Unfortunately, no disclosure contacts were publicly available and we had to resort to emailing random people. The Paradox.ai security page just says that we do not have to worry about security!

Lol, reading that as someone who wants to disclose a vulnerability must be frustrating.

We're using whereby at our company and I really appreciate how simple and compatible it is. No App, no account (for guests), independent of browser and OS. I'd much rather use whereby than Teams or WebEx.
