GateKeeper Enterprise is a product of Untethered Labs, Inc., a U.S.-based company founded in 2015 that develops proximity-based identity and access management solutions for enterprises. The company's flagship product, GateKeeper, uses Bluetooth-based proximity detection to enable touchless, automated two-factor authentication (2FA) for PCs, VPNs, websites, desktop applications, and one-time passwords (OTPs). The core mechanism works by detecting when an authorized user's hardware token (a physical key fob or mobile device) is near a workstation, automatically unlocking it, and locking it again when the user walks away. This enables continuous authentication without requiring manual login or logout actions from employees. In addition to proximity-based authentication, GateKeeper Enterprise includes centralized password management, allowing organizations to store and auto-fill credentials without exposing them to individual users. The platform also provides comprehensive auditing and activity logging capabilities. GateKeeper targets industries with shared workstation environments or high-security requirements, including healthcare, law enforcement, manufacturing, finance, and managed service providers (MSPs/MSSPs). The solution is designed to support 24/7 shift-cycle operations common in factories and hospitals. Untethered Labs distributes GateKeeper through a global partner network and serves customers ranging from Fortune 500 corporations to specialized industrial facilities. The company holds patents on its proximity authentication technology and has received recognition on software review platforms including Capterra and G2.
