The system Categories in the Cato Management Application (Assets > Categories > System Categories) are managed by Cato networks for ease of use. However, what exactly is the difference between the content in the Uncategorized and Undefined system Categories?
Uncategorized - web content or domains that does not fit in an existing system Category. Often this follows standard practices that the specific web content is considered as uncategorized by different security vendors.
Undefined - web content or domains that temporarily the Cato Cloud is unable to define. There are numerous reasons that can cause traffic to be Undefined, for example a Microsoft Teams domain can be identified as Chat & IM and then later temporarily identified as Undefined.
