Why shouldn't I use UPnP in a large or corporate environment?

UPnP is a very helpful protocol in getting devices to communicate with each other in a network without having to manually configure them. However, it is only meant for use in home networks or SOHO networks. It is not appropriate for use in a large or corporate network, and there are several reasons for this:

  • UPnP uses multicast for device discovery. This multicast foundation makes it chatty, consuming too many network resources on networks with a large population of devices​.
  • UPnP's simplified access controls don't map well to complex environments​.
  • It does not provide a uniform configuration syntax.
  • There is no authentication with UPnP.
