It seems that teleworking is doing its job in thousands of homes around the world and one of the options we have available for teleworking in the form of meetings and so on is the Zoom tool. In this case, the tool allows videoconferences with several people at the same time and without them having to have a Mac, it can be used on any PC or device.
This, which is very good for holding a meeting by video call without using the same operating system, is leading to a handful of criticism for the ways to encrypt all the information that users share in this service and it seems that it's not entirely safe.
There have already been several publications against Zoom and its malpractice in not informing users or how we can read in the middle The Intercept, the video conferencing service is not secure because it is basically not encrypting the content from end to end. This is bad for a clear reason and that is that everything that is broadcast directly on this platform is accessible from Zoom's servers and therefore the privacy of all these meetings or talks together with the materials that are exposed in it are totally unprotected.
El tweet from the expert in security, Felix (@ c1truz) clearly indicates that the program takes advantage of authentication to obtain authorization to access the system, just as it happens with typical malware programs, so it is important that users know about it:
If the App is already installed but the current user is not admin, they use a helper tool called “zoomAutenticationTool” and the AuthorizationExecuteWithPrivileges API to spawn a password prompt identifying as “System” (!!) to gain root (including a typo) . pic.twitter.com/gp9DVCoVCm

The best way to make a work video call on Mac is logically using FaceTime, but in the case that due to lack of an Apple team the meeting cannot be carried out with this great tool, the advice is that you use Skype, Hangouts or any other video call service for your work meetings.
and what do they recommend? not use it, use the web version, restrict permissions?
The best thing to do is use Skype. When the Zoom app doesn't have privacy security flaws on Mac, it does on iOS (like a few days ago).
In the article I talk about precisely those two programs that Nacho mentions, I hope they serve you
