I have used Lumension in the past and it was OK but it is too expensive. I have used Kaseya and don't like it. I have heard bad things about WSUS and it won't nativity do 3rd party applications. Shavlik is also expensive. ECORA's website is difficult to navigate and I am not interested in starting a trial simply based off that.
I downloaded a trial of GFI LANguard which looked nice but it is a standalone .NET application with no web or remote console and is crashing throwing .NET errors.
With that said, can anyone suggest me a reasonably priced/free patch management application that will do Windows and 3rd party applications, have a remote client or web interface, and that will also patch systems not joined to our network?
