Actually, I was told that Server Sensor on SiteProtector (App server and DB server) was unsupported. After having numerous issues with SiteProtector, Tech Support told us to reinstall the entire thing, because of Server Sensor being on installed. Since, we've had very little problems.
This is after we were told not to harden the boxes, again by Tech Support. I have a major issue with this restraint, especially coming from a security company.
