Techniques are disclosed for hiding sensitive information from a provider of support services. In one embodiment, a first network device determines that network device information includes non-sensitive data and sensitive data. In response to the determining, the first network device generates mapping data that maps dummy information to the sensitive data. The first network device generates output data that comprises the non-sensitive data and the dummy data and sends the output data to a second network device. In other embodiments, the user may select the network parameters that are sensitive. The first network device may also receive first report data from the second network device that identifies a network problem and includes the dummy data and generate second report data by using the mapping data to replace the dummy information with the sensitive data.
