Supported File Formats

Skyhigh CASB can analyze the contents of files that pass from user devices to the cloud. We support specific formats for content analysis and a broader set of file formats for signature-based file type detection.

Formats can be analyzed in one or both of the following ways:

• Text Extraction. We extract text content from the associated file type. Many of the file types we support are basically containers that can be opened only through their native application (try opening a PDF document through TextEdit). If this is selected, we support text extraction of content for that type.
• Metadata. Skyhigh CASB can extract metadata from file types with checkmarks.

For File Type Detection, see Supported File Formats for File Type Detection.
