Techniques that facilitate multiple sentinels for securing communications are provided. In one example, a system communicates with at least one multi-purpose device configured to communicate with one or more sources, at least one computing device configured to communicate with a defined source that is different than the one or more sources, and at least one security sentinel that manages one or more security processes for a communication network associated with the at least one multi-purpose device and the at least one computing device. The system also manages one or more other security processes for the communication network associated with the at least one multi-purpose device and the at least one computing device.
