Today is my first experience with this being integrated with Symantec. However, the top of the form shows:
PGP Evaluation Request
100-Seat Minimum for enterprise evaluations
10 seat Minimum for PGP Whole Disk Encryption Workgroup Edition evaluations
25 Seat Minimum for PGP Endpoint Evaluations
and does appear to only apply to organizations. I'll inquire about this, and post back when I know more.
