Systems, methods, and devices for performing a layer-2 scan of one or more communication networks to collect detailed information regarding the components/devices attached to the networks at a particular location (e.g., metropolitan area, city, university campus, building, floor within a building, etc.), and using the collected detailed information to generate a device profile for each of the devices attached to the one or more communication networks at the particular location. A server computing device may use the generated device profiles to perform inventory control operations, wireless vendor integration operations and/or security operations. For example, the server may use the device profiles to determine whether a component/device attached to any of the networks is non-benign (e.g., improperly configured, running malware, operated by hacker, spoofing a server, dropping packets, etc.), and initiate a reactive or mitigating action (e.g., quarantine the device, etc.).
