Some permanent or recurring meetings will be open to anyone to join if not properly secured. The Zoom meeting URL may become publicly available on the Internet and random people may join.
Here are some tips to secure your Zoom meetings further:
- Do not enable "Join before host" for permanent (recurring) virtual meeting rooms and personal meeting ID (PMI).
- Zoom administrators can consider disabling "Join before host" in Account Management -> Account Settings. Users will have to manually enable "Join before host" when creating meetings.
- Put a meeting password on the meeting and PMI.
- Limit specified domains to be allowed to join the meeting when creating the meeting.
- Lock the meeting once the meeting has started. This option is in Manage participants -> More.
