Understanding Shadow IoT

Shadow IoT refers to Internet of Things devices that are connected to an organization's network without the knowledge, approval, or oversight of its IT or security teams. Examples range from employee-owned smart speakers and fitness trackers to unauthorized cameras, sensors, and smart appliances, each of which can introduce unmonitored entry points and expand the attack surface. Because these devices often ship with weak default credentials and infrequent patching, shadow IoT poses significant risks that are difficult to manage without continuous network discovery and asset visibility.
