HENNGE One Now Supports SSO to an Alternative Legal Service Provider, “Cloud Legal”

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 “Cloud Legal,” an alternative legal service (ALSP) provided by a23s (Headquarters: Chuo-ku, Tokyo; CEO, Attorney-at-law of Japan/New York State, the U.S.: Yasufumi Sakiji).

In recent years, companies have faced an increasingly diverse and complex array of laws and ethical codes, resulting in a rise in daily legal tasks. To address shortages in legal and compliance personnel or when highly specialized knowledge is required, the use of cost-effective Alternative Legal Service Providers (ALSPs) is expanding in Japan to support companies with legal and labor matters.

Cloud Legal is a next-generation ALSP, an enterprise legal outsourcing service that integrates generative AI with a scaled system of legal and specialized professionals.

The integration of HENNGE One andCloud Legal enables HENNGE One users to use a single sign-on to Cloud Legal. 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 Cloud Legal, 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.
