HENNGE K.K. (Headquarters: Shibuya-ku, Tokyo; Representative Director and CEO: Kazuhiro Ogura) announces that its cloud security service “HENNGE One,” which mitigates security risks associated with SaaS usage and promotes technology adoption, now supports single sign-on to “Kasanare,” a generative AI software for enterprises provided by Kasanare Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Kyoichi Yasuda).
Generative AI has seen remarkable progress and widespread adoption in various business operations. However, its practical utilization demands specialized knowledge, technical expertise, and ongoing refinement to align with a company’s specific tasks, challenges, and compliance standards. This presents numerous hurdles before it can be effectively implemented. Solutions like Kasanare, which offer customization for individual companies and departments, enable efficient and highly accurate use of generative AI, thereby supporting business growth.
The integration of HENNGE One and Kasanare enables the companies employing HENNGE One to use a single sign-on to Kasanare. They no longer have to manage complicated multiple IDs and passwords. Furthermore, HENNGE One’s access control features, such as IP Control and multi-factor authentication like device certificate, contribute to safer usage of Kasanare, reducing the risks of unauthorized access.
HENNGE will expand the range of SaaS that integrates with HENNGE One to support companies’ convenient and secure adoption of SaaS.
