When a file is attached to a field or other object, it is uploaded and stored in the platform and at that point becomes subject to monitoring by relevant policies.
Cloudlock examines the first 1000 rows and 1000 columns, and a maximum of 100,000 total cells in a single spreadsheet document. Blank cells are still counted as data and the value is "null."
Cloudlock supports scanning of pdf for content and context only when digitally created. Pdfs that are typically scanned in via a scanner which creates an "image" of the document can only be monitored for exposure and file name.
Only up to 100 of the files within a zip file are scanned and only up to 5MB TOTAL of the zip file's contents are scanned. Cloudlock supports up to 10 levles of zip file nesting (a zip within a zip within a zip). Zip files are currently only supported in DLP policies.
RFC822 Email Files
Attachments are not supported.
In the Google platform, native Google Docs do not have "filetypes" per se (they have no filename extensions, for example), but they are monitored by Cloudlock. Only objects stored in Google Drive are monitored by Cloudlock; GMail attachments that are not stored in Google Drive — like any other file or document stored outside Drive — are not monitored.
Currently, Cloudlock supports Classic and New Sites through context only policies. For example: when permissions for the site changes (i.e. editing rights) the policy will flag as an incident. Exposure is not detected through publishing, however.
Individual files larger than 15MB are not examined.
