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 “Helpfeel Cosense,” a knowledge enablement tool provided by Helpfeel Inc.

Organizing and disseminating internal knowledge is vital for leveraging AI and boosting workplace productivity. Helpfeel Cosense enables seamless knowledge sharing and storage by fostering a culture of documentation.

The integration of HENNGE One and Helpfeel Cosense enables HENNGE One users to use a single sign-on to Helpfeel Cosense. 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 Helpfeel Cosense, reducing the risks of unauthorized access.
HENNGE will expand the range of SaaS that integrates with HENNGE One to support companies with IT applications and foster innovation.
