mRemoteNG

Great for gathering multiple remote server and device access protocols into a single application where they can be organized grouped and easily searched for. You can use the tree hierarchy to group servers\devices or search quickly to find what you want. It also allows you to add external applications as an object to connect to so web page-based iDRAc, for example, can be managed in the same place as the native desktop access of the same server—very convenient. Sadly, the main downside to this app is its lack of active development which is a shame as it is the most convenient of multi-protocol remote server access tools I have come across.

Well suited to environments where IT staff need to access multiple servers/systems at the same time, cutting down on time wasted opening multiple windows.

Not so useful for users that only need to access one system remotely, as most of its functions are largely unused in that case.
