Zoom. Why you should be concerned using it.

In the latest report by Citizen Lab, it was found that Zoom created its own encryption protocol. Zoom claimed that they were using AES-256 versus the AES-128 encryption method as discovered by the Citizen Lab report.

Given the substandard security, vulnerabilities and Zoom-bombing. It is best to seek alternatives.  If you are already using Office 365, Teams is already support in your environment.
