Module description
Quoted from the NIST CMVP entry for this certificate.
The Tumbleweed Messaging Management System (MMS) is a suite of software products designed to allow organizations to apply content filtering and secure messaging policies on e-mail and Web traffic. All portions of the MMS use a shared set of cryptographic functionality called the MMS Security Kernel. The MMS Security Kernel exposes cryptographic application programming interface (API) calls to the other portions of the MMS.
