We need to secure Data Loss Prevention (DLP) over WebEx and have great capability to do so with the WebEx application. We are looking into a means of doing this with WebEx participants who join strictly via the browser, but we cannot seem to do this without breaking their experience. We're thinking it may be simpler to just have company policy state that employees must join WebEx meetings via the application only.
Having said that, are there specific domains, IP addresses, or anything else that are exclusive to the browser-only version of WebEx that we could block? I could not find anything on the whitelist documentation that stated this.
