Secure and reliable content disarm and reconstruction cloud service

A file Content Disarm and Reconstruction (CDR) system comprising:

• a physical computer;
• a disarm environment hosted by the physical computer comprising disarm sandboxes to transform a file;
• a reconstruct environment;
• and
• a controller to classify a file content of a file as a filetype, to provide the file and the filetype to a selected disarm sandbox of the disarm sandboxes for transformation, to receive one or more disarmed files from the selected disarm sandbox, to provide the one or more disarmed files to the reconstruct environment, and to receive a reconstructed file from the reconstruct environment,
• wherein the disarm environment, the reconstruct environment and the controller are isolated and separated from one another by hardware, and
• the selected disarm sandbox transforms the file by deconstructing the file into primitive chunks, by skipping a potentially invalid, malicious or unauthorized primitive chunk of the primitive chunks, by saving a text file comprising an object type and associated properties for each known primitive chunk, and by saving graphics content in the file in a graphics file per a basic image file format.
