Defender enhances security by using two-factor authentication to authenticate the users who request access to valuable resources within your organization. Defender uses your current identity store within Microsoft® Active Directory® to enable two-factor authentication, taking advantage of its inherent scalability and security, and eliminating the costs and time involved to set up and maintain proprietary databases. Defender’s Web-based administration and user self-service ease the implementation of two-factor authentication for both administrators and users. Defender 5.8.2 is a minor release, with enhanced features and functionality.
