GateKeeper Enterprise is a proximity-based access management platform designed for enterprise IT environments. It combines hardware tokens, password management, and multi-factor authentication into a centrally managed system. The platform includes an on-site web server (running on IIS) with a SQL database backend, allowing organizations to manage user identities, credentials, and computer access policies from a single dashboard. Administrators can create groups, set access control policies, bulk-load users and credentials via CSV, and generate audit logs for compliance reporting. Core authentication mechanism is proximity-based: users carry a wireless token (GateKeeper Chain/key) that automatically locks a workstation when the user walks away and unlocks it when they return. This applies to Windows desktops, VPNs, websites, and desktop applications such as MES, EHR, and CAD software. The system supports domain, local, web, and OTP (one-time password) credentials. It provides automated OTP injection for two-factor authentication on websites and supports shared computer login traceability. Technical requirements include Windows Server 2012 or later and Windows 10, with deployment reported to take under 30 minutes. Remote desktop access from thin clients is also supported. The platform is positioned for compliance use cases including DFARS 252.204-7012, and is used in industries such as healthcare, manufacturing, corrections, and local government.
