shadow networks

Shadow networks are covert or unofficial systems of relationships, communication, or influence operating alongside or beneath formal structures.

In organizations, a shadow network might be the informal connections through which decisions actually get made, bypassing official channels: The real power flows through shadow networks, not the org chart.

In security contexts, shadow networks refer to clandestine operations or hidden infrastructure—terrorist cells, smuggling routes, or untraceable communication systems.

In technology, shadow IT networks are unauthorized systems employees set up outside corporate oversight.
