I hold the wider Cisco org with as much contempt as any non-MBA technologist, but to be fair, the WebEx team appear to be doing some interesting things with zero trust [0], MLS [1], and watermarking [2].

A lot of mass market / SaaS comms tools are abysmal at best on the security front but it's nice to at least see some semblance of effort on a few layers of controls.
