The LOCKED series is an integrated SaaS management solution provided by onetap Co., Ltd. Alongside "LOCKED DAS (Directory Auto Sync)" and "LOCKED MDM (Mobile Device Management)," it offers "LOCKED MSO," which provides integrated management of access to business systems.

LOCKED MSO is a service that provides single sign-on (SSO) to multiple SaaS/business web applications used by a company. This application, as its client-side component, is distributed to employees of contracting companies and enables secure access to business applications through multi-factor authentication combining ID and password, PIN, and biometric authentication (fingerprint/facial recognition).

■ Main Features

• Two-factor authentication using PIN codes
• Integration with biometric authentication (fingerprint/facial recognition)
• Display of each business application via WebView
• Device authentication using mTLS (client certificate)
• Lockout protection in case of consecutive authentication failures

■ Main Use Cases
• Secure access to business systems from external environments
• Enhanced information security through centralized password management for multiple SaaS applications
• Authentication and access control during teleworking
• Device authentication in BYOD environments

■ Integration with the LOCKED Series
By combining with automated account management via LOCKED DAS and business device management via LOCKED MDM, an environment that allows for end-to-end management of "people," "access," and "devices" is realized.
