UPDATE APRIL 4
In the two weeks since this blog post was initially written there has been more security and privacy issues with using Zoom come to light, presently no less than the FBI and 27 States Attorney General have investigations underway into these issues. Additionally it has come to light that contrary to Zoom's claim to be encrypted - it actually isn't. All communications via Zoom can be intercepted by third-parties and those communications are not encrypted.
As a duty of care, it would be our recommendation that unless there is absolutely none of the alternatives provided above that you can use, then you shouldn't use Zoom until the growing list of current issues are resolved.
