Module description
Quoted from the NIST CMVP entry for this certificate.
The PostX Messaging Application Platform is a trusted email solution that is an enterprise-class platform for encrypting ad hoc emails internal and external to the customer's network. As a compliance and enterprise solution, PostX MAP provides companies the options of deployment, when and how to encrypt, and policy enforcement from 100% on the desktop, 100% at the gateway, or any combination of gateway and desktop. The PostX FIPS Cryptography Kernel is the software module that provides the basic cryptographic functionality for the Messaging Application Platform.
