The free scanner checks whether your network-enabled devices might be vulnerable to attack through the UPnP protocol.

Recent research from Rapid7 revealed that around 40-50 million network-enabled devices are at risk due to vulnerabilities found in the Universal Plug and Play (UPnP) protocol. UPnP enables devices such as routers, printers, network-attached storage (NAS), media players and smart TVs to communicate with each other. Three groups of security flaws in the protocol are exposing millions of users to remote attacks that could result in the theft of sensitive information or other criminal activity such as spying.
