Solution Description

OneSpan Authentication Server Framework (formerly VACMAN Controller) is an authentication platform that serves as the backend for the OneSpan Security Suite (formerly DIGIPASS). OneSpan Authentication Server Framework processes login requests to ensure that only authenticated users of the OneSpan Security Suite obtain access to protected online applications. Capable of processing large volumes of authentication requests to support high traffic web portals, the OneSpan Authentication Server Framework integrates with Entrust nShield hardware security modules (HSMs) to protect and manage the cryptographic keys used during provisioning. The combined solution ensures that cryptographic keys are never exposed on the host computer.
