Is UPnP chromecast a necessary security measure?

I'd like to use Chromecast on our office network. Doing so requires enabling UPnP (Universal Plug and Play).

A quick search turns up statements like this: The US Department of Homeland Security is urging everyone to disable the common networking Universal Plug and Play (UPnP) protocol...UPnP has been, is now, and will always be a security nightmare of a protocol. http://www.zdnet.com/article/how-to-fix-the-upnp-security-holes/ Is it true that UPnP is fundamentally and irreversably flawed? Are there any mitigating circumstances in which it isn't "a security nightmare"? Is there any way to use Chromecast without compromising security?
