Put your expectations of employees on the record, publish guidelines and some form of training for staff on how to observe best safety practices in meetings.

Ensure you have done the basics of good security settings on your meeting platform.

Accept that you must review meetings of high-risk users or a representative sample of your overall meetings to get any real picture of risk and exposure.

Set recording policies using your meeting platforms or third-party tools to capture those meetings.

Manually or using purpose-built technology, review those recordings and take appropriate action to address risks.
