# Workers

We reference *Workers* within our documentation as a method of conveying the internal processes that execute your *Workflows* and *Tasks*. In general terms, you do not have to be concerned about how Workers operate and can therefore consider them essentially a 'black box'.

### Security

Workers operate within a restricted Virtual Private Cloud. Worker instances do not have public IP addresses and cannot be accessed directly from the Internet or have direct outbound access.

Task Executions are sandboxed and cannot interfere with Task Executions attached to other Workflows.
