    Standard

    Glasswall extrapolates the file at a high level (e.g., container level), and then validates these components against a subset of selected rules from the file vendor specification. For example, Glasswall may validate attributes of a container and ensure that the streams are of the correct size, running order, and encoding in relation to the container metadata. However, the contents of these streams are not further inspected, validated, or cleansed.

    Note: Constellations does not support binary executable files due to the standard protection level being applied by the Glasswall engine. This precautionary measure ensures that potentially risky binary files do not make their way to the destination.

    Zip & Archive Support

    Archive formats and file types are first identified using a structural check and then decompressed. 

    Depending on the format of extracted file types, the contents of the archive are processed and a brand-new archive with the secured content is created.
