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 “Kaikeijimusyo-Cloud,” a cloud-based accounting system for professionals provided by Sorimachi (Headquarters: Chiyoda-ku, Tokyo; Chief Executive Officer: Sorimachi Hideki).
Automation of accounting for small and medium-sized enterprises (SMEs) in Japan has stagnated due to resource constraints. SMEs often rely on bookkeeping services, outsourcing the maintenance of journal entries and ledgers. Kaikeijimusyo-Cloud is a cloud-based accounting system designed specifically for accounting firms to address such a situation. The system automates the confirmation of transaction details and journal entries by integrating various tools, delivering significant value, including visualizing productivity and enabling management analysis for client companies.
The integration of HENNGE One and Accounting Firms Cloud enables HENNGE One users to use a single sign-on to Accounting Firms Cloud. 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 Accounting Firms Cloud, 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.
