To perform data discovery, Prisma SaaS gets metadata for all
your files and folders on the application. Metadata includes file
properties and attributes, and application-level metadata such as
file owner, email recipients, and collaborators. For certain
apps with structured data such as Salesforce, and messaging apps such
as Slack, Facebook Workplace, and email apps, Prisma SaaS scans
both structured and unstructured data. All files such
as attachments that are unstructured, the files are scanned and
the metadata is always stored. Even though Prisma SaaS scans structured
data, it does not store metadata for every field and message unless
the field or message has some content that matches a data pattern
defined on Prisma SaaS. This is done to minimize the privacy risk
by storing all of your metadata.
