Balancing Reduced Operational Load of Targeted Email Training and Transforming Employee Cybersecurity Awareness

HENNGE Corporation (Headquarters: Shibuya-ku, Tokyo; Representative Director and President: Kazuhiro Ogura) has released a case study on the implementation of "HENNGE Tadrill" by Serverworks Corporation (Headquarters: Shinjuku-ku, Tokyo; Representative Director and President: Ryo Oishi).

Overview of HENNGE Tadrill Implementation

Serverworks Corporation, a leading cloud market player in Japan as an AWS Premier Tier Services Partner, implemented HENNGE Tadrill with the aim of reducing the operational burden and improving the accuracy of targeted attack email training. Tadrill is a targeted attack email training function included in "HENNGE One Cybersecurity Edition." The decision to adopt Tadrill was driven by the ability to comprehensively implement it alongside other security functions by migrating to the HENNGE One Pro plan.

Following implementation, high-quality training has been conducted quarterly using Tadrill's extensive templates. Operational load has been eliminated through real-time visualization of results and a two-click reporting function. Furthermore, by praising reports rather than reprimanding mistakes, the number of employee reports has quadrupled. This has fostered a culture of proactively reporting risks, leading to a transformation in company-wide security awareness.

About HENNGE One

HENNGE One is the No. 1 cloud security service in Japan (※) that enhances organizational productivity. While the utilization of the latest technologies, including SaaS, is essential for improving productivity, various challenges exist, such as building zero-trust security.

HENNGE One offers three editions to solve these challenges: "Identity Edition" for protecting multiple system IDs collectively and enabling efficient work styles; "DLP Edition" for preventing unintentional leakage of data scattered across an organization; and "Cybersecurity Edition" for protecting against cyberattacks from all directions, including people, processes, and devices.

It realizes zero trust by lowering the hurdles for implementation and operation with security services, and liberates technology.
