Abstract: A computing device, such as a server, has a sealed housing and runs one or more data extraction agents. In some embodiments, the computing device includes one or more processors and memory located inside the sealed housing, the memory stores instructions that when executed by the one or more processors causes the one or more processors to: authenticate with a data recipient system using a prestored security engine and using a shared registration secret uniquely associating the computing device with the data recipient system; retrieve an extraction job specification from an extraction job specification repository associated with the data recipient system; and using the extraction job specification, communicate to one or more client computing devices associated with a client system to extract data records from one or more data stores of the client system. Related methods are also disclosed.
