I'm not sure if I completely understand your question, but WHD can integrate with a few other software solutions. Namely:
For Asset Management:
- Lansweeper
- Absolute Manage
- Casper
- SCCM
It also integrates with SolarWinds products (http://www.solarwinds.com/documentation/webhelpdesk/flarehelp/whd_12-2-0_pa_en/default.htm#cshid=HelpDeskIntegrateOrion)
- Network Config Manager
- Network & Performance Monitor
- Server & Application Monitor
Finally, for remote support, it integrates with Dameware Mini Remote Control/Dameware Remote Support.
Hopefully this answers your questions!
