Techniques for secure sharing of stage data include generating a listing in a first data exchange of a data provider. The listing includes stage data stored in a stage of the data provider and metadata associated with the stage data. A secure view of the listing is configured in a second data exchange based on posting the listing from the first data exchange to the second data exchange. The stage data is retrieved in response to a request from a client device to view the stage data received in the second data exchange. A security function is applied to the stage data to generate modified stage data. The modified stage data is stored at a second location in the stage. The metadata is updated to reference the second location in the stage.
