Internal Control DX SaaS 'smoove J-SOX' Launches SSO (Single Sign-On) and MFA (Multi-Factor Authentication) Features

WARC Inc. (Headquarters: Shinagawa-ku, Tokyo, Representative Director & CEO: Akihiko Yamamoto, hereinafter "WARC") has launched the "SSO (Single Sign-On) Feature" and "MFA (Multi-Factor Authentication) Feature" for its internal control DX SaaS "smoove J-SOX" in March 2026. This update realizes enhanced security and labor-saving in account management and operations.

Background of Providing SSO and MFA Features

### The Need for Streamlined Authentication and Account Management in Internal Control Tools As the use of cloud services expands, there are increasing instances where many companies utilize multiple systems and tools. As a result, the practice of managing IDs and passwords for each individual system has become common, increasing the burden on users and administrative departments, while also making it a challenge to address security risks that rely solely on password authentication.

In the realm of internal control and internal auditing, authentication methods and the structure/operational rules of account management have become critical items that require explanation from a security perspective.

Given this background, smoove J-SOX has started offering "SSO" to centralize authentication and account management, and "MFA" to prevent unauthorized logins. These features will assist in saving labor for account management and operations while enhancing security.

### Providing SSO Login Integrated with Existing Authentication Providers smoove J-SOX now supports SSO integration with major authentication providers. With this new feature, users can log in securely using a single authentication provider, eliminating the need to manage dedicated IDs and passwords.

Furthermore, when an employee leaves the company, administrators simply need to deactivate the account on the authentication provider side to immediately block access to the SSO-integrated smoove J-SOX, thereby reducing the operational burden related to access rights.

### Supported Authentication Protocols and Providers Authentication providers supporting SAML 2.0
