A friends organization has banned Zoom for security reasons.

For on-line courses they would like conferencing software that supports:

  • breakout rooms
  • hand raising
  • doc sharing
  • video presentations (interruptible)
  • Not sure about the doc-sharing part (but I guess there's an addon for that): take a look at BigBlueButton. I just had my first talk on that platform yesterday (as the presenter/speaker). Definitely can confirm the first two points working great, and saw an option for the last. Allows to share your screen (all, or single window), which was how I put up my presentations. Has a whiteboard to paint/write on, lets you upload presentations to use "inline". Focus on education, interacts with lots of things. FOSS (free, open-source). 130 people joined, np

As mentioned in the question, that organisation has stopped using Zoom for security reasons therefore I will recommend Microsoft Teams.

Microsoft Teams allows hand raising, file sharing and storage, collaborate live in real time to work on same document. It has recently integrated whiteboard and breakout room functions also. Both free and paid plans are available with special plans for academic institutions and non profit organisations.

The best part is that we can take a demo of Microsoft Teams without sign up.

Google Classroom along with Google Meet is also a good alternative. Although currently it does not provide many features compared to its competitors, being a browser based application, some features could be incorporated into it using the already availabe Chrome extensions for it.

    You're suggesting that open source and free is less secure. Can you back that up, or remove that phrase?
