We've only had a few issues with Web Help Desk, and every time we have contacted SolarWinds they have given us excellent service. We had a problem where Database backups clogged the hard drive and prevented the server from starting back up (which was a critical issue). SolarWinds contacted me in less than 15 minutes after putting in a ticket and the representative was friendly, knowledgeable, and willing to explain best practices to help prevent this from happening again.
They get a 7 because once during initial setup we were encountering problems with SSL certificates in Tomcat and the answer they provided us was a little less than satisfactory. We have our SSL certificates issued primarily as Windows PFX/PKC12, and Tomcat only accepts JKS. We were trying to get help on the conversion and SolarWinds kind of left us in a lurch. Thankfully, some people in the support forums had a solution and were able to help us out.
