Impact

By ensuring that your IoT Hub is not public, you can help protect your data from unauthorized access or tampering. Public IoT Hubs are accessible over the internet, which can make them vulnerable to external threats such as hackers or malware. By making it private, you can help ensure that only authorized users can access the data.
