Introduction
This document describes how Umbrella categorizes Webex meeting IP addresses as Online Meetings.
Understand Umbrella and Webex Meeting IP Addresses
Cisco Webex Meeting is a web conferencing app that uses uncategorized dynamic domains and IP addresses (CIDR ranges) that change without notice. Previously, Umbrella’s Secure Web Gateway (SWG) blocked these domains and IP addresses if customers used Web Policies that blocked Uncategorized domains and IP addresses.
To ensure SWG does not interrupt Webex Meeting services by blocking these uncategorized domains and IP addresses, Umbrella’s Policy Engine categorizes these Webex-related domains and IP addresses as Online Meetings on an ongoing basis.
This means customers are no longer required to manually manage or maintain Webex Meetings domains or IP addresses in Destination Lists or Selective Decryption Lists.
