.
