I have been working with Guardium for 5 years, but I had not heard of Vormetric. So, I will not be able to help.
Something I can report is from the IBM website:
" IBM Security Guardium Data Encryption runs on a variety of Microsoft Windows, UNIX, and Linux platforms. It requires prerequisite software available from Vormetric, Inc. Visit the Vormetric website for information.
For additional information, refer to the Software requirements section. Vormetric is not affiliated or associated with IBM. Vormetric software products and licenses are subject to change in accordance with the policies and procedures of Vormetric. "
