As of the November price list (coming soon), the TZ300s and 400s will receive access to the Capture service.  You can order it a la carte or via bundled packages such as AGSS.

This means that now the TZ line (all except the SOHO) have access to DPI SSL, Capture, and other services across the line.  This is a good discussion to have with end users who may not have yet upgraded to the newer TZ models.  Please reach out if you have any questions.
